+VaX#n8 (real name unknown) wrote shared_src/fsys_ext2fs.c.
+
+Heiko Schroeder rewrote shared_src/stage1.S to be more readable.
+
+The following authors assigned copyright on their work to the Free
+Software Foundation:
+
+Erich Stefan Boleyn originally designed and implemented GRUB.
+
+Gordon Matzigkeit adopted GRUB into the GNU Project. He fixed several
+bugs, added symbolic link support to shared_src/fsys_ext2fs.c, and
+began the implementation of /sbin/grub. He was an official maintainer.
+
+Yoshinori K. Okuji contributed many bugfixes and new features, such as
+working LBA support, /sbin/grub support for configuration files, the
+script /sbin/grub-install, the utility /bin/mbchk, the new engine for
+builtin commands, disk swapping support, keyboard configuration support,
+network support, online help support, command-line history support,
+hidden menu support, the new Linux loader, serial terminal support,
+single-line editing support, the utility /sbin/grub-md5-crypt, the new
+GRUB manual, and several new commands. He is the current official
+maintainer.
+
+Peter Astrand added support for a color menu.
+
+Pavel Roskin contributed many bugfixes and new features, such as FreeBSD
+support for the grub shell, and configure process cleanups.
+
+Klaus Reichl wrote stage2/fsys_minix.c.
+
+Per Lundberg added graphics support to the Multiboot Specification.
+
+Jochen Hoenicke rewrote stage2/fsys_fat.c and wrote
+stage2/fsys_reiserfs.c and stage2/md5.c.
+
+Christoph Plattner added support for Net Boot Image Proposal.
+
+Frank Mehnert added support for hercules console.
+
+Kristoffer Branemyr added VSTa filesystem support.
+
+Serguei Tzukanov added JFS and XFS support.
+
+Jason Thomas added Linux DAC960 support and support for hiding/unhiding
+logical partitions, and did a significant bugfix for the terminal stuff.
+
+Tilmann Bubeck added support for vt100-incompatible terminals.
+
+KB Sriram added a better detection of FAT filesystem and fixed a
+network device completion.

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19yy name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+
+ From Ilguiz Latypov:
+ * configure.in: Fix a syntax error in a sed script.
+ * stage2/bios.c (get_diskinfo): PhoenixBIOS 4.0 Revision 6.0
+ for ZF Micro might understand the greater buffer size for the

+ Supposedly the BIOS assumes even bigger space is available and

+
+2002-12-11 Yoshinori K. Okuji <okuji@enbug.org>
+
+ Add a workaround for buggy BIOSes which don't pass boot drive
+ correctly. The idea is that GRUB forces the fixed disk flag
+ when booted from a hard disk. When BIOS loads GRUB directly,
+ the boot drive must be either of 0x00 and 0x80, so this should
+ work, if those BIOSes always pass zero to %dl. AFAIK, this
+ assumption is always correct.
+

+
+ * stage2/boot.c (load_image): For Linux, don't check if the

+ * grub/main.c (use_preset_menu): New variable.
+ (OPT_PRESET_MENU): New macro.

+ Check if PRESET_MENU is not NULL.

+ Try to open the preset menu first, and try to open the
+ configuration file, only if that failed.
+ Even if the preset menu was read, try to open the configuration
+ file. This time, opening the preset menu never succeed, because
+ close_preset_menu ensures that the preset menu is available at
+ most once.

+
+2000-08-30 OKUJI Yoshinori <okuji@gnu.org>
+
+ * configure.in (CPPFLAGS): Remove -Wundef by default. Add the

+
+ * grub/asmstub.c (CONVENTIONAL_MEMSIZE): Changed to 640 * 1024

+ (init_bios_info) [!STAGE1_5]: Change the type of CONT, MEMTMP
+ and ADDR to unsigned long from int.
+ Set EXTENDED_MEMORY to MBI.MEM_UPPER by default.
+ If MBI.MMAP_LENGTH is not zero, set EXTENDED_MEMORY to the
+ maximum available address, ignoring any memory holes.
+ If MBI.MMAP_LENGTH is zero but get_eisamemsize returns other

+
+ Add a dirty hack into the kernel loader so that the user can
+ force GRUB to load NetBSD ELF kernels. The support code is
+ mostly stolen from a patch by Pavel Roskin.
+
+ * stage2/boot.c (load_image): Added an optional argument
+ SUGGESTED_TYPE.
+ If BUFFER is a bootable ELF image and SUGGESTED_TYPE is
+ KERNEL_TYPE_NETBSD, then load it as an ELF image and set STR2 to
+ "NetBSD" and TYPE to SUGGESTED_TYPE.
+ If the image is a Linux kernel and SUGGESTED_TYPE is not
+ KERNEL_TYPE_NONE, make sure that SUGGESTED_TYPE matches up to
+ the Linux kernel type.
+ If TYPE is KERNEL_TYPE_NETBSD, set MEMADDR to
+ RAW_ADDR (phdr->paddr & 0xFFFFFF) like FreeBSD.
+ If SUGGESTED_TYPE is not KERNEL_TYPE_NONE, make sure that
+ SUGGESTED_TYPE is equal to TYPE.
+ (bsd_boot): If TYPE is not KERNEL_TYPE_FREEBSD (i.e. NetBSD or
+ OpenBSD) and the bit MB_INFO_AOUT_SYMS is set, set END_MARK to
+ MBI.SYMS.A.ADDR + 4 + MBI.SYMS.A.TABSIZE + MBI.SYMS.A.STRSIZE.
+ If the bit is clear, set END_MARK to 0.
+ Pass END_MARK to *ENTRY_ADDR instead of directly calculating the
+ end of symbols.
+ * stage2/shared.h (load_image): Added the argument
+ SUGGESTED_TYPE to the prototype.
+ * stage2/builtins.c (kernel_func): Added a new option,
+ `--type=TYPE'. Check if ARG is started with "--type=".
+ If so, set SUGGESTED_TYPE to KERNEL_TYPE_NETBSD,
+ KERNEL_TYPE_FREEBSD, KERNEL_TYPE_NETBSD, KERNEL_TYPE_LINUX,
+ KERNEL_TYPE_BIG_LINUX, KERNEL_TYPE_MULTIBOOT if ARG is "netbsd",
+ "freebsd", "openbsd", "linux", "biglinux", "multiboot",
+ respectively. Otherwise, set ERRNUM to ERR_BAD_ARGUMENT and
+ return 1. Set KERNEL_ARG to a string after the option.

+
+This is the GRUB. Welcome.
+
+This file contains instructions for compiling and installing the GRUB.
+
+The Requirements
+================
+
+GRUB depends on some software packages installed into your system. If
+you don't have any of them, please obtain and install them before
+configuring the GRUB.
+
+* GCC
+
+ Probably every recent GCC should work, but we recommend GCC 2.95 and
+ later, since you can create smaller binary images. See the web page
+ <http://gcc.gnu.org/>.
+
+* GNU Make
+
+ For now, the Makefiles produced by Automake depends on GNU Make. See
+ the web page <http://www.gnu.org/software/make/make.html>.
+
+* GNU binutils 2.9.1.0.23 or later
+
+ Binutils has changed the behavior of 16bit assembler between 2.9.1
+ and 2.9.1.0.x, and we support only 2.9.1.0.x and higher. In
+ particular, we recommend using binutils 2.10, since it is the only
+ public release that supports real 16bit mode. Please take a look at
+ the web page <http://sourceware.cygnus.com/binutils/>, for more
+ information. Note that you don't have to install it into any system
+ directory. See the section "Operation Controls", if you want to
+ install binutils into your own directory.
+
+If you'd like to develop GRUB, these below are also required. Don't
+forget to specify the option `--enable-maintainer-mode' when running the
+configure script.
+
+* Texinfo 4.0 or later
+
+ We use some new macros in the documents, so you need a recent
+ Texinfo release. See the web page
+ <http://www.gnu.org/software/texinfo/texinfo.html>.
+
+* Developers: GNU Autoconf 2.5x and GNU Automake 1.7 or later
+
+ You should not need Automake just to compile GRUB, but you will need
+ it if you edit any of the build files (Makefile.am, configure.in,
+ etc). We use the new "per-executable flags" feature found in the
+ latest release of automake. See the web page
+ <http://www.gnu.org/software/automake/automake.html>.
+
+
+Configuring the GRUB
+====================
+
+The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a
+file `config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+If you need to do unusual things to compile the package, please try to
+figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+The file `configure.in' is used to create `configure' by a program
+called `autoconf'. You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+
+Building the GRUB
+=================
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and
+ type `./configure' to configure the package for your system. If
+ you're using `csh' on an old version of System V, you might need
+ to type `sh ./configure' instead to prevent `csh' from trying to
+ execute `configure' itself.
+
+ Running `configure' takes awhile. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. `cd' to the directory where you want the object files
+and executables to go and run the `configure' script. `configure'
+automatically checks for the source code in the directory that
+`configure' is in and in `..'.
+
+
+Installation Names
+==================
+
+By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc. You can specify an
+installation prefix by giving `configure' the option `--prefix=PATH'.
+
+You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If
+you give `configure' the option `--exec-prefix=PATH', the package will
+use PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for
+particular kinds of files. Run `configure --help' for a list of the
+directories you can set and what kinds of files go in them.
+
+If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure'
+the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Please note, however, that the GRUB knows where it is located in the
+filesystem. If you have installed it in an unusual location, the
+system might not work properly, or at all. The chief utility of these
+options for the GRUB is to allow you to "install" in some alternate
+location, and then copy these to the actual root filesystem later.
+
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+
+Operation Controls
+==================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+ Use and save the results of the tests in FILE instead of
+ `./config.cache'. Set FILE to `/dev/null' to disable caching, for
+ debugging `configure'.
+
+`--help'
+ Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made.
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--version'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--enable-maintainer-mode'
+ Enable make rules and dependencies not useful (and sometimes
+ confusing) to the casual installer. If you are a GRUB developer,
+ it is a good idea to specify this option.
+
+`--disable-ext2fs'
+ Omit the ext2fs support in Stage 2.
+
+`--disable-fat'
+ Omit the FAT support in Stage 2.
+
+`--disable-ffs'
+ Omit the FFS support in Stage 2.
+
+`--disable-minix'
+ Omit the Minix fs support in Stage 2.
+
+`--disable-reiserfs'
+ Omit the ReiserFS support in Stage 2.
+
+`--disable-vstafs'
+ Omit the VSTa filesystem support in Stage 2.
+
+`--disable-jfs'
+ Omit the JFS support in Stage 2.
+
+`--disable-xfs'
+ Omit the XFS support in Stage 2.
+
+`--disable-ufs2'
+ Omit the UFS2 support in Stage 2.
+
+`--disable-iso9660'
+ Omit the ISO9660 support in Stage 2.
+
+`--disable-gunzip'
+ Omit the decompression support in Stage 2.
+
+`--disable-md5-password'
+ Omit the MD5 password support in Stage2.
+
+`--with-binutils=PATH'
+ Search the path PATH to find binutils. If you have installed your
+ binutils executables into an unusual location where GCC doesn't
+ search by default, use this option.
+
+`--without-curses'
+ Don't use the curses library.
+
+`--disable-hercules'
+ Omit the hercules console support in Stage 2.
+
+`--disable-serial'
+ Omit the serial terminal support in Stage 2.
+
+`--enable-serial-speed-simulation'
+ Simulate the slowness of a serial device in the grub shell. This
+ option is useful for GRUB developers, as you can test the
+ performance of a terminal emulation even on pseudo terminals.
+
+`--enable-preset-menu=FILE'
+ Preset a menu file FILE in Stage 2. This is useful, if you cannot
+ put a configuration file on a filesystem for some reason (e.g. when
+ you need to set the default terminal to a serial terminal in an
+ embedded system).
+
+`--enable-example-kernel'
+ Build the example Multiboot kernel in the directory "docs". You
+ will be able to boot the image "kernel" with GRUB.
+
+`--disable-auto-linux-mem-opt'
+ Don't pass the "mem=" option automatically, when booting Linux.
+ You can also disable the feature at run time.
+
+
+`configure' also accepts several options for the network support. See
+the file `netboot/README.netboot', for more information.

+
+This is a list of random notes for GRUB maintainers. If you are not a
+maintainer, you need to ask maintainers to do these instead of doing
+these yourself.
+
+How to update the online manual: (FIXME: this is obsoelete)
+1. Copy docs/*.texi (excluding "multiboot.texi") to fencepost.gnu.org.
+2. Make a symbolic link from ~mohit/gnudoc/gnudoc_template to the
+ directory under which *.texi were copied, if the link isn't present.
+3. Run ``~mohit/gnudoc/gendocs.sh grub "GNU GRUB Manual"''.
+4. Copy the contents of the directory ``manual'' to
+ gnudist.gnu.org:~ftp/gnu/Manuals/grub-VERSION (VERSION is, for
+ example, 1.0).
+5. Run ``ln -sf grub-VERSION grub'' in gnudist.gnu.org:~ftp/gnu/Manuals.
+6. Run ``cd grub; ln -s grub.html index.html''.
+7. Verify the new online manual with a WWW browser.
+8. Update manual.html by hand.
+
+How to release a version:
+1. Check out the source tree from the CVS from scratch.
+2. Check if ``make distcheck'' succeeds.
+3. Run ``util/grub-image''.
+4. Check the resulted images, for example, using bochs.
+5. Copy grub-VERSION.tar.gz, grub-VERSION-i386-pc.tar.gz and
+ grub-VERSION-i386-pc.ext2fs to fencepost.gnu.org:~ftp/gnu/grub.
+6. Move older files in that directory above to the directory ``old'',
+ if you think they are eyesores.
+7. Post an announcement to bug-grub@gnu.org. It would be a good idea to
+ send a carbon copy to bug-hurd@gnu.org and
+ debian-hurd@lists.debian.org. If the announcement is for a stable
+ version, you can inform info-gnu@gnu.org as well.
+8. Optionally, post an announcement to Freshmeat.net.
+
+Legal issues:
+1. If a patch is not significant (in size), you don't have to care about
+ the copyright.
+2. If a patch is significant, you shouldn't apply the patch to the CVS.
+ Before doing that, you must ask the contributor to assign or disclaim
+ the copyright. Send ``/gd/gnuorg/request-assign.changes'' or
+ ``/gd/gnuorg/request-assign.future'' to the contributor, and wait
+ until the FSF finishes the legal work.
+3. You can check if a contributor has already assigned his/her copyright
+ to the FSF by looking at ``/gd/gnuorg/copyright.list''.
+
+What you should have in your mind:
+1. Don't add features unnecessarily! You may think it is a Good Thing to
+ have more features, but you must be prepared for more burdens.
+ DO THAT ONLY IF YOU BELIEVE THAT THE FEATURE IS ESSENTIAL.
+2. Don't break backward-compatibility! Don't apply any patch which could
+ break existing features. Otherwise you would receive a lot of
+ complaints. DO THAT ONLY IF YOU BELIEVE THAT THE INCOMPATIBILITY IS
+ INEVITABLE.
+3. Write good code. Be not satisfied with ad hoc workarounds or quick
+ hacks. NEVER WRITE BAD CODE.

+NEWS - list of user-visible changes between releases of GRUB
+
+New in 0.97 - 2005-05-08:
+* Fix the prototypes and the definitions of nested functions. This was
+ required for gcc-4.
+* Implement a more robust workaround for buggy BIOSes which don't pass
+ boot drive correctly (notably for HP Vectra).
+
+New in 0.96 - 2005-01-30:
+* The command "fallback" supports mutiple fallback entries.
+* The command "savedefault" supports an optional argument which
+ is the number of next boot entry or the special keyword `fallback'.
+* New utility "grub-set-default".
+* New section "Making your system robust" in the manual.
+
+New in 0.95 - 2004-06-13:
+* Add support for ReiserFS 3.
+* Fix support for FreeBSD 5.
+* Support ATARAID for Linux in the grub shell and grub-install.
+* Add CDROM support for El Torito with no emulation mode. You can use
+ (cd) as a CDROM drive in the config file.
+* Option --no-mem-option is implied for Linux 2.4.18 and newer.
+* Add support for UFS2.
+
+New in 0.94 - 2004-01-25:
+* Support building on x86-64 with gcc -m32.
+* Use a BIOS call to turn on/off Gate A20. This should solve various
+ problems related to Gate A20 in modern BIOSes.
+* Add a workaround for buggy BIOSes (notably HP Vectra series) which
+ don't pass the boot drive correctly.
+* Display "GNU GRUB" instead of "GRUB" in the menu.
+* Add support for QNX RTP into the grub shell.
+* Add support for the initrd max address of a kernel header in Linux.
+* Support 32 bit and 64 bit dev_t.
+* Add support for an install device in GRUB's notation with no
+ parenthesis (e.g. grub-install hd0).
+* Improve the manual a lot.
+
+New in 0.93 - 2002-12-08:
+* Define the behavior of the boot loader when the load end address is
+ zero and the bss end address is zero in the Multiboot Specification.
+ Also, add the support into GRUB.
+* Finally, we have a Bug Tracking System! Now the preferable way to
+ report bugs is to use the BTS rather than sending e-mail to bug-grub.
+ See <http://bugcomm.enbug.org/?project=grub&mode=project>, for more
+ details.
+* The appendix "FAQ" in the manual is removed. See the GNU GRUB FAQ on
+ the web <http://www.gnu.org/software/grub/grub-faq.html> instead.
+* The terminal handling code is rewritten radically, and many bugfixes
+ are made at the same time.
+* The command "color" is effective even in the command-line.
+* The command "terminal" takes two new options, ``--no-echo'' and
+ ``--no-edit''. If you specify ``--no-echo'', GRUB won't echo back
+ input characters. If you specify ``--no-edit'', GRUB will disable the
+ BASH-like editing feature. These options are useful when using an
+ intelligent terminal (such as the comint mode in GNU Emacs).
+* The utility ``grub-md5-crypt'' prompts to retype a password and checks
+ if the passwords match.
+* Support for booting Linux is rewritten, so GRUB now supports
+ large-EBDA systems.
+* The menu interfaces supports Page Up, Page Down, and Right Key.
+* New command "terminfo", for vt100-incompatible terminals.
+* New options, ``-D'', ``-g'' and ``-m'' are supported for FreeBSD.
+
+New in 0.92 - 2002-04-30:
+* The command "displaymem" uses only hex digits for consistency.
+* The netboot code goes back to the progress bars instead of dots, for
+ the notation of data transfers. And, that is displayed only in debug
+ mode, that is to say, nothing is displayed by default. Remember that
+ you can turn on debug mode via the command "debug".
+* The command "help" doesn't show all the available commands by default,
+ when no argument is specified. Rarely used commands (such as
+ "testload") and useless commands in interactive use (such as
+ "savedefault") are hidden. If you want to see help messages for those
+ commands, specify the new option "--all".
+* A built-in, `more'-like pager is added. When a command prints too many
+ lines to fit the screen, GRUB waits until you hit return key. This
+ feature can be turned off by the new command "pager".
+* The command "terminal" accepts a new option, "--lines=LINES". You can
+ set the maximum number of lines arbitrarily with this option. If you
+ don't specify it, the maximum number will be 24.
+* The command "terminal" accepts another new option, "--silent". You can
+ suppress the "Press any key to continue" message with this option.
+* The mem= option for Linux is recognized and used to limit the maximum
+ address of initrd.
+* A fallback entry is executed immediately after a default entry,
+ without prompting a user's intervention, as the manual has ever been
+ saying.
+* The utility ``grub-install'' makes sure that GRUB images have been
+ written to a physical disk completely. To assist this feature, a new
+ command "dump" is added.
+
+New in 0.91 - 2002-01-21:
+* Support for Linux DAC960 is added.
+* JFS and XFS support is added.
+* The commands "hide" and "unhide" support logical partitions.
+* The utility ``grub-install'' supports NetBSD.
+* The network support is updated to Etherboot-5.0.5.
+* The manner of handling the preset menu changes. In the previous
+ implementation, the preset menu is used only when opening the
+ configuration file failed. Now try to use the preset menu first. And,
+ if the configuration file is available, it is read after readoing the
+ preset menu. In this case, menu entries in the preset menu (if any)
+ are overrided by the configuration file.
+* Diskless support is a bit changed. In the previous, GRUB set up a
+ network automatically via a special function. In the current, the
+ function is gone and the preset menu feature is used (i.e. just
+ execute the command "bootp" as if you specified it in the preset
+ menu). This has no impact against most users, but you should take care
+ if using the preset menu for your own purpose, because GRUB doesn't
+ call "bootp" implicitly when the preset menu is used explicitly. In
+ this case, you would probably need to insert commands to initialize a
+ network into your preset menu.
+* Important bugfixes are made for ReiserFS, APM, TFTP, LBA, etc.
+
+New in 0.90 - 2001-07-11:
+* The command "setkey" resets key mappings, when no argument is
+ specified.
+* Linux devfs support is added.
+* The utility ``grub-install'' accepts a new option, `--recheck'. If
+ this option is specified, probe a device map, even if it already
+ exists. You should use this option whenever you add/remove a disk.
+* The command "password" supports a md5 password if the option `--md5'
+ is given. This command can now also be used to protect specific menu
+ items with their own passwords.
+* New command, "displayapm".
+* New command, "md5crypt".
+* The new utility ``grub-md5-crypt'' is a frontend of the grub shell. It
+ encrypts a password in MD5 format.
+* New commands, "testvbe" and "vbeprobe".
+* The configure script accepts a new option, `--enable-preset-menu'. You
+ can embed an arbitrary configuration which will be used when Stage 2
+ cannot open a real configuration file, with this option. The argument
+ must be an existing file.
+* EZ-BIOS support is added.
+* Booting Windows from a logical partition is supported.
+* The example Multiboot kernel in the directory "docs" is built, if you
+ specify the option `--enable-example-kernel' to the configure script.
+* New command, "ifconfig".
+* Linux software RAID support is added (only for RAID-1).
+* Hercules support is added.
+* The configure script now accepts `--disable-auto-linux-mem-opt', which
+ has the same meaning as you specify the option `--no-mem-option' to the
+ command "kernel".
+* Jump to the physical entry address of a Multiboot kernel when booting
+ it up. The old behavior was to use the virtual one, regardless of the
+ setting of the physical address.
+* The commands "bootp" and "dhcp" accepts a new option
+ `--with-configfile', so that you can load a remotely specified
+ configuration file automatically, like the network boot images.
+* VSTa filesystem support is added.
+* ELF symbol loading support is added.
+
+New in 0.5.96 - 2000-10-04:
+* New commands, "reboot" and "halt".
+* New command, "hiddenmenu". You can hide the menu interface by default
+ with this command.
+* You can specify `--no-mem-option' to the command "kernel", if you want
+ GRUB not to pass a Linux's mem option automatically.
+* Now GRUB is compliant with the Linux/i386 boot protocol version 2.02.
+* The network support is updated to Etherboot-4.6.4.
+* Symlinks in ReiserFS are supported.
+* Add a workaround into the grub shell, so that it works fine even under
+ Linux 2.4.
+* Add a new option `--stage2' into the commands "install" and "setup",
+ to let the grub shell know what the file name of Stage 2 is under your
+ operating system. You must specify the option correctly, if you cannot
+ unmount the partition where GRUB images reside. We'd recommend _not_
+ using those commands directly, but using the utility "grub-install"
+ instead, because this is safer.
+* One violation against the Network Boot Image Proposal was found and
+ fixed. So now the image `nbgrub' can work fine even with a card such
+ as rtl8139.
+* Serial terminal support is added. The configure script accepts
+ a new option `--disable-serial'. Unless it is specified, you can use
+ two new commands, "serial" and "terminal" in the command-line and the
+ menu. See the manual, for more details.
+* Preserve the possible magic number used by Windows NT in a MBR.
+* The command-line interface is switched to single-line editing mode.
+* Only for developers: the configure script accepts
+ `--enable-serial-speed-simulation', which is useful when you want to
+ simulate the speed of a serial device on a psuedo terminal.
+* Also only for developers: you can specify an optional argument to the
+ option `--hold' for the grub shell. The argument means how many
+ seconds the grub shell should wait until diving into the main routine.
+* New command, "savedefault". Now you can save current entry number to
+ your disk with this command and then you can set the default boot
+ entry to it by the command "default saved".
+* Add a new option `--prefix' into the command "setup", so that you can
+ specify the name of a directory which contains GRUB images. And, the
+ behavior of this command changed slightly, that is, this command now
+ searchs stage1 automatically under "/boot/grub" and "/grub", unless
+ you specify the option `--prefix'.
+* The utility `grub-install' recognizes a separate boot partition
+ automatically.
+* New commands, "partnew" and "parttype". You can modify partition
+ tables with these commands.
+
+New in 0.5.95 - 2000-06-27:
+* NetBSD ELF kernel support is added. You have to specify the new option
+ to the command "kernel". See below.
+* Added a new option `--type=TYPE' into the command "kernel". This
+ option suggests what type of kernel you want to load. TYPE must be
+ either of "netbsd", "freebsd", "openbsd", "linux", "biglinux" and
+ "multiboot". Actually, this option will be necessary only if you want
+ to load a NetBSD ELF kernel, because GRUB can automatically determine
+ a kernel type in the other cases.
+* ReiserFS support is added.
+* Added a new option `--force-lba' into the command "install". This
+ option disables some sanity checks for LBA mode (but not all). If you
+ are sure that your machine supports LBA mode but GRUB doesn't work in
+ LBA mode, you should specify it. It is necessary if your BIOS is too
+ buggy. In the previous version, it was a compile-time option, but you
+ don't have to recompile GRUB any longer.
+* Likewise, now the command "setup" and the script "grub-install" also
+ accept `--force-lba' option. Specifying this option to "setup" or
+ "grub-install" has the same effect as to the command "install".
+* The configure script doesn't accept the option
+ `--disable-lba-support-bitmap-check' any longer. Use the option above.
+* The network support is updated to Etherboot-4.6.1. So now we have
+ 3Com59x and DEPCA drivers.
+* Now you can omit the configuration file argument to the command
+ "password". If you omit it, then GRUB will just unlock privileged
+ instructions (such as `c') when you enter a correct password.
+* The new command "lock" can be used to prevent end-users from executing
+ arbitrary menu entries. This command will emit an error until the user
+ enters a correct password.
+* Recognize the Linux extended partition type.
+* Pass a correct memory size to Linux and *BSD.
+* Diskless support is added. Now configure accepts --enable-diskless,
+ and "make" will produce two additional images, ``nbgrub'' for Net Boot
+ Image Proposal and ``pxegrub'' for Preboot Execution Environment. See
+ the documentation, for more details.
+* The command "tftpserver" overrides a TFTP server address returned by a
+ BOOTP server, a DHCP server or a RARP server.
+* Fix a serious bug about LBA support. It is possible that you don't
+ disable the LBA support bitmap check any longer. Please send a report,
+ if you must still disable it. We need to know if we should get rid of
+ the option.
+
+New in 0.5.94 - 2000-03-06:
+* Stage 1 supports both the LBA mode and the CHS mode.
+* The NetBSD and OpenBSD boot bug is fixed.
+* The more automatic installation command "setup" is added.
+* The command "embed" embeds a Stage 1.5 in the sectors after a MBR.
+* Support symbolic color name syntax in the command "color".
+* The grub shell loads the BIOS drive mapping information from a device
+ map file if it is specified and can be opened. If not found, try to
+ create it based on the guessed information.
+* NetBSD support in the grub shell is improved.
+* A simple checker for the format of a Multiboot kernel, ``mbchk'', is
+ added.
+* The command "find" searches for a filename in all devices and print
+ the list of the devices which contain the file.
+* The command "map" maps a drive to another drive so that we can
+ chain-load some foolish operating systems (such as DOS) even if such
+ an operating system resides at a non-first drive.
+* The command "setkey" maps a key to another.
+* The GRUB manual is rewritten, and now consists of three parts and
+ appendices.
+* The command "ioprobe" detects what I/O ports are used for a BIOS
+ drive.
+* OpenBSD support in the grub shell is improved.
+* The command "install" can now patch a Stage 2 with a different
+ filename from "/boot/grub/menu.lst" even if a Stage 1.5 is used.
+* New program, ``grub-install''.
+* The command "blocklist" prints the blocklist notation of a file.
+* The command "chainloader" now accepts an option "--force", which is
+ required if you want to chain-load a boot loader defective in the
+ signature, such as SCO Unixware 7.1.
+* The netboot support is heavily rewritten, based on Etherboot-4.4.3.
+ Most of the device drivers are stolen from it, so we now have many
+ network drivers. See netboot/README.netboot for more details.
+* Now configure accepts the option `--disable-lba-support-bitmap-check'
+ to ignore an incorrect LBA support bitmap returned by a buggy BIOS. If
+ you are sure that your BIOS does support LBA mode but GRUB doesn't
+ work in LBA mode, recompile GRUB with this option specified. You can
+ check if GRUB accesses a drive in LBA mode by the command "geometry".
+* New commands "bootp", "dhcp" and "rarp" can be used to initialize a
+ network device and get IP addresses from a network.
+* Long filename support in the FAT filesystem is added.
+* The command "cmp" compares each bytes in two files.
+
+New in 0.5.93 - 1999-10-30:
+* ELF format of FreeBSD kernel is supported.
+* Support the partition ids for NetBSD and OpenBSD.
+* Exit from the grub shell just by pushing the key `q' in the menu.
+* New options for configure can disable some functions in Stage 2. See
+ the output from `configure --help' for more information.
+* FAT32 support is added.
+* Minix fs support is added.
+* New commands "hide" and "unhide".
+* The character `=' after a command is not necessary any longer, but it
+ is supported for backward compatibility.
+* The command "help" displays helpful information about builtin
+ commands.
+* The command "geometry" displays the information of a drive specified
+ and set the geometry to arbitrary C/H/S values if the optional
+ arguments are used.
+* The command "configfile" loads a configuration file interactively.
+* The command "device" assigns a BIOS drive to an arbitrary filename in
+ the grub shell.
+* The option `--no-floppy' force the grub shell to assume that there is
+ no floppy, and the option `--probe-second-floppy' enables the probe of
+ the second floppy drive.
+* Integrated the netboot support in the Dresden version of GRUB.
+* FreeBSD support in the grub shell is improved.
+* Killing (C-u and C-k), yanking (C-y) and manipulating the history
+ (C-p and C-n) are supported.
+* The address argument for the command "install" is now optional.
+* Better completion support.
+* The command "cat" displays the contents of a file.
+
+New in 0.5.92 - 1999-07-26:
+* Bug fixes (i.e. Stage 1.5 can work fine again).
+* The /sbin/grub stage2 simulator now works at least on GNU/Linux, and
+ uses the Linux HDIO_GETGEO ioctl to determine hard disk geometry.
+* TAB not only lists filenames, but also completes a filename when the
+ filename is unique.
+* Password is not echoed back, put an asterisk for each of input
+ characters.
+* stage2_debug is removed, and the debugging features are added into
+ stage2.
+* Color menu support.
+* New command "quit".
+* The man page for /sbin/grub.
+* All documents become Texinfo.
+* Linux video mode selection is supported.
+* The new Stage 1 `stage1_lba' supports LBA addressing mode.
+
+New in 0.5.91 - 1999-03-14, Gordon Matzigkeit:
+* LBA and preliminary AWARD BIOS disk extension support.
+* Started docs/grub.texi.
+* /sbin/grub GUI now works (but it doesn't yet access disks properly).
+ Run `configure --enable-sbin-grub' to build this program in the grub
+ subdirectory.
+
+New in 0.5.90 - 1999-03-01, Gordon Matzigkeit:
+* Bug fixes.
+* GRUB understands symlinks on ext2fs (but still not ffs).
+* Many source code and build cleanups to comply with GNU standards.
+
+New in 0.5 - 1998-08-20, Erich Boleyn:
+
+* Improved error messages in the stage1 to be strings (easier to read
+ than the previous case of single characters), and removed any
+ display in the case of no error (less confusing).
+
+* New document describing error conditions and messages.
+
+* Improved configure/build process.
+
+* Made the early bootup interrupt-safe. Wasn't doing cli/sti when
+ necessary sometimes.
+
+* GRUB now shuts off the floppy before transferring control to any
+ other programs/modules/loaders. (chain-loading doesn't matter here,
+ just loading 32-bit modules/kernels)
+
+* Fixed a few stupid bugs, including a several in the ext2fs code.
+
+* Linux boot format support extended from just "zImage" to include
+ "bzImage" and initial ramdisk (also called "initrd") support for
+ both. "initrd" support is untested, but the critical parts were
+ taken from a supplied patch and seem OK.
+
+* Several new command features. See the command-listing for details.
+
+New in 0.4 - 1998-03-19, Erich Boleyn:
+
+* GRUB now correctly points ES:SI at a partition descriptor when
+ chain-loading.
+
+* Many minor bugs fixed (some in the build scripts).
+
+* Intel MPS 1.4 config/check code is totally new, and the "syscmd="
+ command is completely removed. Check command-listing for details.
+
+Version 0.4-pre, Erich Boleyn:
+
+* Reorganized docs, moved most "NOTE" items to a FAQ (with new entries
+ as well).
+
+* Now supports automatic decompression of any files loaded via the
+ GRUB stage2 filesystem code. Simply compress the file using GNU
+ gzip normally, then when loading, the GRUB internals will see the
+ contents in the decompressed state... i.e. all GRUB functions
+ operate normally as if it is the uncompressed file. An extra
+ version of the "module" loading function has been added which
+ disables this functionality if desired (in all the other cases, not
+ decompressing doesn't make sense).
+
+* Changed device strings used in filesystem code to more logical
+ format. Added "relative" disk and partition capability, see
+ command-listing and filesystem syntax description for details.
+
+* "install=" command vastly improved. Also moved to non-debug area.
+ Check command-listing and install documentation for details.
+
+* Added several new commands: "rootnoverify=", "uppermem=", and a new
+ debug command "displaymem". Check command-listing for details.
+
+* Added versioning numbers (and subsequently broke compatibility with
+ some of the previous code, so GRUB should be re-installed!).
+
+* Added unattended booting support via new "fallback=" command.
+
+* During debug probe of SMP configuration table compatible with Intel
+ MPS 1.4 standard, GRUB now checks for a pointer in the EBDA.
+
+* Using a "default=" entry greater than 11 caused the UI to do funny
+ things (it didn't pre-scroll the list to the appropriate place).
+
+* Reading files on FAT floppies had yet more problems related by many
+ users of version 0.3 6/17/96. Again, all known problems fixed.
+
+* "Extended" partitions now work (still cannot make an extended
+ partition active with "makeactive" command).
+
+* The build environment is greatly simplified, now using an
+ autoconf-like "configure" script.
+
+New in 0.3-19960617 - 1996-06-17, Erich Boleyn:
+
+* Yet more documentation improvements.
+
+* Known bugs in floppy operation fixed (12-bit FAT didn't work for
+ most cases, and inserting other floppies didn't flush the filesystem
+ cache).
+
+* NASTY uninitialized pointer bug causing "raw" floppy operation to
+ crash on several PCs is now fixed. This seems to have been the root
+ cause of all of the compatibility problems that have currently been
+ observed.
+
+* debug-mode command added to automate most difficult step of
+ installation for common cases (new install method #4).
+
+* Testing "mini-debugger" now merged with command-line when "DEBUG"
+ defined in compile (no SYSDEBUG option anymore). See description of
+ commands in the command-line for details.
+
+New in 0.3-19960602 - 1996-06-02, Erich Boleyn:
+
+* Completed initial licenses.
+
+* Initial filesystem documentation written.
+
+* Block-list and FAT filesystems now work as documented (in
+ particular, for the blocklist filesystem, shortcuts like "+1" for
+ "0+1,512" now work correctly).
+
+* Fixed several problems (old and new) in the various filesystems (for
+ example, the ext2fs filesystem code is now much faster, as it caches
+ some mapping blocks where it didn't at all before). Filesystem
+ semantics are much more uniform as well (symbolic links and reading
+ a directory as a file now return errors where it would silently fail
+ before).
+
+* "makeactive" now works for standard PC partitions on hard disks (not
+ extended partitions... so any PC partition number above 3 will give
+ a "no such partition" error). If a BSD sub-partition is is used, it
+ will ignore it, and only use the primary PC partition number.
+
+New in 0.3-19960520 - 1996-05-20, Erich Boleyn:
+
+* Updated instructions (though still very sparse).
+
+* New floppy probe (works much like the Linux floppy boot probe)
+ attempts to find the size of a floppy in a drive. Might still need
+ work! Please try on various floppy drives with various media!
+
+* New floppy handler will claim a non-existent drive if the floppy
+ disk isn't present in the drive. (for example, it won't be on the
+ list of installed drives unless a floppy is present)
+
+* Stage1 now compatible with both a hard disk MBR and the DOS BIOS
+ parameter block (see "install/README" for more details on how this
+ can be used).
+
+* Block-list filesystem partially works, as described in the file
+ "NOTES". Loading an a.out or elf kernel won't work with it, but all
+ other filetypes pretty much should. (certainly chain-loading works
+ OK)
+
+ NOTE: you must use the full format "0+1,512" for just he first
+ block... no parameters can be implicit in this version.. THis is
+ being fixed too.
+
+* Linux ext2 filesystem works. (it's very slow for big files, but
+ this is being fixed)
+
+* Linux boot type now supported. Use a standard piggybacked image as
+ with LILO. Put in hack to support >64MB via GRUB placing the RAM
+ size as the first item on the command-line automatically. Must pass
+ root partition on command-line using normal Linux syntax... if not,
+ it uses it's builtin root partition.
+
+* Supports chain-loading. For details, see "COMMANDS" and the
+ examples directory. (was able to boot DOS and Windows NT on my test
+ box). NOTE that the "root partition" must be set to work right.
+ "makeactive" is currently a no-op.
+
+* Several weird bugs fixed. One important note: If you recompile, it
+ will warn about a clash with builtin "strcmp". This is normal...
+ do NOT remove the strcmp definition, as then GCC will possibly put
+ inline code from it's own builtin function in some places. (my
+ strcmp has slightly different functionality, hence the problem)
+
+* Mini-debugger is currently broken.
+
+New in 0.2 - 1996-04-12, Erich Boleyn:
+
+* Completely new menu-based UI. See "COMMANDS" and the examples
+ directory for details. NOTE that the argument to a command must be
+ preceded by a space between it and the '=', in both the config file
+ and the command-line. This will be fixed.
+
+New in 0.1 - 1996-03-31, Erich Boleyn:
+
+* Newer version of Multiboot Standard (version 0.6) supported.
+
+* Autodetects kernel types. Supports Multiboot, FreeBSD, NetBSD
+ (Linux isn't finished).
+
+* Stage 1.5 works now. Default setup is now for working with a BSD
+ FFS floppy loading "/grub/stage2" as the main bootloader.
+
+* Filesystem support improved. It didn't work on many floppies before
+ (problem with the partition-detection code).
+
+* Memory probe now supports arbitrary amounts of RAM (some technical
+ limitations exist, see Multiboot standard version 0.6 for details).
+
+* A mini-debugger is included by default, activated by hitting '~' on
+ the command-line (it might interfere with things, but it seems OK
+ for my alpha-testing). The commands are in the function
+ "enter_sysdebug" defined in "common.c". If you have an Intel MPS-
+ compatible machine, there are extra commands enabled for SMP cpu
+ testing. 'q' exits and goes back to what you were doing before.
+
+New in 0.0-19960206 - 1996-02-06, Erich Boleyn:
+
+* Newer version of Multiboot Standard (version 0.4) supported.
+
+New in 0.0-19951210 - 1995-12-10, Erich Boleyn:
+
+* You can now perform TAB-based completion listing of any valid
+ partially completed disk/partition/file-name combination. Try it
+ out to see what you like, examples are in the NOTES file under
+ "Device completion".
+
+* Fixed a bug causing the memory size routine to sometimes report
+ ridiculous values.
+
+* Fixed some documentation (what little there is :-/ and a few
+ assembly bugs in the BIOS access routines that nobody reported yet,
+ so I won't detail it here.

+This is GNU GRUB, the GRand Unified Bootloader. GRUB is intended to
+provide important bootloader features that are missing from typical
+personal computer BIOSes:
+
+ - provides fully-featured command line and graphical interfaces
+ - recognizes fdisk partitions and BSD disklabels
+ - can dynamically read Linux ext2fs, ReiserFS, JFS and XFS, BSD ufs,
+ MS-DOS FAT16 and FAT32, Minix fs, and VSTa fs filesystems, plus
+ hardcoded blocklists
+ - can boot Multiboot-compliant kernels (such as GNU Mach), as well
+ as standard Linux and *BSD kernels
+
+See the file NEWS for a description of recent changes to GRUB.
+
+If you are interested in the network support, see the file
+README.netboot under the directory netboot.
+
+See the file INSTALL for instructions on how to build and install the
+GRUB data and program files. See the GRUB manual for details about
+using GRUB as your boot loader. Type "info grub" in the shell prompt.
+
+Please visit the official web page of GNU GRUB, for more information.

+
+Before working on anything in this file, it's very important that you
+make contact with the core GRUB developers. Things herein might be
+slightly out of date or otherwise not easy to understand at first
+glance. So write to <bug-grub@gnu.org> first.
+
+Priorities:
+ Reported bugs generally have top priority.
+ Non-reported and non-encountered bugs (things we know don't work,
+ but don't really impede things) have lower priority.
+ Things in this file are ranked with one to three !; the more, the
+ higher priority.
+
+
+Things that should be done before 1.0:
+
+* Finish the Multiboot Speicification 0.7. !!!
+
+* Add more --disable-FOO options to configure, so that you can create a
+ minimum GRUB image. This is useful for boot floppies because of the size
+ restriction. !
+
+* Implement a new version of track_int13, using Virtual 8086 Mode. !!!
+
+* Add missing features of graphics support. !!
+
+Things that should _not_ be done before 1.0:
+
+* Add configuration inclusion support by adding a command "include". !
+
+* Add automatic configuration support.
+
+* Add bunzip2 support.
+
+* Define the module system.
+
+* Add BSD syntax support, using results of ioprobe to map drives. !
+ (0x1f0-0x1f7 = primary IDE, 0x170-0x176 = secondary,
+ 0x1e8-0x1ef = tertiary, 0x168-0x16f = quaternary).
+
+* Add a real scripting language, possibly retaining backward
+ compatibility so that old config files can be used.
+
+* Add internationalization support, emulating gettext as much as is
+ feasible.
+
+* Support other architectures than i386-pc.
+
+* Add real memory management.
+
+
+Things that may be done anytime:
+
+* Port the script ``grub-install'' to OpenBSD. At least you will have to
+ modify the function `convert' so that it can translate a native device
+ name into the corresponding GRUB drive representation. !
+
+* Add a command to run a GRUB script file. !!
+
+* Add commands to manipulate the menu from the command-line interface. !
+
+* Make symbolic links work for BSD FFS.
+
+* Add indirect block support to the BSD FFS filesystem code, so files
+ larger than 16MB can be read.
+
+* Fix-up FreeBSD, NetBSD (and OpenBSD ?) command-line boot
+ parameters.
+
+* Support embedding a Stage 1.5 in the "bootloader" area of a FFS
+ partition. (We already have the code, but need an approval by an
+ expert before turning on the support. Any volunteers?)
+
+* Support embedding a Stage 1.5 in the EXT2_BOOT_LOADER_INO of an ext2fs
+ partition, so that it won't be accidentally erased or modified by
+ the kernel.
+
+* Add ISA PnP support.
+
+* Add more filesystems support (NTFS, etc.)
+
+* Add more remote console support (parallel and net).
+
+* Add (real) RAID support.
+
+? Add a partition naming syntax that means ``the first partition of
+ this type''. We need this for clean Hurd install floppies.
+ Nope. Improving the `find' command would solve this problem.
+
+* Add CDROM-chainloading support. It would be enough to support only
+ BIOSes which have bootable-CDROM support (so you may use the "Bootable
+ CDROM" BIOS calls). It is not trivial to support BIOSes without the
+ capability to boot CDROM.
+
+? Divide pxegrub into two parts, so the initial image doesn't exceed
+ the 32KB limit. I'm not sure if this is really necessary, because the
+ PXE standard just says that it is _recommended_ to improve the
+ modularity of a boot image. Obviously, this reason doesn't apply to
+ GRUB, as pxegrub is merely a secondary boot loader. So whether this
+ task should be done depends on if existing PXE ROMs support >32KB
+ images or not, after all.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+@node Overview
+@section Overview
+
+Briefly, a @dfn{boot loader} is the first software program that runs when
+a computer starts. It is responsible for loading and transferring
+control to an operating system @dfn{kernel} software (such as Linux or
+GNU Mach). The kernel, in turn, initializes the rest of the operating
+system (e.g. a GNU system).
+
+GNU GRUB is a very powerful boot loader, which can load a wide variety
+of free operating systems, as well as proprietary operating systems with
+chain-loading@footnote{@dfn{chain-load} is the mechanism for loading
+unsupported operating systems by loading another boot loader. It is
+typically used for loading DOS or Windows.}. GRUB is designed to
+address the complexity of booting a personal computer; both the
+program and this manual are tightly bound to that computer platform,
+although porting to other platforms may be addressed in the future.
+
+One of the important features in GRUB is flexibility; GRUB understands
+filesystems and kernel executable formats, so you can load an arbitrary
+operating system the way you like, without recording the physical
+position of your kernel on the disk. Thus you can load the kernel
+just by specifying its file name and the drive and partition where the
+kernel resides.
+
+When booting with GRUB, you can use either a command-line interface
+(@pxref{Command-line interface}), or a menu interface (@pxref{Menu
+interface}). Using the command-line interface, you type the drive
+specification and file name of the kernel manually. In the menu
+interface, you just select an OS using the arrow keys. The menu is
+based on a configuration file which you prepare beforehand
+(@pxref{Configuration}). While in the menu, you can switch to the
+command-line mode, and vice-versa. You can even edit menu entries
+before using them.
+
+In the following chapters, you will learn how to specify a drive, a
+partition, and a file name (@pxref{Naming convention}) to GRUB, how to
+install GRUB on your drive (@pxref{Installation}), and how to boot your
+OSes (@pxref{Booting}), step by step.
+
+Besides the GRUB boot loader itself, there is a @dfn{grub shell}
+@command{grub} (@pxref{Invoking the grub shell}) which can be run when
+you are in your operating system. It emulates the boot loader and can
+be used for installing the boot loader.
+
+
+@node History
+@section History of GRUB
+
+GRUB originated in 1995 when Erich Boleyn was trying to boot the GNU
+Hurd with the University of Utah's Mach 4 microkernel (now known as GNU
+Mach). Erich and Brian Ford designed the Multiboot Specification
+(@pxref{Top, Multiboot Specification, Motivation, multiboot, The Multiboot
+Specification}), because they were determined not to add to the large
+number of mutually-incompatible PC boot methods.
+
+Erich then began modifying the FreeBSD boot loader so that it would
+understand Multiboot. He soon realized that it would be a lot easier
+to write his own boot loader from scratch than to keep working on the
+FreeBSD boot loader, and so GRUB was born.
+
+Erich added many features to GRUB, but other priorities prevented him
+from keeping up with the demands of its quickly-expanding user base. In
+1999, Gordon Matzigkeit and Yoshinori K. Okuji adopted GRUB as an
+official GNU package, and opened its development by making the latest
+sources available via anonymous CVS. @xref{Obtaining and Building
+GRUB}, for more information.
+
+
+@node Features
+@section GRUB features
+
+The primary requirement for GRUB is that it be compliant with the
+@dfn{Multiboot Specification}, which is described in @ref{Top, Multiboot
+Specification, Motivation, multiboot, The Multiboot Specification}.
+
+The other goals, listed in approximate order of importance, are:
+
+@itemize @bullet{}
+@item
+Basic functions must be straightforward for end-users.
+
+@item
+Rich functionality to support kernel experts and designers.
+
+@item
+Backward compatibility for booting FreeBSD, NetBSD, OpenBSD, and
+Linux. Proprietary kernels (such as DOS, Windows NT, and OS/2) are
+supported via a chain-loading function.
+@end itemize
+
+Except for specific compatibility modes (chain-loading and the Linux
+@dfn{piggyback} format), all kernels will be started in much the same
+state as in the Multiboot Specification. Only kernels loaded at 1 megabyte
+or above are presently supported. Any attempt to load below that
+boundary will simply result in immediate failure and an error message
+reporting the problem.
+
+In addition to the requirements above, GRUB has the following features
+(note that the Multiboot Specification doesn't require all the features
+that GRUB supports):
+
+@table @asis
+@item Recognize multiple executable formats
+Support many of the @dfn{a.out} variants plus @dfn{ELF}. Symbol
+tables are also loaded.
+
+@item Support non-Multiboot kernels
+Support many of the various free 32-bit kernels that lack Multiboot
+compliance (primarily FreeBSD, NetBSD, OpenBSD, and
+Linux). Chain-loading of other boot loaders is also supported.
+
+@item Load multiples modules
+Fully support the Multiboot feature of loading multiple modules.
+
+@item Load a configuration file
+Support a human-readable text configuration file with preset boot
+commands. You can also load another configuration file dynamically and
+embed a preset configuration file in a GRUB image file. The list of
+commands (@pxref{Commands}) are a superset of those supported on the
+command-line. An example configuration file is provided in
+@ref{Configuration}.
+
+@item Provide a menu interface
+A menu interface listing preset boot commands, with a programmable
+timeout, is available. There is no fixed limit on the number of boot
+entries, and the current implementation has space for several hundred.
+
+@item Have a flexible command-line interface
+A fairly flexible command-line interface, accessible from the menu,
+is available to edit any preset commands, or write a new boot command
+set from scratch. If no configuration file is present, GRUB drops to
+the command-line.
+
+The list of commands (@pxref{Commands}) are a subset of those supported
+for configuration files. Editing commands closely resembles the Bash
+command-line (@pxref{Command Line Editing, Bash, Command Line Editing,
+features, Bash Features}), with @key{TAB}-completion of commands,
+devices, partitions, and files in a directory depending on context.
+
+@item Support multiple filesystem types
+Support multiple filesystem types transparently, plus a useful explicit
+blocklist notation. The currently supported filesystem types are
+@dfn{BSD FFS}, @dfn{DOS FAT16 and FAT32}, @dfn{Minix fs}, @dfn{Linux
+ext2fs}, @dfn{ReiserFS}, @dfn{JFS}, @dfn{XFS}, and @dfn{VSTa
+fs}. @xref{Filesystem}, for more information.
+
+@item Support automatic decompression
+Can decompress files which were compressed by @command{gzip}. This
+function is both automatic and transparent to the user (i.e. all
+functions operate upon the uncompressed contents of the specified
+files). This greatly reduces a file size and loading time, a
+particularly great benefit for floppies.@footnote{There are a few
+pathological cases where loading a very badly organized ELF kernel might
+take longer, but in practice this never happen.}
+
+It is conceivable that some kernel modules should be loaded in a
+compressed state, so a different module-loading command can be specified
+to avoid uncompressing the modules.
+
+@item Access data on any installed device
+Support reading data from any or all floppies or hard disk(s) recognized
+by the BIOS, independent of the setting of the root device.
+
+@item Be independent of drive geometry translations
+Unlike many other boot loaders, GRUB makes the particular drive
+translation irrelevant. A drive installed and running with one
+translation may be converted to another translation without any adverse
+effects or changes in GRUB's configuration.
+
+@item Detect all installed @sc{ram}
+GRUB can generally find all the installed @sc{ram} on a PC-compatible
+machine. It uses an advanced BIOS query technique for finding all
+memory regions. As described on the Multiboot Specification (@pxref{Top,
+Multiboot Specification, Motivation, multiboot, The Multiboot
+Specification}), not all kernels make use of this information, but GRUB
+provides it for those who do.
+
+@item Support Logical Block Address mode
+In traditional disk calls (called @dfn{CHS mode}), there is a geometry
+translation problem, that is, the BIOS cannot access over 1024
+cylinders, so the accessible space is limited to at least 508 MB and to
+at most 8GB. GRUB can't universally solve this problem, as there is no
+standard interface used in all machines. However, several newer machines
+have the new interface, Logical Block Address (@dfn{LBA}) mode. GRUB
+automatically detects if LBA mode is available and uses it if
+available. In LBA mode, GRUB can access the entire disk.
+
+@item Support network booting
+GRUB is basically a disk-based boot loader but also has network
+support. You can load OS images from a network by using the @dfn{TFTP}
+protocol.
+
+@item Support remote terminals
+To support computers with no console, GRUB provides remote terminal
+support, so that you can control GRUB from a remote host. Only serial
+terminal support is implemented at the moment.
+@end table
+
+
+@node Role of a boot loader
+@section The role of a boot loader
+
+The following is a quotation from Gordon Matzigkeit, a GRUB fanatic:
+
+@quotation
+Some people like to acknowledge both the operating system and kernel when
+they talk about their computers, so they might say they use
+``GNU/Linux'' or ``GNU/Hurd''. Other people seem to think that the
+kernel is the most important part of the system, so they like to call
+their GNU operating systems ``Linux systems.''
+
+I, personally, believe that this is a grave injustice, because the
+@emph{boot loader} is the most important software of all. I used to
+refer to the above systems as either ``LILO''@footnote{The LInux LOader,
+a boot loader that everybody uses, but nobody likes.} or ``GRUB''
+systems.
+
+Unfortunately, nobody ever understood what I was talking about; now I
+just use the word ``GNU'' as a pseudonym for GRUB.
+
+So, if you ever hear people talking about their alleged ``GNU'' systems,
+remember that they are actually paying homage to the best boot loader
+around@dots{} GRUB!
+@end quotation
+
+We, the GRUB maintainers, do not (usually) encourage Gordon's level of
+fanaticism, but it helps to remember that boot loaders deserve
+recognition. We hope that you enjoy using GNU GRUB as much as we did
+writing it.

+The device syntax used in GRUB is a wee bit different from what you may
+have seen before in your operating system(s), and you need to know it so
+that you can specify a drive/partition.
+
+Look at the following examples and explanations:
+
+@example
+(fd0)
+@end example
+
+First of all, GRUB requires that the device name be enclosed with
+@samp{(} and @samp{)}. The @samp{fd} part means that it is a floppy
+disk. The number @samp{0} is the drive number, which is counted from
+@emph{zero}. This expression means that GRUB will use the whole floppy
+disk.
+
+@example
+(hd0,1)
+@end example
+
+Here, @samp{hd} means it is a hard disk drive. The first integer
+@samp{0} indicates the drive number, that is, the first hard disk, while
+the second integer, @samp{1}, indicates the partition number (or the
+@sc{pc} slice number in the BSD terminology). Once again, please note
+that the partition numbers are counted from @emph{zero}, not from
+one. This expression means the second partition of the first hard disk
+drive. In this case, GRUB uses one partition of the disk, instead of the
+whole disk.
+
+@example
+(hd0,4)
+@end example
+
+This specifies the first @dfn{extended partition} of the first hard disk
+drive. Note that the partition numbers for extended partitions are
+counted from @samp{4}, regardless of the actual number of primary
+partitions on your hard disk.
+
+@example
+(hd1,a)
+@end example
+
+This means the BSD @samp{a} partition of the second hard disk. If you
+need to specify which @sc{pc} slice number should be used, use something
+like this: @samp{(hd1,0,a)}. If the @sc{pc} slice number is omitted,
+GRUB searches for the first @sc{pc} slice which has a BSD @samp{a}
+partition.
+
+Of course, to actually access the disks or partitions with GRUB, you
+need to use the device specification in a command, like @samp{root
+(fd0)} or @samp{unhide (hd0,2)}. To help you find out which number
+specifies a partition you want, the GRUB command-line
+(@pxref{Command-line interface}) options have argument
+completion. This means that, for example, you only need to type
+
+@example
+root (
+@end example
+
+followed by a @key{TAB}, and GRUB will display the list of drives,
+partitions, or file names. So it should be quite easy to determine the
+name of your target partition, even with minimal knowledge of the
+syntax.
+
+Note that GRUB does @emph{not} distinguish IDE from SCSI - it simply
+counts the drive numbers from zero, regardless of their type. Normally,
+any IDE drive number is less than any SCSI drive number, although that
+is not true if you change the boot sequence by swapping IDE and SCSI
+drives in your BIOS.
+
+Now the question is, how to specify a file? Again, consider an
+example:
+
+@example
+(hd0,0)/vmlinuz
+@end example
+
+This specifies the file named @samp{vmlinuz}, found on the first
+partition of the first hard disk drive. Note that the argument
+completion works with file names, too.
+
+That was easy, admit it. Now read the next chapter, to find out how to
+actually install GRUB on your drive.
+
+
+@node Installation
+@chapter Installation
+
+In order to install GRUB as your boot loader, you need to first
+install the GRUB system and utilities under your UNIX-like operating
+system (@pxref{Obtaining and Building GRUB}). You can do this either
+from the source tarball, or as a package for your OS.
+
+After you have done that, you need to install the boot loader on a
+drive (floppy or hard disk). There are two ways of doing that - either
+using the utility @command{grub-install} (@pxref{Invoking
+grub-install}) on a UNIX-like OS, or by running GRUB itself from a
+floppy. These are quite similar, however the utility might probe a
+wrong BIOS drive, so you should be careful.
+
+Also, if you install GRUB on a UNIX-like OS, please make sure that you
+have an emergency boot disk ready, so that you can rescue your computer
+if, by any chance, your hard drive becomes unusable (unbootable).
+
+GRUB comes with boot images, which are normally put in the directory
+@file{/usr/lib/grub/i386-pc}. If you do not use grub-install, then
+you need to copy the files @file{stage1}, @file{stage2}, and
+@file{*stage1_5} to the directory @file{/boot/grub}, and run the
+@command{grub-set-default} (@pxref{Invoking grub-set-default}) if you
+intend to use @samp{default saved} (@pxref{default}) in your
+configuration file. Hereafter, the directory where GRUB images are
+initially placed (normally @file{/usr/lib/grub/i386-pc}) will be
+called the @dfn{image directory}, and the directory where the boot
+loader needs to find them (usually @file{/boot/grub}) will be called
+the @dfn{boot directory}.

+@node Creating a GRUB boot floppy
+@section Creating a GRUB boot floppy
+
+To create a GRUB boot floppy, you need to take the files @file{stage1}
+and @file{stage2} from the image directory, and write them to the first
+and the second block of the floppy disk, respectively.
+
+@strong{Caution:} This procedure will destroy any data currently stored
+on the floppy.
+
+On a UNIX-like operating system, that is done with the following
+commands:
+
+@example
+@group
+# @kbd{cd /usr/lib/grub/i386-pc}
+# @kbd{dd if=stage1 of=/dev/fd0 bs=512 count=1}

+
+The device file name may be different. Consult the manual for your OS.
+
+
+@node Installing GRUB natively
+@section Installing GRUB natively
+
+@strong{Caution:} Installing GRUB's stage1 in this manner will erase the
+normal boot-sector used by an OS.
+
+GRUB can currently boot GNU Mach, Linux, FreeBSD, NetBSD, and OpenBSD
+directly, so using it on a boot sector (the first sector of a
+partition) should be okay. But generally, it would be a good idea to
+back up the first sector of the partition on which you are installing
+GRUB's stage1. This isn't as important if you are installing GRUB on
+the first sector of a hard disk, since it's easy to reinitialize it
+(e.g. by running @samp{FDISK /MBR} from DOS).
+
+If you decide to install GRUB in the native environment, which is
+definitely desirable, you'll need to create a GRUB boot disk, and
+reboot your computer with it. Otherwise, see @ref{Installing GRUB using
+grub-install}.
+
+Once started, GRUB will show the command-line interface
+(@pxref{Command-line interface}). First, set the GRUB's @dfn{root
+device}@footnote{Note that GRUB's root device doesn't necessarily mean
+your OS's root partition; if you need to specify a root partition for
+your OS, add the argument into the command @command{kernel}.} to the
+partition containing the boot directory, like this:
+
+@example
+grub> @kbd{root (hd0,0)}
+@end example
+
+If you are not sure which partition actually holds this directory, use the
+command @command{find} (@pxref{find}), like this:
+
+@example
+grub> @kbd{find /boot/grub/stage1}
+@end example
+
+This will search for the file name @file{/boot/grub/stage1} and show the
+devices which contain the file.
+
+Once you've set the root device correctly, run the command
+@command{setup} (@pxref{setup}):
+
+@example
+grub> @kbd{setup (hd0)}
+@end example
+
+This command will install the GRUB boot loader on the Master Boot
+Record (MBR) of the first drive. If you want to put GRUB into the boot
+sector of a partition instead of putting it in the MBR, specify the
+partition into which you want to install GRUB:
+
+@example
+grub> @kbd{setup (hd0,0)}
+@end example
+
+If you install GRUB into a partition or a drive other than the first
+one, you must chain-load GRUB from another boot loader. Refer to the
+manual for the boot loader to know how to chain-load GRUB.
+
+After using the setup command, you will boot into GRUB without the
+GRUB floppy. See the chapter @ref{Booting} to find out how to boot
+your operating systems from GRUB.
+
+
+@node Installing GRUB using grub-install
+@section Installing GRUB using grub-install
+
+@strong{Caution:} This procedure is definitely less safe, because
+there are several ways in which your computer can become
+unbootable. For example, most operating systems don't tell GRUB how to
+map BIOS drives to OS devices correctly---GRUB merely @dfn{guesses}
+the mapping. This will succeed in most cases, but not
+always. Therefore, GRUB provides you with a map file called the
+@dfn{device map}, which you must fix if it is wrong. @xref{Device
+map}, for more details.
+
+If you still do want to install GRUB under a UNIX-like OS (such
+as @sc{gnu}), invoke the program @command{grub-install} (@pxref{Invoking
+grub-install}) as the superuser (@dfn{root}).
+
+The usage is basically very simple. You only need to specify one
+argument to the program, namely, where to install the boot loader. The
+argument can be either a device file (like @samp{/dev/hda}) or a
+partition specified in GRUB's notation. For example, under Linux the
+following will install GRUB into the MBR of the first IDE disk:
+
+@example
+# @kbd{grub-install /dev/hda}
+@end example
+
+Likewise, under GNU/Hurd, this has the same effect:
+
+@example
+# @kbd{grub-install /dev/hd0}
+@end example
+
+If it is the first BIOS drive, this is the same as well:
+
+@example
+# @kbd{grub-install '(hd0)'}
+@end example
+
+Or you can omit the parentheses:
+
+@example
+# @kbd{grub-install hd0}
+@end example
+
+But all the above examples assume that GRUB should use images under
+the root directory. If you want GRUB to use images under a directory
+other than the root directory, you need to specify the option
+@option{--root-directory}. The typical usage is that you create a GRUB
+boot floppy with a filesystem. Here is an example:
+
+@example
+@group
+# @kbd{mke2fs /dev/fd0}
+# @kbd{mount -t ext2 /dev/fd0 /mnt}
+# @kbd{grub-install --root-directory=/mnt fd0}
+# @kbd{umount /mnt}
+@end group
+@end example
+
+Another example is when you have a separate boot partition
+which is mounted at @file{/boot}. Since GRUB is a boot loader, it
+doesn't know anything about mountpoints at all. Thus, you need to run
+@command{grub-install} like this:
+
+@example
+# @kbd{grub-install --root-directory=/boot /dev/hda}
+@end example
+
+By the way, as noted above, it is quite difficult to guess BIOS drives
+correctly under a UNIX-like OS. Thus, @command{grub-install} will prompt
+you to check if it could really guess the correct mappings, after the
+installation. The format is defined in @ref{Device map}. Please be
+quite careful. If the output is wrong, it is unlikely that your
+computer will be able to boot with no problem.
+
+Note that @command{grub-install} is actually just a shell script and the
+real task is done by the grub shell @command{grub} (@pxref{Invoking the
+grub shell}). Therefore, you may run @command{grub} directly to install
+GRUB, without using @command{grub-install}. Don't do that, however,
+unless you are very familiar with the internals of GRUB. Installing a
+boot loader on a running OS may be extremely dangerous.
+
+
+@node Making a GRUB bootable CD-ROM
+@section Making a GRUB bootable CD-ROM
+
+GRUB supports the @dfn{no emulation mode} in the El Torito
+specification@footnote{El Torito is a specification for bootable CD
+using BIOS functions.}. This means that you can use the whole CD-ROM
+from GRUB and you don't have to make a floppy or hard disk image file,
+which can cause compatibility problems.
+
+For booting from a CD-ROM, GRUB uses a special Stage 2 called
+@file{stage2_eltorito}. The only GRUB files you need to have in your
+bootable CD-ROM are this @file{stage2_eltorito} and optionally a config file
+@file{menu.lst}. You don't need to use @file{stage1} or @file{stage2},
+because El Torito is quite different from the standard boot process.
+
+Here is an example of procedures to make a bootable CD-ROM
+image. First, make a top directory for the bootable image, say,
+@samp{iso}:
+
+@example
+$ @kbd{mkdir iso}
+@end example
+
+Make a directory for GRUB:
+
+@example
+$ @kbd{mkdir -p iso/boot/grub}
+@end example
+
+Copy the file @file{stage2_eltorito}:
+
+@example
+$ @kbd{cp /usr/lib/grub/i386-pc/stage2_eltorito iso/boot/grub}
+@end example
+
+If desired, make the config file @file{menu.lst} under @file{iso/boot/grub}
+(@pxref{Configuration}), and copy any files and directories for the disc to the
+directory @file{iso/}.
+
+Finally, make a ISO9660 image file like this:
+
+@example
+$ @kbd{mkisofs -R -b boot/grub/stage2_eltorito -no-emul-boot \
+ -boot-load-size 4 -boot-info-table -o grub.iso iso}
+@end example
+
+This produces a file named @file{grub.iso}, which then can be burned
+into a CD (or a DVD). @kbd{mkisofs} has already set up the disc to boot
+from the @kbd{boot/grub/stage2_eltorito} file, so there is no need to
+setup GRUB on the disc. (Note that the @kbd{-boot-load-size 4} bit is
+required for compatibility with the BIOS on many older machines.)
+
+You can use the device @samp{(cd)} to access a CD-ROM in your
+config file. This is not required; GRUB automatically sets the root device
+to @samp{(cd)} when booted from a CD-ROM. It is only necessary to refer to
+@samp{(cd)} if you want to access other drives as well.

+GRUB has two distinct boot methods. One of the two is to load an

+loader which then will load an operating system actually. Generally
+speaking, the former is more desirable, because you don't need to
+install or maintain other boot loaders and GRUB is flexible enough to
+load an operating system from an arbitrary disk/partition. However,
+the latter is sometimes required, since GRUB doesn't support all the
+existing operating systems natively.

+@node Loading an operating system directly
+@subsection How to boot an OS directly with GRUB
+
+Multiboot (@pxref{Top, Multiboot Specification, Motivation, multiboot,

+For the sake of convenience, there is also support for Linux, FreeBSD,
+NetBSD and OpenBSD. If you want to boot other operating systems, you
+will have to chain-load them (@pxref{Chain-loading}).
+
+Generally, GRUB can boot any Multiboot-compliant OS in the following
+steps:
+
+@enumerate
+@item
+Set GRUB's root device to the drive where the OS images are stored with
+the command @command{root} (@pxref{root}).

+@end enumerate
+
+Linux, FreeBSD, NetBSD and OpenBSD can be booted in a similar
+manner. You load a kernel image with the command @command{kernel} and

+GRUB cannot boot DOS or Windows directly, so you must chain-load them
+(@pxref{Chain-loading}). However, their boot loaders have some critical
+deficiencies, so it may not work to just chain-load them. To overcome
+the problems, GRUB provides you with two helper functions.
+
+If you have installed DOS (or Windows) on a non-first hard disk, you
+have to use the disk swapping technique, because that OS cannot boot
+from any disks but the first one. The workaround used in GRUB is the
+command @command{map} (@pxref{map}), like this:
+
+@example
+@group
+grub> @kbd{map (hd0) (hd1)}
+grub> @kbd{map (hd1) (hd0)}
+@end group
+@end example
+
+This performs a @dfn{virtual} swap between your first and second hard
+drive.
+
+@strong{Caution:} This is effective only if DOS (or Windows) uses BIOS
+to access the swapped disks. If that OS uses a special driver for the
+disks, this probably won't work.
+
+Another problem arises if you installed more than one set of DOS/Windows
+onto one disk, because they could be confused if there are more than one
+primary partitions for DOS/Windows. Certainly you should avoid doing
+this, but there is a solution if you do want to do so. Use the partition
+hiding/unhiding technique.
+
+If GRUB @dfn{hide}s a DOS (or Windows) partition (@pxref{hide}), DOS (or
+Windows) will ignore the partition. If GRUB @dfn{unhide}s a DOS (or
+Windows) partition (@pxref{unhide}), DOS (or Windows) will detect the
+partition. Thus, if you have installed DOS (or Windows) on the first
+and the second partition of the first hard disk, and you want to boot
+the copy on the first partition, do the following:
+
+@example
+@group
+grub> @kbd{unhide (hd0,0)}

+@node Making your system robust
+@section How to make your system robust
+
+When you test a new kernel or a new OS, it is important to make sure
+that your computer can boot even if the new system is unbootable. This
+is crucial especially if you maintain servers or remote systems. To
+accomplish this goal, you need to set up two things:
+
+@enumerate
+@item
+You must maintain a system which is always bootable. For instance, if
+you test a new kernel, you need to keep a working kernel in a
+different place. And, it would sometimes be very nice to even have a
+complete copy of a working system in a different partition or disk.
+
+@item
+You must direct GRUB to boot a working system when the new system
+fails. This is possible with the @dfn{fallback} system in GRUB.
+@end enumerate
+
+The former requirement is very specific to each OS, so this
+documentation does not cover that topic. It is better to consult some
+backup tools.
+
+So let's see the GRUB part. There are two possibilities: one of them
+is quite simple but not very robust, and the other is a bit complex to
+set up but probably the best solution to make sure that your system
+can start as long as GRUB itself is bootable.

+@subsection Booting once-only
+
+You can teach GRUB to boot an entry only at next boot time. Suppose
+that your have an old kernel @file{old_kernel} and a new kernel
+@file{new_kernel}. You know that @file{old_kernel} can boot
+your system correctly, and you want to test @file{new_kernel}.
+
+To ensure that your system will go back to the old kernel even if the
+new kernel fails (e.g. it panics), you can specify that GRUB should
+try the new kernel only once and boot the old kernel after that.
+
+First, modify your configuration file. Here is an example:
+
+@example
+@group
+default saved # This is important!!!
+timeout 10
+
+title the old kernel
+root (hd0,0)
+kernel /old_kernel
+savedefault
+
+title the new kernel
+root (hd0,0)
+kernel /new_kernel
+savedefault 0 # This is important!!!
+@end group
+@end example
+
+Note that this configuration file uses @samp{default saved}
+(@pxref{default}) at the head and @samp{savedefault 0}
+(@pxref{savedefault}) in the entry for the new kernel. This means
+that GRUB boots a saved entry by default, and booting the entry for the
+new kernel saves @samp{0} as the saved entry.
+
+With this configuration file, after all, GRUB always tries to boot the
+old kernel after it booted the new one, because @samp{0} is the entry
+of @code{the old kernel}.
+
+The next step is to tell GRUB to boot the new kernel at next boot
+time. For this, execute @command{grub-set-default} (@pxref{Invoking
+grub-set-default}):
+
+@example
+# @kbd{grub-set-default 1}
+@end example
+
+This command sets the saved entry to @samp{1}, that is, to the new
+kernel.
+
+This method is useful, but still not very robust, because GRUB stops
+booting, if there is any error in the boot entry, such that the new
+kernel has an invalid executable format. Thus, it it even better to
+use the @dfn{fallback} mechanism of GRUB. Look at next subsection for
+this feature.
+
+
+@node Booting fallback systems
+@subsection Booting fallback systems
+
+GRUB supports a fallback mechanism of booting one or more other
+entries if a default boot entry fails. You can specify multiple
+fallback entries if you wish.
+
+Suppose that you have three systems, @samp{A}, @samp{B} and
+@samp{C}. @samp{A} is a system which you want to boot by
+default. @samp{B} is a backup system which is supposed to boot
+safely. @samp{C} is another backup system which is used in case where
+@samp{B} is broken.
+
+Then you may want GRUB to boot the first system which is bootable
+among @samp{A}, @samp{B} and @samp{C}. A configuration file can be
+written in this way:
+
+@example
+@group
+default saved # This is important!!!
+timeout 10
+fallback 1 2 # This is important!!!
+
+title A
+root (hd0,0)
+kernel /kernel
+savedefault fallback # This is important!!!
+
+title B
+root (hd1,0)
+kernel /kernel
+savedefault fallback # This is important!!!
+
+title C
+root (hd2,0)
+kernel /kernel
+savedefault
+@end group
+@end example
+
+Note that @samp{default saved} (@pxref{default}), @samp{fallback 1 2}
+and @samp{savedefault fallback} are used. GRUB will boot a saved entry
+by default and save a fallback entry as next boot entry with this
+configuration.
+
+When GRUB tries to boot @samp{A}, GRUB saves @samp{1} as next boot
+entry, because the command @command{fallback} specifies that @samp{1}
+is the first fallback entry. The entry @samp{1} is @samp{B}, so GRUB
+will try to boot @samp{B} at next boot time.
+
+Likewise, when GRUB tries to boot @samp{B}, GRUB saves @samp{2} as
+next boot entry, because @command{fallback} specifies @samp{2} as next
+fallback entry. This makes sure that GRUB will boot @samp{C} after
+booting @samp{B}.
+
+It is noteworthy that GRUB uses fallback entries both when GRUB
+itself fails in booting an entry and when @samp{A} or @samp{B} fails
+in starting up your system. So this solution ensures that your system
+is started even if GRUB cannot find your kernel or if your kernel
+panics.
+
+However, you need to run @command{grub-set-default} (@pxref{Invoking
+grub-set-default}) when @samp{A} starts correctly or you fix @samp{A}
+after it crashes, since GRUB always sets next boot entry to a fallback
+entry. You should run this command in a startup script such as
+@file{rc.local} to boot @samp{A} by default:
+
+@example
+# @kbd{grub-set-default 0}
+@end example
+
+where @samp{0} is the number of the boot entry for the system
+@samp{A}.
+
+If you want to see what is current default entry, you can look at the
+file @file{/boot/grub/default} (or @file{/grub/default} in
+some systems). Because this file is plain-text, you can just
+@command{cat} this file. But it is strongly recommended @strong{not to
+modify this file directly}, because GRUB may fail in saving a default
+entry in this file, if you change this file in an unintended
+manner. Therefore, you should use @command{grub-set-default} when you
+need to change the default entry.
+
+
+@node Configuration
+@chapter Configuration
+
+You've probably noticed that you need to type several commands to boot your
+OS. There's a solution to that - GRUB provides a menu interface
+(@pxref{Menu interface}) from which you can select an item (using arrow
+keys) that will do everything to boot an OS.
+
+To enable the menu, you need a configuration file,
+@file{menu.lst} under the boot directory. We'll analyze an example
+file.
+
+The file first contains some general settings, the menu interface
+related options. You can put these commands (@pxref{Menu-specific
+commands}) before any of the items (starting with @command{title}
+(@pxref{title})).
+
+@example
+@group
+#
+# Sample boot menu configuration file
+#
+@end group
+@end example
+
+As you may have guessed, these lines are comments. Lines starting with a
+hash character (@samp{#}), and blank lines, are ignored by GRUB.
+
+@example
+@group
+# By default, boot the first entry.
+default 0
+@end group
+@end example
+
+The first entry (here, counting starts with number zero, not one!) will
+be the default choice.
+
+@example
+@group
+# Boot automatically after 30 secs.
+timeout 30
+@end group
+@end example
+
+As the comment says, GRUB will boot automatically in 30 seconds, unless
+interrupted with a keypress.
+
+@example
+@group
+# Fallback to the second entry.
+fallback 1
+@end group
+@end example
+
+If, for any reason, the default entry doesn't work, fall back to the
+second one (this is rarely used, for obvious reasons).
+
+Note that the complete descriptions of these commands, which are menu
+interface specific, can be found in @ref{Menu-specific
+commands}. Other descriptions can be found in @ref{Commands}.
+
+Now, on to the actual OS definitions. You will see that each entry
+begins with a special command, @command{title} (@pxref{title}), and the
+action is described after it. Note that there is no command
+@command{boot} (@pxref{boot}) at the end of each item. That is because
+GRUB automatically executes @command{boot} if it loads other commands
+successfully.
+
+The argument for the command @command{title} is used to display a short
+title/description of the entry in the menu. Since @command{title}
+displays the argument as is, you can write basically anything there.
+
+@example
+@group
+# For booting GNU/Hurd
+title GNU/Hurd
+root (hd0,0)
+kernel /boot/gnumach.gz root=hd0s1
+module /boot/serverboot.gz
+@end group
+@end example
+
+This boots GNU/Hurd from the first hard disk.
+
+@example
+@group
+# For booting GNU/Linux
+title GNU/Linux
+kernel (hd1,0)/vmlinuz root=/dev/hdb1
+@end group
+@end example
+
+This boots GNU/Linux, but from the second hard disk.
+
+@example
+@group
+# For booting Mach (getting kernel from floppy)
+title Utah Mach4 multiboot
+root (hd0,2)
+pause Insert the diskette now^G!!
+kernel (fd0)/boot/kernel root=hd0s3
+module (fd0)/boot/bootstrap
+@end group
+@end example
+
+This boots Mach with a kernel on a floppy, but the root filesystem at
+hd0s3. It also contains a @command{pause} line (@pxref{pause}), which
+will cause GRUB to display a prompt and delay, before actually executing
+the rest of the commands and booting.
+
+@example
+@group
+# For booting FreeBSD
+title FreeBSD
+root (hd0,2,a)
+kernel /boot/loader
+@end group
+@end example
+
+This item will boot FreeBSD kernel loaded from the @samp{a} partition of
+the third @sc{pc} slice of the first hard disk.
+
+@example
+@group
+# For booting OS/2
+title OS/2
+root (hd0,1)
+makeactive
+# chainload OS/2 bootloader from the first sector
+chainloader +1
+# This is similar to "chainload", but loads a specific file
+#chainloader /boot/chain.os2
+@end group
+@end example
+
+This will boot OS/2, using a chain-loader (@pxref{Chain-loading}).
+
+@example
+@group
+# For booting Windows NT or Windows95
+title Windows NT / Windows 95 boot menu
+root (hd0,0)
+makeactive
+chainloader +1
+# For loading DOS if Windows NT is installed
+# chainload /bootsect.dos
+@end group
+@end example
+
+The same as the above, but for Windows.
+
+@example
+@group
+# For installing GRUB into the hard disk
+title Install GRUB into the hard disk
+root (hd0,0)
+setup (hd0)
+@end group
+@end example
+
+This will just (re)install GRUB onto the hard disk.
+
+@example
+# Change the colors.
+title Change the colors
+color light-green/brown blink-red/blue
+@end example
+
+In the last entry, the command @command{color} is used (@pxref{color}),
+to change the menu colors (try it!). This command is somewhat special,
+because it can be used both in the command-line and in the menu. GRUB
+has several such commands, see @ref{General commands}.
+
+We hope that you now understand how to use the basic features of
+GRUB. To learn more about GRUB, see the following chapters.
+
+
+@node Network
+@chapter Downloading OS images from a network
+
+Although GRUB is a disk-based boot loader, it does provide network
+support. To use the network support, you need to enable at least one
+network driver in the GRUB build process. For more information please
+see @file{netboot/README.netboot} in the source distribution.
+
+@menu
+* General usage of network support::
+* Diskless::
+@end menu
+
+
+@node General usage of network support
+@section How to set up your network
+
+GRUB requires a file server and optionally a server that will assign an
+IP address to the machine on which GRUB is running. For the former, only
+TFTP is supported at the moment. The latter is either BOOTP, DHCP or a
+RARP server@footnote{RARP is not advised, since it cannot serve much
+information}. It is not necessary to run both the servers on one
+computer. How to configure these servers is beyond the scope of this
+document, so please refer to the manuals specific to those
+protocols/servers.
+
+If you decided to use a server to assign an IP address, set up the
+server and run @command{bootp} (@pxref{bootp}), @command{dhcp}
+(@pxref{dhcp}) or @command{rarp} (@pxref{rarp}) for BOOTP, DHCP or RARP,
+respectively. Each command will show an assigned IP address, a netmask,
+an IP address for your TFTP server and a gateway. If any of the
+addresses is wrong or it causes an error, probably the configuration of
+your servers isn't set up properly.
+
+Otherwise, run @command{ifconfig}, like this:
+
+@example
+grub> @kbd{ifconfig --address=192.168.110.23 --server=192.168.110.14}
+@end example
+
+You can also use @command{ifconfig} in conjuction with @command{bootp},
+@command{dhcp} or @command{rarp} (e.g. to reassign the server address
+manually). @xref{ifconfig}, for more details.
+
+Finally, download your OS images from your network. The network can be
+accessed using the network drive @samp{(nd)}. Everything else is very
+similar to the normal instructions (@pxref{Booting}).
+
+Here is an example:
+
+@example
+@group
+grub> @kbd{bootp}
+Probing... [NE*000]
+NE2000 base ...
+Address: 192.168.110.23 Netmask: 255.255.255.0
+Server: 192.168.110.14 Gateway: 192.168.110.1
+
+grub> @kbd{root (nd)}
+grub> @kbd{kernel /tftproot/gnumach.gz root=sd0s1}
+grub> @kbd{module /tftproot/serverboot.gz}
+grub> @kbd{boot}
+@end group
+@end example
+
+
+@node Diskless
+@section Booting from a network
+
+It is sometimes very useful to boot from a network, especially when you
+use a machine which has no local disk. In this case, you need to obtain
+a kind of Net Boot @sc{rom}, such as a PXE @sc{rom} or a free software
+package like Etherboot. Such a Boot @sc{rom} first boots the machine,
+sets up the network card installed into the machine, and downloads a
+second stage boot image from the network. Then, the second image will
+try to boot an operating system actually from the network.
+
+GRUB provides two second stage images, @file{nbgrub} and
+@file{pxegrub} (@pxref{Images}). These images are the same as the
+normal Stage 2, except that they set up a network automatically, and try
+to load a configuration file from the network, if specified. The usage
+is very simple: If the machine has a PXE @sc{rom}, use
+@file{pxegrub}. If the machine has an NBI loader such as Etherboot, use
+@file{nbgrub}. There is no difference between them except their
+formats. Since the way to load a second stage image you want to use
+should be described in the manual on your Net Boot @sc{rom}, please
+refer to the manual, for more information.
+
+However, there is one thing specific to GRUB. Namely, how to specify a
+configuration file in a BOOTP/DHCP server. For now, GRUB uses the tag
+@samp{150}, to get the name of a configuration file. The following is an
+example with a BOOTP configuration:
+
+@example
+@group
+.allhost:hd=/tmp:bf=null:\
+ :ds=145.71.35.1 145.71.32.1:\
+ :sm=255.255.254.0:\
+ :gw=145.71.35.1:\
+ :sa=145.71.35.5:
+
+foo:ht=1:ha=63655d0334a7:ip=145.71.35.127:\
+ :bf=/nbgrub:\
+ :tc=.allhost:\
+ :T150="(nd)/tftpboot/menu.lst.foo":
+@end group
+@end example
+
+Note that you should specify the drive name @code{(nd)} in the name of
+the configuration file. This is because you might change the root drive
+before downloading the configuration from the TFTP server when the
+preset menu feature is used (@pxref{Preset Menu}).
+
+See the manual of your BOOTP/DHCP server for more information. The
+exact syntax should differ a little from the example.
+
+
+@node Serial terminal
+@chapter Using GRUB via a serial line
+
+This chapter describes how to use the serial terminal support in GRUB.
+
+If you have many computers or computers with no display/keyboard, it
+could be very useful to control the computers through serial
+communications. To connect one computer with another via a serial line,
+you need to prepare a null-modem (cross) serial cable, and you may need
+to have multiport serial boards, if your computer doesn't have extra
+serial ports. In addition, a terminal emulator is also required, such as
+minicom. Refer to a manual of your operating system, for more
+information.
+
+As for GRUB, the instruction to set up a serial terminal is quite
+simple. First of all, make sure that you haven't specified the option
+@option{--disable-serial} to the configure script when you built your
+GRUB images. If you get them in binary form, probably they have serial
+terminal support already.
+
+Then, initialize your serial terminal after GRUB starts up. Here is an
+example:
+
+@example
+@group
+grub> @kbd{serial --unit=0 --speed=9600}
+grub> @kbd{terminal serial}
+@end group
+@end example
+
+The command @command{serial} initializes the serial unit 0 with the
+speed 9600bps. The serial unit 0 is usually called @samp{COM1}, so, if
+you want to use COM2, you must specify @samp{--unit=1} instead. This
+command accepts many other options, so please refer to @ref{serial},
+for more details.
+
+The command @command{terminal} (@pxref{terminal}) chooses which type of
+terminal you want to use. In the case above, the terminal will be a
+serial terminal, but you can also pass @code{console} to the command,
+as @samp{terminal serial console}. In this case, a terminal in which
+you press any key will be selected as a GRUB terminal.
+
+However, note that GRUB assumes that your terminal emulator is
+compatible with VT100 by default. This is true for most terminal
+emulators nowadays, but you should pass the option @option{--dumb} to
+the command if your terminal emulator is not VT100-compatible or
+implements few VT100 escape sequences. If you specify this option then
+GRUB provides you with an alternative menu interface, because the normal
+menu requires several fancy features of your terminal.
+
+
+@node Preset Menu
+@chapter Embedding a configuration file into GRUB
+
+GRUB supports a @dfn{preset menu} which is to be always loaded before
+starting. The preset menu feature is useful, for example, when your
+computer has no console but a serial cable. In this case, it is
+critical to set up the serial terminal as soon as possible, since you
+cannot see any message until the serial terminal begins to work. So it
+is good to run the commands @command{serial} (@pxref{serial}) and
+@command{terminal} (@pxref{terminal}) before anything else at the
+start-up time.
+
+How the preset menu works is slightly complicated:
+
+@enumerate
+@item
+GRUB checks if the preset menu feature is used, and loads the preset
+menu, if available. This includes running commands and reading boot
+entries, like an ordinary configuration file.
+
+@item
+GRUB checks if the configuration file is available. Note that this check
+is performed @strong{regardless of the existence of the preset
+menu}. The configuration file is loaded even if the preset menu was
+loaded.
+
+@item
+If the preset menu includes any boot entries, they are cleared when
+the configuration file is loaded. It doesn't matter whether the
+configuration file has any entries or no entry. The boot entries in the
+preset menu are used only when GRUB fails in loading the configuration
+file.
+@end enumerate
+
+To enable the preset menu feature, you must rebuild GRUB specifying a
+file to the configure script with the option
+@option{--enable-preset-menu}. The file has the same semantics as
+normal configuration files (@pxref{Configuration}).
+
+Another point you should take care is that the diskless support
+(@pxref{Diskless}) diverts the preset menu. Diskless images embed a
+preset menu to execute the command @command{bootp} (@pxref{bootp})
+automatically, unless you specify your own preset menu to the configure
+script. This means that you must put commands to initialize a network in
+the preset menu yourself, because diskless images don't set it up
+implicitly, when you use the preset menu explicitly.
+
+Therefore, a typical preset menu used with diskless support would be
+like this:
+
+@example
+@group
+# Set up the serial terminal, first of all.
+serial --unit=0 --speed=19200
+terminal --timeout=0 serial
+
+# Initialize the network.
+dhcp
+@end group
+@end example
+
+
+@node Security
+@chapter Protecting your computer from cracking
+
+You may be interested in how to prevent ordinary users from doing
+whatever they like, if you share your computer with other people. So
+this chapter describes how to improve the security of GRUB.
+
+One thing which could be a security hole is that the user can do too
+many things with GRUB, because GRUB allows one to modify its configuration
+and run arbitrary commands at run-time. For example, the user can even
+read @file{/etc/passwd} in the command-line interface by the command
+@command{cat} (@pxref{cat}). So it is necessary to disable all the
+interactive operations.
+
+Thus, GRUB provides a @dfn{password} feature, so that only administrators
+can start the interactive operations (i.e. editing menu entries and
+entering the command-line interface). To use this feature, you need to
+run the command @command{password} in your configuration file
+(@pxref{password}), like this:
+
+@example
+password --md5 PASSWORD
+@end example
+
+If this is specified, GRUB disallows any interactive control, until you
+press the key @key{p} and enter a correct password. The option
+@option{--md5} tells GRUB that @samp{PASSWORD} is in MD5 format. If it
+is omitted, GRUB assumes the @samp{PASSWORD} is in clear text.
+
+You can encrypt your password with the command @command{md5crypt}
+(@pxref{md5crypt}). For example, run the grub shell (@pxref{Invoking the
+grub shell}), and enter your password:
+
+@example
+@group
+grub> md5crypt
+Password: **********
+Encrypted: $1$U$JK7xFegdxWH6VuppCUSIb.
+@end group
+@end example
+
+Then, cut and paste the encrypted password to your configuration file.
+
+Also, you can specify an optional argument to @command{password}. See
+this example:
+
+@example
+password PASSWORD /boot/grub/menu-admin.lst
+@end example
+
+In this case, GRUB will load @file{/boot/grub/menu-admin.lst} as a
+configuration file when you enter the valid password.
+
+Another thing which may be dangerous is that any user can choose any
+menu entry. Usually, this wouldn't be problematic, but you might want to
+permit only administrators to run some of your menu entries, such as an
+entry for booting an insecure OS like DOS.
+
+GRUB provides the command @command{lock} (@pxref{lock}). This command
+always fails until you enter the valid password, so you can use it, like
+this:
+
+@example
+@group
+title Boot DOS
+lock
+rootnoverify (hd0,1)
+makeactive
+chainload +1
+@end group
+@end example
+
+You should insert @command{lock} right after @command{title}, because
+any user can execute commands in an entry until GRUB encounters
+@command{lock}.
+
+You can also use the command @command{password} instead of
+@command{lock}. In this case the boot process will ask for the password
+and stop if it was entered incorrectly. Since the @command{password}
+takes its own @var{PASSWORD} argument this is useful if you want
+different passwords for different entries.
+
+
+@node Images
+@chapter GRUB image files
+
+GRUB consists of several images: two essential stages, optional stages
+called @dfn{Stage 1.5}, one image for bootable CD-ROM, and two network
+boot images. Here is a short overview of them. @xref{Internals}, for
+more details.
+
+@table @file
+@item stage1
+This is an essential image used for booting up GRUB. Usually, this is
+embedded in an MBR or the boot sector of a partition. Because a PC boot
+sector is 512 bytes, the size of this image is exactly 512 bytes.
+
+All @file{stage1} must do is to load Stage 2 or Stage 1.5 from a local
+disk. Because of the size restriction, @file{stage1} encodes the
+location of Stage 2 (or Stage 1.5) in a block list format, so it never
+understand any filesystem structure.
+
+@item stage2
+This is the core image of GRUB. It does everything but booting up
+itself. Usually, this is put in a filesystem, but that is not required.
+
+@item e2fs_stage1_5
+@itemx fat_stage1_5
+@itemx ffs_stage1_5
+@itemx jfs_stage1_5
+@itemx minix_stage1_5
+@itemx reiserfs_stage1_5
+@itemx vstafs_stage1_5
+@itemx xfs_stage1_5
+
+These are called @dfn{Stage 1.5}, because they serve as a bridge
+between @file{stage1} and @file{stage2}, that is to say, Stage 1.5 is
+loaded by Stage 1 and Stage 1.5 loads Stage 2. The difference between
+@file{stage1} and @file{*_stage1_5} is that the former doesn't
+understand any filesystem while the latter understands one filesystem
+(e.g. @file{e2fs_stage1_5} understands ext2fs). So you can move the
+Stage 2 image to another location safely, even after GRUB has been
+installed.
+
+While Stage 2 cannot generally be embedded in a fixed area as the size
+is so large, Stage 1.5 can be installed into the area right after an MBR,
+or the boot loader area of a ReiserFS or a FFS.
+
+@item stage2_eltorito
+This is a boot image for CD-ROMs using the @dfn{no emulation mode} in
+El Torito specification. This is identical to Stage 2, except that
+this boots up without Stage 1 and sets up a special drive @samp{(cd)}.
+
+@item nbgrub
+This is a network boot image for the Network Image Proposal used by some
+network boot loaders, such as Etherboot. This is mostly the same as
+Stage 2, but it also sets up a network and loads a configuration file
+from the network.
+
+@item pxegrub
+This is another network boot image for the Preboot Execution Environment
+used by several Netboot ROMs. This is identical to @file{nbgrub}, except
+for the format.
+@end table
+
+
+@node Filesystem
+@chapter Filesystem syntax and semantics
+
+GRUB uses a special syntax for specifying disk drives which can be
+accessed by BIOS. Because of BIOS limitations, GRUB cannot distinguish
+between IDE, ESDI, SCSI, or others. You must know yourself which BIOS
+device is equivalent to which OS device. Normally, that will be clear if
+you see the files in a device or use the command @command{find}
+(@pxref{find}).

+@section How to specify devices
+
+The device syntax is like this:
+
+@example
+@code{(@var{device}[,@var{part-num}][,@var{bsd-subpart-letter}])}
+@end example
+
+@samp{[]} means the parameter is optional. @var{device} should be
+either @samp{fd} or @samp{hd} followed by a digit, like @samp{fd0}.
+But you can also set @var{device} to a hexadecimal or a decimal number
+which is a BIOS drive number, so the following are equivalent:
+
+@example
+(hd0)
+(0x80)
+(128)
+@end example
+
+@var{part-num} represents the partition number of @var{device}, starting
+from zero for primary partitions and from four for extended partitions,
+and @var{bsd-subpart-letter} represents the BSD disklabel subpartition,
+such as @samp{a} or @samp{e}.
+
+A shortcut for specifying BSD subpartitions is
+@code{(@var{device},@var{bsd-subpart-letter})}, in this case, GRUB
+searches for the first PC partition containing a BSD disklabel, then
+finds the subpartition @var{bsd-subpart-letter}. Here is an example:
+
+@example
+(hd0,a)
+@end example
+
+The syntax @samp{(hd0)} represents using the entire disk (or the
+MBR when installing GRUB), while the syntax @samp{(hd0,0)}
+represents using the first partition of the disk (or the boot sector
+of the partition when installing GRUB).
+
+If you enabled the network support, the special drive, @samp{(nd)}, is
+also available. Before using the network drive, you must initialize the
+network. @xref{Network}, for more information.
+
+If you boot GRUB from a CD-ROM, @samp{(cd)} is available. @xref{Making
+a GRUB bootable CD-ROM}, for details.
+
+
+@node File name syntax
+@section How to specify files
+
+There are two ways to specify files, by @dfn{absolute file name} and by
+@dfn{block list}.
+
+An absolute file name resembles a Unix absolute file name, using
+@samp{/} for the directory separator (not @samp{\} as in DOS). One
+example is @samp{(hd0,0)/boot/grub/menu.lst}. This means the file
+@file{/boot/grub/menu.lst} in the first partition of the first hard
+disk. If you omit the device name in an absolute file name, GRUB uses
+GRUB's @dfn{root device} implicitly. So if you set the root device to,
+say, @samp{(hd1,0)} by the command @command{root} (@pxref{root}), then
+@code{/boot/kernel} is the same as @code{(hd1,0)/boot/kernel}.
+
+
+@node Block list syntax
+@section How to specify block lists
+
+A block list is used for specifying a file that doesn't appear in the
+filesystem, like a chainloader. The syntax is
+@code{[@var{offset}]+@var{length}[,[@var{offset}]+@var{length}]@dots{}}.
+Here is an example:
+
+@example
+@code{0+100,200+1,300+300}
+@end example
+
+This represents that GRUB should read blocks 0 through 99, block 200,
+and blocks 300 through 599. If you omit an offset, then GRUB assumes
+the offset is zero.
+
+Like the file name syntax (@pxref{File name syntax}), if a blocklist
+does not contain a device name, then GRUB uses GRUB's @dfn{root
+device}. So @code{(hd0,1)+1} is the same as @code{+1} when the root
+device is @samp{(hd0,1)}.
+
+
+@node Interface
+@chapter GRUB's user interface
+
+GRUB has both a simple menu interface for choosing preset entries from a
+configuration file, and a highly flexible command-line for performing
+any desired combination of boot commands.
+
+GRUB looks for its configuration file as soon as it is loaded. If one
+is found, then the full menu interface is activated using whatever
+entries were found in the file. If you choose the @dfn{command-line} menu
+option, or if the configuration file was not found, then GRUB drops to
+the command-line interface.
+
+@menu
+* Command-line interface:: The flexible command-line interface
+* Menu interface:: The simple menu interface
+* Menu entry editor:: Editing a menu entry
+* Hidden menu interface:: The hidden menu interface
+@end menu
+
+
+@node Command-line interface
+@section The flexible command-line interface
+
+The command-line interface provides a prompt and after it an editable
+text area much like a command-line in Unix or DOS. Each command is
+immediately executed after it is entered@footnote{However, this
+behavior will be changed in the future version, in a user-invisible
+way.}. The commands (@pxref{Command-line and menu entry commands}) are a
+subset of those available in the configuration file, used with exactly
+the same syntax.
+
+Cursor movement and editing of the text on the line can be done via a
+subset of the functions available in the Bash shell:
+
+@table @key
+@item C-f
+@itemx PC right key
+Move forward one character.
+
+@item C-b
+@itemx PC left key
+Move back one character.
+
+@item C-a
+@itemx HOME
+Move to the start of the line.
+
+@item C-e
+@itemx END
+Move the the end of the line.
+
+@item C-d
+@itemx DEL
+Delete the character underneath the cursor.
+
+@item C-h
+@itemx BS
+Delete the character to the left of the cursor.
+
+@item C-k
+Kill the text from the current cursor position to the end of the line.
+
+@item C-u
+Kill backward from the cursor to the beginning of the line.
+
+@item C-y
+Yank the killed text back into the buffer at the cursor.
+
+@item C-p
+@itemx PC up key
+Move up through the history list.
+
+@item C-n
+@itemx PC down key
+Move down through the history list.
+@end table
+
+When typing commands interactively, if the cursor is within or before
+the first word in the command-line, pressing the @key{TAB} key (or
+@key{C-i}) will display a listing of the available commands, and if the
+cursor is after the first word, the @kbd{@key{TAB}} will provide a
+completion listing of disks, partitions, and file names depending on the
+context. Note that to obtain a list of drives, one must open a
+parenthesis, as @command{root (}.
+
+Note that you cannot use the completion functionality in the TFTP
+filesystem. This is because TFTP doesn't support file name listing for
+the security.
+
+
+@node Menu interface
+@section The simple menu interface
+
+The menu interface is quite easy to use. Its commands are both
+reasonably intuitive and described on screen.
+
+Basically, the menu interface provides a list of @dfn{boot entries} to
+the user to choose from. Use the arrow keys to select the entry of
+choice, then press @key{RET} to run it. An optional timeout is
+available to boot the default entry (the first one if not set), which is
+aborted by pressing any key.
+
+Commands are available to enter a bare command-line by pressing @key{c}
+(which operates exactly like the non-config-file version of GRUB, but
+allows one to return to the menu if desired by pressing @key{ESC}) or to
+edit any of the @dfn{boot entries} by pressing @key{e}.
+
+If you protect the menu interface with a password (@pxref{Security}),
+all you can do is choose an entry by pressing @key{RET}, or press
+@key{p} to enter the password.
+
+
+@node Menu entry editor
+@section Editing a menu entry
+
+The menu entry editor looks much like the main menu interface, but the
+lines in the menu are individual commands in the selected entry instead
+of entry names.
+
+If an @key{ESC} is pressed in the editor, it aborts all the changes made
+to the configuration entry and returns to the main menu interface.
+
+When a particular line is selected, the editor places the user in a
+special version of the GRUB command-line to edit that line. When the
+user hits @key{RET}, GRUB replaces the line in question in the boot
+entry with the changes (unless it was aborted via @key{ESC},
+in which case the changes are thrown away).
+
+If you want to add a new line to the menu entry, press @key{o} if adding
+a line after the current line or press @key{O} if before the current
+line.
+
+To delete a line, hit the key @key{d}. Although GRUB unfortunately
+does not support @dfn{undo}, you can do almost the same thing by just
+returning to the main menu.
+
+
+@node Hidden menu interface
+@section The hidden menu interface
+
+When your terminal is dumb or you request GRUB to hide the menu
+interface explicitly with the command @command{hiddenmenu}
+(@pxref{hiddenmenu}), GRUB doesn't show the menu interface (@pxref{Menu
+interface}) and automatically boots the default entry, unless
+interrupted by pressing @key{ESC}.
+
+When you interrupt the timeout and your terminal is dumb, GRUB falls
+back to the command-line interface (@pxref{Command-line interface}).
+
+
+@node Commands
+@chapter The list of available commands
+
+In this chapter, we list all commands that are available in GRUB.
+
+Commands belong to different groups. A few can only be used in
+the global section of the configuration file (or ``menu''); most
+of them can be entered on the command-line and can be used either
+anywhere in the menu or specifically in the menu entries.
+
+@menu

+@section The list of commands for the menu only
+
+The semantics used in parsing the configuration file are the following:
+
+@itemize @bullet
+@item
+The menu-specific commands have to be used before any others.
+
+@item
+The files @emph{must} be in plain-text format.
+
+@item
+@samp{#} at the beginning of a line in a configuration file means it is
+only a comment.
+
+@item
+Options are separated by spaces.
+
+@item
+All numbers can be either decimal or hexadecimal. A hexadecimal number
+must be preceded by @samp{0x}, and is case-insensitive.
+
+@item
+Extra options or text at the end of the line are ignored unless otherwise
+specified.
+
+@item
+Unrecognized commands are added to the current entry, except before entries
+start, where they are ignored.
+@end itemize
+
+These commands can only be used in the menu:
+
+@menu
+* default:: Set the default entry
+* fallback:: Set the fallback entry
+* hiddenmenu:: Hide the menu interface
+* timeout:: Set the timeout
+* title:: Start a menu entry
+@end menu
+
+
+@node default
+@subsection default
+
+@deffn Command default num
+Set the default entry to the entry number @var{num}. Numbering starts
+from 0, and the entry number 0 is the default if the command is not
+used.
+
+You can specify @samp{saved} instead of a number. In this case, the
+default entry is the entry saved with the command
+@command{savedefault}. @xref{savedefault}, for more information.
+@end deffn
+
+
+@node fallback
+@subsection fallback
+
+@deffn Command fallback num...
+Go into unattended boot mode: if the default boot entry has any errors,
+instead of waiting for the user to do something, immediately start
+over using the @var{num} entry (same numbering as the @code{default}
+command (@pxref{default})). This obviously won't help if the machine was
+rebooted by a kernel that GRUB loaded. You can specify multiple
+fallback entry numbers.
+@end deffn

+@node hiddenmenu
+@subsection hiddenmenu
+
+@deffn Command hiddenmenu
+Don't display the menu. If the command is used, no menu will be
+displayed on the control terminal, and the default entry will be
+booted after the timeout expired. The user can still request the
+menu to be displayed by pressing @key{ESC} before the timeout
+expires. See also @ref{Hidden menu interface}.

+
+@node color
+@subsection color
+
+@deffn Command color normal [highlight]
+Change the menu colors. The color @var{normal} is used for most
+lines in the menu (@pxref{Menu interface}), and the color
+@var{highlight} is used to highlight the line where the cursor
+points. If you omit @var{highlight}, then the inverted color of
+@var{normal} is used for the highlighted line. The format of a color is
+@code{@var{foreground}/@var{background}}. @var{foreground} and
+@var{background} are symbolic color names. A symbolic color name must be
+one of these:
+
+@itemize @bullet

+@subsection device
+
+@deffn Command device drive file
+In the grub shell, specify the file @var{file} as the actual drive for a
+@sc{bios} drive @var{drive}. You can use this command to create a disk
+image, and/or to fix the drives guessed by GRUB when GRUB fails to
+determine them correctly, like this:
+
+@example
+@group
+grub> @kbd{device (fd0) /floppy-image}

+If used in the first section of a menu file, disable all interactive
+editing control (menu entry editor and command-line) and entries
+protected by the command @command{lock}. If the password @var{passwd} is
+entered, it loads the @var{new-config-file} as a new config file and
+restarts the GRUB Stage 2, if @var{new-config-file} is
+specified. Otherwise, GRUB will just unlock the privileged instructions.
+You can also use this command in the script section, in which case it
+will ask for the password, before continuing. The option

+@deffn Command serial [@option{--unit=unit}] [@option{--port=port}] [@option{--speed=speed}] [@option{--word=word}] [@option{--parity=parity}] [@option{--stop=stop}] [@option{--device=dev}]
+Initialize a serial device. @var{unit} is a number in the range 0-3
+specifying which serial port to use; default is 0, which corresponds to
+the port often called COM1. @var{port} is the I/O port where the UART
+is to be found; if specified it takes precedence over @var{unit}.
+@var{speed} is the transmission speed; default is 9600. @var{word} and
+@var{stop} are the number of data bits and stop bits. Data bits must
+be in the range 5-8 and stop bits must be 1 or 2. Default is 8 data
+bits and one stop bit. @var{parity} is one of @samp{no}, @samp{odd},
+@samp{even} and defaults to @samp{no}. The option @option{--device}
+can only be used in the grub shell and is used to specify the
+tty device to be used in the host operating system (@pxref{Invoking the
+grub shell}).
+
+The serial port is not used as a communication channel unless the

+This command is fairly complex, and you should not use this command
+unless you are familiar with GRUB. Use @command{setup} (@pxref{setup})
+instead.
+
+In short, it will perform a full install presuming the Stage 2 or Stage
+1.5@footnote{They're loaded the same way, so we will refer to the Stage
+1.5 as a Stage 2 from now on.} is in its final install location.
+
+In slightly more detail, it will load @var{stage1_file}, validate that
+it is a GRUB Stage 1 of the right version number, install in it a
+blocklist for loading @var{stage2_file} as a Stage 2. If the option
+@option{d} is present, the Stage 1 will always look for the actual
+disk @var{stage2_file} was installed on, rather than using the booting
+drive. The Stage 2 will be loaded at address @var{addr}, which must be
+@samp{0x8000} for a true Stage 2, and @samp{0x2000} for a Stage 1.5. If
+@var{addr} is not present, GRUB will determine the address
+automatically. It then writes the completed Stage 1 to the first block
+of the device @var{dest_dev}. If the options @option{p} or
+@var{config_file} are present, then it reads the first block of stage2,
+modifies it with the values of the partition @var{stage2_file} was found
+on (for @option{p}) or places the string @var{config_file} into the area
+telling the stage2 where to look for a configuration file at boot
+time. Likewise, if @var{real_config_file} is present and
+@var{stage2_file} is a Stage 1.5, then the Stage 2 @var{config_file} is
+patched with the configuration file name @var{real_config_file}. This
+command preserves the DOS BPB (and for hard disks, the partition table)
+of the sector the Stage 1 is to be installed into.
+
+@strong{Caution:} Several buggy BIOSes don't pass a booting drive
+properly when booting from a hard disk drive. Therefore, you will
+unfortunately have to specify the option @option{d}, whether your
+Stage2 resides at the booting drive or not, if you have such a
+BIOS. We know these are defective in this way:
+
+@table @asis
+@item
+Fujitsu LifeBook 400 BIOS version 31J0103A
+
+@item
+HP Vectra XU 6/200 BIOS version GG.06.11
+@end table
+
+@strong{Caution2:} A number of BIOSes don't return a correct LBA support
+bitmap even if they do have the support. So GRUB provides a solution to
+ignore the wrong bitmap, that is, the option @option{--force-lba}. Don't
+use this option if you know that your BIOS doesn't have LBA support.
+
+@strong{Caution3:} You must specify the option @option{--stage2} in the
+grub shell, if you cannot unmount the filesystem where your stage2 file
+resides. The argument should be the file name in your operating system.

+A disk read error happened while trying to read the stage2 or stage1.5.
+
+@item Geom Error
+The location of the stage2 or stage1.5 is not in the portion of the disk
+supported directly by the BIOS read calls. This could occur because the
+BIOS translated geometry has been changed by the user or the disk is
+moved to another machine or controller after installation, or GRUB was

+
+The general way that the Stage 2 handles errors is to abort the

+continue based on the fact that an error occurred or wait for the user to
+deal with the error.
+
+The following is a comprehensive list of error messages for the Stage 2
+(error numbers for the Stage 1.5 are listed before the colon in each
+description):
+
+@table @asis
+@item 1 : Filename must be either an absolute filename or blocklist
+This error is returned if a file name is requested which doesn't fit the
+syntax/rules listed in the @ref{Filesystem}.
+
+@item 2 : Bad file or directory type
+This error is returned if a file requested is not a regular file, but
+something like a symbolic link, directory, or FIFO.
+
+@item 3 : Bad or corrupt data while decompressing file
+This error is returned if the run-length decompression code gets an
+internal error. This is usually from a corrupt file.
+
+@item 4 : Bad or incompatible header in compressed file
+This error is returned if the file header for a supposedly compressed
+file is bad.
+
+@item 5 : Partition table invalid or corrupt
+This error is returned if the sanity checks on the integrity of the
+partition table fail. This is a bad sign.
+
+@item 6 : Mismatched or corrupt version of stage1/stage2
+This error is returned if the install command points to incompatible
+or corrupt versions of the stage1 or stage2. It can't detect corruption
+in general, but this is a sanity check on the version numbers, which
+should be correct.
+
+@item 7 : Loading below 1MB is not supported
+This error is returned if the lowest address in a kernel is below the
+1MB boundary. The Linux zImage format is a special case and can be
+handled since it has a fixed loading address and maximum size.
+
+@item 8 : Kernel must be loaded before booting
+This error is returned if GRUB is told to execute the boot sequence
+without having a kernel to start.
+
+@item 9 : Unknown boot failure
+This error is returned if the boot attempt did not succeed for reasons
+which are unknown.
+
+@item 10 : Unsupported Multiboot features requested
+This error is returned when the Multiboot features word in the Multiboot
+header requires a feature that is not recognized. The point of this is
+that the kernel requires special handling which GRUB is probably
+unable to provide.

+@item 11 : Unrecognized device string
+This error is returned if a device string was expected, and the string
+encountered didn't fit the syntax/rules listed in the @ref{Filesystem}.
+
+@item 12 : Invalid device requested
+This error is returned if a device string is recognizable but does not
+fall under the other device errors.
+
+@item 13 : Invalid or unsupported executable format
+This error is returned if the kernel image being loaded is not
+recognized as Multiboot or one of the supported native formats (Linux
+zImage or bzImage, FreeBSD, or NetBSD).
+
+@item 14 : Filesystem compatibility error, cannot read whole file
+Some of the filesystem reading code in GRUB has limits on the length of
+the files it can read. This error is returned when the user runs into
+such a limit.
+
+@item 15 : File not found
+This error is returned if the specified file name cannot be found, but
+everything else (like the disk/partition info) is OK.
+
+@item 16 : Inconsistent filesystem structure
+This error is returned by the filesystem code to denote an internal
+error caused by the sanity checks of the filesystem structure on disk
+not matching what it expects. This is usually caused by a corrupt
+filesystem or bugs in the code handling it in GRUB.
+
+@item 17 : Cannot mount selected partition
+This error is returned if the partition requested exists, but the
+filesystem type cannot be recognized by GRUB.
+
+@item 18 : Selected cylinder exceeds maximum supported by BIOS
+This error is returned when a read is attempted at a linear block
+address beyond the end of the BIOS translated area. This generally
+happens if your disk is larger than the BIOS can handle (512MB for
+(E)IDE disks on older machines or larger than 8GB in general).
+
+@item 19 : Linux kernel must be loaded before initrd
+This error is returned if the initrd command is used before loading a
+Linux kernel.
+
+@item 20 : Multiboot kernel must be loaded before modules
+This error is returned if the module load command is used before loading
+a Multiboot kernel. It only makes sense in this case anyway, as GRUB has
+no idea how to communicate the presence of such modules to a
+non-Multiboot-aware kernel.
+
+@item 21 : Selected disk does not exist
+This error is returned if the device part of a device- or full file name
+refers to a disk or BIOS device that is not present or not recognized by
+the BIOS in the system.
+
+@item 22 : No such partition
+This error is returned if a partition is requested in the device part of
+a device- or full file name which isn't on the selected disk.
+
+@item 23 : Error while parsing number
+This error is returned if GRUB was expecting to read a number and
+encountered bad data.
+
+@item 24 : Attempt to access block outside partition
+This error is returned if a linear block address is outside of the disk
+partition. This generally happens because of a corrupt filesystem on the
+disk or a bug in the code handling it in GRUB (it's a great debugging
+tool).
+
+@item 25 : Disk read error
+This error is returned if there is a disk read error when trying to
+probe or read data from a particular disk.
+
+@item 26 : Too many symbolic links
+This error is returned if the link count is beyond the maximum
+(currently 5), possibly the symbolic links are looped.
+
+@item 27 : Unrecognized command
+This error is returned if an unrecognized command is entered on the
+command-line or in a boot sequence section of a configuration file and
+that entry is selected.
+
+@item 28 : Selected item cannot fit into memory
+This error is returned if a kernel, module, or raw file load command is
+either trying to load its data such that it won't fit into memory or it
+is simply too big.
+
+@item 29 : Disk write error
+This error is returned if there is a disk write error when trying to
+write to a particular disk. This would generally only occur during an
+install of set active partition command.
+
+@item 30 : Invalid argument
+This error is returned if an argument specified to a command is invalid.
+
+@item 31 : File is not sector aligned
+This error may occur only when you access a ReiserFS partition by
+block-lists (e.g. the command @command{install}). In this case, you
+should mount the partition with the @samp{-o notail} option.
+
+@item 32 : Must be authenticated
+This error is returned if you try to run a locked entry. You should
+enter a correct password before running such an entry.
+
+@item 33 : Serial device not configured
+This error is returned if you try to change your terminal to a serial
+one before initializing any serial device.
+
+@item 34 : No spare sectors on the disk
+This error is returned if a disk doesn't have enough spare space. This
+happens when you try to embed Stage 1.5 into the unused sectors after
+the MBR, but the first partition starts right after the MBR or they are
+used by EZ-BIOS.

+@node Invoking the grub shell
+@chapter Invoking the grub shell
+
+This chapter documents the grub shell @command{grub}. Note that the grub
+shell is an emulator; it doesn't run under the native environment, so it
+sometimes does something wrong. Therefore, you shouldn't trust it too
+much. If there is anything wrong with it, don't hesitate to try the
+native GRUB environment, especially when it guesses a wrong map between
+BIOS drives and OS devices.

+* Device map:: The map between BIOS drives and OS devices
+@end menu
+
+
+@node Basic usage
+@section Introduction into the grub shell
+
+You can use the command @command{grub} for installing GRUB under your
+operating systems and for a testbed when you add a new feature into GRUB
+or when fixing a bug. @command{grub} is almost the same as the Stage 2,
+and, in fact, it shares the source code with the Stage 2 and you can use
+the same commands (@pxref{Commands}) in @command{grub}. It is emulated by
+replacing BIOS calls with UNIX system calls and libc functions.
+
+The command @command{grub} accepts the following options:
+
+@table @option
+@item --help
+Print a summary of the command-line options and exit.
+
+@item --version
+Print the version number of GRUB and exit.
+
+@item --verbose
+Print some verbose messages for debugging purpose.
+
+@item --device-map=@var{file}
+Use the device map file @var{file}. The format is described in
+@ref{Device map}.
+
+@item --no-floppy
+Do not probe any floppy drive. This option has no effect if the option
+@option{--device-map} is specified (@pxref{Device map}).
+
+@item --probe-second-floppy
+Probe the second floppy drive. If this option is not specified, the grub
+shell does not probe it, as that sometimes takes a long time. If you
+specify the device map file (@pxref{Device map}), the grub shell just
+ignores this option.
+
+@item --config-file=@var{file}
+Read the configuration file @var{file} instead of
+@file{/boot/grub/menu.lst}. The format is the same as the normal GRUB
+syntax. See @ref{Filesystem}, for more information.
+
+@item --boot-drive=@var{drive}
+Set the stage2 @var{boot_drive} to @var{drive}. This argument should be
+an integer (decimal, octal or hexadecimal).
+
+@item --install-partition=@var{par}
+Set the stage2 @var{install_partition} to @var{par}. This argument
+should be an integer (decimal, octal or hexadecimal).
+
+@item --no-config-file
+Do not use the configuration file even if it can be read.
+
+@item --no-curses
+Do not use the screen handling interface by the curses even if it is
+available.
+
+@item --batch
+This option has the same meaning as @samp{--no-config-file --no-curses}.
+
+@item --read-only
+Disable writing to any disk.
+
+@item --hold
+Wait until a debugger will attach. This option is useful when you want
+to debug the startup code.
+@end table
+
+
+@node Installation under UNIX
+@section How to install GRUB via @command{grub}
+
+The installation procedure is the same as under the @dfn{native} Stage
+2. @xref{Installation}, for more information. The command
+@command{grub}-specific information is described here.
+
+What you should be careful about is @dfn{buffer cache}. @command{grub}
+makes use of raw devices instead of filesystems that your operating
+systems serve, so there exists a potential problem that some cache
+inconsistency may corrupt your filesystems. What we recommend is:
+
+@itemize @bullet
+@item
+If you can unmount drives to which GRUB may write any amount of data,
+unmount them before running @command{grub}.
+
+@item
+If a drive cannot be unmounted but can be mounted with the read-only
+flag, mount it in read-only mode. That should be secure.
+
+@item
+If a drive must be mounted with the read-write flag, make sure that no
+activity is being done on it while the command @command{grub} is
+running.
+
+@item
+Reboot your operating system as soon as possible. This is probably not
+required if you follow the rules above, but reboot is the most secure
+way.
+@end itemize
+
+In addition, enter the command @command{quit} when you finish the
+installation. That is @emph{very important} because @command{quit} makes
+the buffer cache consistent. Do not push @key{C-c}.
+
+If you want to install GRUB non-interactively, specify @samp{--batch}
+option in the command-line. This is a simple example:
+
+@example
+@group
+#!/bin/sh
+
+# Use /usr/sbin/grub if you are on an older system.
+/sbin/grub --batch <<EOT 1>/dev/null 2>/dev/null
+root (hd0,0)
+setup (hd0)
+quit
+EOT
+@end group
+@end example
+
+
+@node Device map
+@section The map between BIOS drives and OS devices
+
+When you specify the option @option{--device-map} (@pxref{Basic usage}),
+the grub shell creates the @dfn{device map file} automatically unless it
+already exists. The file name @file{/boot/grub/device.map} is preferred.
+
+If the device map file exists, the grub shell reads it to map BIOS
+drives to OS devices. This file consists of lines like this:
+
+@example
+@var{device} @var{file}
+@end example
+
+@var{device} is a drive specified in the GRUB syntax (@pxref{Device
+syntax}), and @var{file} is an OS file, which is normally a device
+file.
+
+The reason why the grub shell gives you the device map file is that it
+cannot guess the map between BIOS drives and OS devices correctly in
+some environments. For example, if you exchange the boot sequence
+between IDE and SCSI in your BIOS, it gets the order wrong.
+
+Thus, edit the file if the grub shell makes a mistake. You can put any
+comments in the file if needed, as the grub shell assumes that a line is
+just a comment if the first character is @samp{#}.
+
+
+@node Invoking grub-install
+@chapter Invoking grub-install
+
+The program @command{grub-install} installs GRUB on your drive using the
+grub shell (@pxref{Invoking the grub shell}). You must specify the
+device name on which you want to install GRUB, like this:
+
+@example
+grub-install @var{install_device}
+@end example
+
+The device name @var{install_device} is an OS device name or a GRUB
+device name.
+
+@command{grub-install} accepts the following options:
+
+@table @option
+@item --help
+Print a summary of the command-line options and exit.
+
+@item --version
+Print the version number of GRUB and exit.
+
+@item --force-lba
+Force GRUB to use LBA mode even for a buggy BIOS. Use this option only
+if your BIOS doesn't work properly in LBA mode even though it supports
+LBA mode.
+
+@item --root-directory=@var{dir}
+Install GRUB images under the directory @var{dir} instead of the root
+directory. This option is useful when you want to install GRUB into a
+separate partition or a removable disk. Here is an example in which
+you have a separate @dfn{boot} partition which is mounted on
+@file{/boot}:
+
+@example
+@kbd{grub-install --root-directory=/boot hd0}
+@end example
+
+@item --grub-shell=@var{file}
+Use @var{file} as the grub shell. You can append arbitrary options to
+@var{file} after the file name, like this:
+
+@example
+@kbd{grub-install --grub-shell="grub --read-only" /dev/fd0}
+@end example
+
+@item --recheck
+Recheck the device map, even if @file{/boot/grub/device.map} already
+exists. You should use this option whenever you add/remove a disk
+into/from your computer.
+@end table
+
+
+@node Invoking grub-md5-crypt
+@chapter Invoking grub-md5-crypt
+
+The program @command{grub-md5-crypt} encrypts a password in MD5 format.
+This is just a frontend of the grub shell (@pxref{Invoking the grub
+shell}). Passwords encrypted by this program can be used with the
+command @command{password} (@pxref{password}).
+
+@command{grub-md5-crypt} accepts the following options:
+
+@table @option
+@item --help
+Print a summary of the command-line options and exit.
+
+@item --version
+Print the version information and exit.
+
+@item --grub-shell=@var{file}
+Use @var{file} as the grub shell.
+@end table
+
+
+@node Invoking grub-terminfo
+@chapter Invoking grub-terminfo
+
+The program @command{grub-terminfo} generates a terminfo command from
+a terminfo name (@pxref{terminfo}). The result can be used in the
+configuration file, to define escape sequences. Because GRUB assumes
+that your terminal is vt100-compatible by default, this would be
+useful only if your terminal is uncommon (such as vt52).
+
+@command{grub-terminfo} accepts the following options:
+
+@table @option
+@item --help
+Print a summary of the command-line options and exit.
+
+@item --version
+Print the version information and exit.
+@end table
+
+You must specify one argument to this command. For example:
+
+@example
+@kbd{grub-terminfo vt52}
+@end example
+
+
+@node Invoking grub-set-default
+@chapter Invoking grub-set-default
+
+The program @command{grub-set-default} sets the default boot entry for
+GRUB. This automatically creates a file named @file{default} under
+your GRUB directory (i.e. @file{/boot/grub}), if it is not
+present. This file is used to determine the default boot entry when
+GRUB boots up your system when you use @samp{default saved} in your
+configuration file (@pxref{default}), and to save next default boot
+entry when you use @samp{savedefault} in a boot entry
+(@pxref{savedefault}).
+
+@command{grub-set-default} accepts the following options:
+
+@table @option
+@item --help
+Print a summary of the command-line options and exit.
+
+@item --version
+Print the version information and exit.
+
+@item --root-directory=@var{dir}
+Use the directory @var{dir} instead of the root directory
+(i.e. @file{/}) to define the location of the default file. This
+is useful when you mount a disk which is used for another system.
+@end table
+
+You must specify a single argument to @command{grub-set-default}. This
+argument is normally the number of a default boot entry. For example,
+if you have this configuration file:
+
+@example
+@group
+default saved
+timeout 10
+
+title GNU/Hurd
+root (hd0,0)
+...
+
+title GNU/Linux
+root (hd0,1)
+...
+@end group
+@end example
+
+and if you want to set the next default boot entry to GNU/Linux, you
+may execute this command:
+
+@example
+@kbd{grub-set-default 1}
+@end example
+
+Because the entry for GNU/Linux is @samp{1}. Note that entries are
+counted from zero. So, if you want to specify GNU/Hurd here, then you
+should specify @samp{0}.
+
+This feature is very useful if you want to test a new kernel or to
+make your system quite robust. @xref{Making your system robust}, for
+more hints about how to set up a robust system.
+
+
+@node Invoking mbchk
+@chapter Invoking mbchk
+
+The program @command{mbchk} checks for the format of a Multiboot
+kernel. We recommend using this program before booting your own kernel
+by GRUB.
+
+@command{mbchk} accepts the following options:
+
+@table @option
+@item --help
+Print a summary of the command-line options and exit.
+
+@item --version
+Print the version number of GRUB and exit.
+
+@item --quiet
+Suppress all normal output.
+@end table

+
+@node Obtaining and Building GRUB
+@appendix How to obtain and build GRUB
+
+@quotation
+@strong{Caution:} GRUB requires binutils-2.9.1.0.23 or later because the
+GNU assembler has been changed so that it can produce real 16bits
+machine code between 2.9.1 and 2.9.1.0.x. See
+@uref{http://sources.redhat.com/binutils/}, to obtain information on
+how to get the latest version.
+@end quotation
+
+GRUB is available from the GNU alpha archive site
+@uref{ftp://alpha.gnu.org/gnu/grub} or any of its mirrors. The file
+will be named grub-version.tar.gz. The current version is
+@value{VERSION}, so the file you should grab is:
+
+@uref{ftp://alpha.gnu.org/gnu/grub/grub-@value{VERSION}.tar.gz}
+
+To unbundle GRUB use the instruction:
+
+@example
+@kbd{zcat grub-@value{VERSION}.tar.gz | tar xvf -}
+@end example
+
+which will create a directory called @file{grub-@value{VERSION}} with
+all the sources. You can look at the file @file{INSTALL} for detailed
+instructions on how to build and install GRUB, but you should be able to
+just do:
+
+@example
+@group
+@kbd{cd grub-@value{VERSION}}
+@kbd{./configure}
+@kbd{make install}
+@end group
+@end example
+
+This will install the grub shell @file{grub} (@pxref{Invoking the grub
+shell}), the Multiboot checker @file{mbchk} (@pxref{Invoking mbchk}),
+and the GRUB images. This will also install the GRUB manual.
+
+Also, the latest version is available from the CVS. See
+@uref{http://savannah.gnu.org/cvs/?group=grub} for more information.

+
+@node Reporting bugs
+@appendix Reporting bugs
+
+These are the guideline for how to report bugs. Take a look at this
+list below before you submit bugs:
+
+@enumerate
+@item
+Before getting unsettled, read this manual through and through. Also,
+see the @uref{http://www.gnu.org/software/grub/grub-faq.html, GNU GRUB FAQ}.
+
+@item
+Always mention the information on your GRUB. The version number and the
+configuration are quite important. If you build it yourself, write the
+options specified to the configure script and your operating system,
+including the versions of gcc and binutils.
+
+@item
+If you have trouble with the installation, inform us of how you
+installed GRUB. Don't omit error messages, if any. Just @samp{GRUB hangs
+up when it boots} is not enough.
+
+The information on your hardware is also essential. These are especially
+important: the geometries and the partition tables of your hard disk
+drives and your BIOS.
+
+@item
+If GRUB cannot boot your operating system, write down
+@emph{everything} you see on the screen. Don't paraphrase them, like
+@samp{The foo OS crashes with GRUB, even though it can boot with the
+bar boot loader just fine}. Mention the commands you executed, the
+messages printed by them, and information on your operating system
+including the version number.
+
+@item
+Explain what you wanted to do. It is very useful to know your purpose
+and your wish, and how GRUB didn't satisfy you.
+
+@item
+If you can investigate the problem yourself, please do. That will give
+you and us much more information on the problem. Attaching a patch is
+even better.
+
+When you attach a patch, make the patch in unified diff format, and
+write ChangeLog entries. But, even when you make a patch, don't forget
+to explain the problem, so that we can understand what your patch is
+for.
+
+@item
+Write down anything that you think might be related. Please understand
+that we often need to reproduce the same problem you encounterred in our
+environment. So your information should be sufficient for us to do the
+same thing---Don't forget that we cannot see your computer directly. If
+you are not sure whether to state a fact or leave it out, state it!
+Reporting too many things is much better than omitting something
+important.
+@end enumerate
+
+If you follow the guideline above, submit a report to the
+@uref{http://savannah.gnu.org/bugs/?group=grub, Bug Tracking System}.
+Alternatively, you can submit a report via electronic mail to
+@email{bug-grub@@gnu.org}, but we strongly recommend that you use the
+Bug Tracking System, because e-mail can be passed over easily.
+
+Once we get your report, we will try to fix the bugs.

+
+@node Memory map
+@section The memory map of various components
+
+GRUB consists of two distinct components, called @dfn{stages}, which are
+loaded at different times in the boot process. Because they run
+mutual-exclusively, sometimes a memory area overlaps with another
+memory area. And, even in one stage, a single memory area can be used
+for various purposes, because their usages are mutually exclusive.
+
+Here is the memory map of the various components:
+
+@table @asis
+@item 0 to 4K-1
+BIOS and real mode interrupts
+
+@item 0x07BE to 0x07FF
+Partition table passed to another boot loader
+
+@item down from 8K-1
+Real mode stack
+
+@item 0x2000 to ?
+The optional Stage 1.5 is loaded here
+
+@item 0x2000 to 0x7FFF
+Command-line buffer for Multiboot kernels and modules
+
+@item 0x7C00 to 0x7DFF
+Stage 1 is loaded here by BIOS or another boot loader
+
+@item 0x7F00 to 0x7F42
+LBA drive parameters
+
+@item 0x8000 to ?
+Stage2 is loaded here
+
+@item The end of Stage 2 to 416K-1
+Heap, in particular used for the menu
+
+@item down from 416K-1
+Protected mode stack
+
+@item 416K to 448K-1
+Filesystem buffer
+
+@item 448K to 479.5K-1
+Raw device buffer
+
+@item 479.5K to 480K-1
+512-byte scratch area
+
+@item 480K to 512K-1
+Buffers for various functions, such as password, command-line, cut and
+paste, and completion.
+
+@item The last 1K of lower memory
+Disk swapping code and data
+@end table
+
+See the file @file{stage2/shared.h}, for more information.
+
+
+@node Embedded data
+@section Embedded variables in GRUB
+
+Stage 1 and Stage 2 have embedded variables whose locations are
+well-defined, so that the installation can patch the binary file
+directly without recompilation of the stages.
+
+In Stage 1, these are defined:
+
+@table @code
+@item 0x3E
+The version number (not GRUB's, but the installation mechanism's).
+
+@item 0x40
+The boot drive. If it is 0xFF, use a drive passed by BIOS.
+
+@item 0x41
+The flag for if forcing LBA.
+
+@item 0x42
+The starting address of Stage 2.
+
+@item 0x44
+The first sector of Stage 2.
+
+@item 0x48
+The starting segment of Stage 2.
+
+@item 0x1FE
+The signature (@code{0xAA55}).
+@end table
+
+See the file @file{stage1/stage1.S}, for more information.
+
+In the first sector of Stage 1.5 and Stage 2, the block lists are
+recorded between @code{firstlist} and @code{lastlist}. The address of
+@code{lastlist} is determined when assembling the file
+@file{stage2/start.S}.
+
+The trick here is that it is actually read backward, and the first
+8-byte block list is not read here, but after the pointer is decremented
+8 bytes, then after reading it, it decrements again, reads, and so on,
+until it is finished. The terminating condition is when the number of
+sectors to be read in the next block list is zero.
+
+The format of a block list can be seen from the example in the code just
+before the @code{firstlist} label. Note that it is always from the
+beginning of the disk, but @emph{not} relative to the partition
+boundaries.
+
+In the second sector of Stage 1.5 and Stage 2, these are defined:
+
+@table @asis
+@item @code{0x6}
+The version number (likewise, the installation mechanism's).
+
+@item @code{0x8}
+The installed partition.
+
+@item @code{0xC}
+The saved entry number.
+
+@item @code{0x10}
+The identifier.
+
+@item @code{0x11}
+The flag for if forcing LBA.
+
+@item @code{0x12}
+The version string (GRUB's).
+
+@item @code{0x12} + @dfn{the length of the version string}
+The name of a configuration file.
+@end table
+
+See the file @file{stage2/asm.S}, for more information.
+
+
+@node Filesystem interface
+@section The generic interface for filesystems
+
+For any particular partition, it is presumed that only one of the
+@dfn{normal} filesystems such as FAT, FFS, or ext2fs can be used, so
+there is a switch table managed by the functions in
+@file{disk_io.c}. The notation is that you can only @dfn{mount} one at a
+time.
+
+The block list filesystem has a special place in the system. In addition
+to the @dfn{normal} filesystem (or even without one mounted), you can
+access disk blocks directly (in the indicated partition) via the block
+list notation. Using the block list filesystem doesn't effect any other
+filesystem mounts.
+
+The variables which can be read by the filesystem backend are:
+
+@vtable @code
+@item current_drive
+The current BIOS drive number (numbered from 0, if a floppy, and
+numbered from 0x80, if a hard disk).
+
+@item current_partition
+The current partition number.
+
+@item current_slice
+The current partition type.
+
+@item saved_drive
+The @dfn{drive} part of the root device.
+
+@item saved_partition
+The @dfn{partition} part of the root device.
+
+@item part_start
+The current partition starting address, in sectors.
+
+@item part_length
+The current partition length, in sectors.
+
+@item print_possibilities
+True when the @code{dir} function should print the possible completions
+of a file, and false when it should try to actually open a file of that
+name.
+
+@item FSYS_BUF
+Filesystem buffer which is 32K in size, to use in any way which the
+filesystem backend desires.
+@end vtable
+
+The variables which need to be written by a filesystem backend are:
+
+@vtable @code
+@item filepos
+The current position in the file, in sectors.
+
+@strong{Caution:} the value of @var{filepos} can be changed out from
+under the filesystem code in the current implementation. Don't depend on
+it being the same for later calls into the backend code!
+
+@item filemax
+The length of the file.
+
+@item disk_read_func
+The value of @var{disk_read_hook} @emph{only} during reading of data
+for the file, not any other fs data, inodes, FAT tables, whatever, then
+set to @code{NULL} at all other times (it will be @code{NULL} by
+default). If this isn't done correctly, then the @command{testload} and
+@command{install} commands won't work correctly.
+@end vtable
+
+The functions expected to be used by the filesystem backend are:
+
+@ftable @code
+@item devread
+Only read sectors from within a partition. Sector 0 is the first sector
+in the partition.
+
+@item grub_read
+If the backend uses the block list code, then @code{grub_read} can be
+used, after setting @var{block_file} to 1.
+
+@item print_a_completion
+If @var{print_possibilities} is true, call @code{print_a_completion} for
+each possible file name. Otherwise, the file name completion won't work.
+@end ftable
+
+The functions expected to be defined by the filesystem backend are
+described at least moderately in the file @file{filesys.h}. Their usage
+is fairly evident from their use in the functions in @file{disk_io.c},
+look for the use of the @var{fsys_table} array.
+
+@strong{Caution:} The semantics are such that then @samp{mount}ing the
+filesystem, presume the filesystem buffer @code{FSYS_BUF} is corrupted,
+and (re-)load all important contents. When opening and reading a file,
+presume that the data from the @samp{mount} is available, and doesn't
+get corrupted by the open/read (i.e. multiple opens and/or reads will be
+done with only one mount if in the same filesystem).
+
+
+@node Command interface
+@section The generic interface for built-ins
+
+GRUB built-in commands are defined in a uniformal interface, whether
+they are menu-specific or can be used anywhere. The definition of a
+builtin command consists of two parts: the code itself and the table of
+the information.
+
+The code must be a function which takes two arguments, a command-line
+string and flags, and returns an @samp{int} value. The @dfn{flags}
+argument specifies how the function is called, using a bit mask. The
+return value must be zero if successful, otherwise non-zero. So it is
+normally enough to return @var{errnum}.
+
+The table of the information is represented by the structure
+@code{struct builtin}, which contains the name of the command, a pointer
+to the function, flags, a short description of the command and a long
+description of the command. Since the descriptions are used only for
+help messages interactively, you don't have to define them, if the
+command may not be called interactively (such as @command{title}).
+
+The table is finally registered in the table @var{builtin_table}, so
+that @code{run_script} and @code{enter_cmdline} can find the
+command. See the files @file{cmdline.c} and @file{builtins.c}, for more
+details.
+
+
+@node Bootstrap tricks
+@section The bootstrap mechanism used in GRUB
+
+The disk space can be used in a boot loader is very restricted because
+a MBR (@pxref{MBR}) is only 512 bytes but it also contains a partition
+table (@pxref{Partition table}) and a BPB. So the question is how to
+make a boot loader code enough small to be fit in a MBR.
+
+However, GRUB is a very large program, so we break GRUB into 2 (or 3)
+distinct components, @dfn{Stage 1} and @dfn{Stage 2} (and optionally
+@dfn{Stage 1.5}). @xref{Memory map}, for more information.
+
+We embed Stage 1 in a MBR or in the boot sector of a partition, and
+place Stage 2 in a filesystem. The optional Stage 1.5 can be installed
+in a filesystem, in the @dfn{boot loader} area in a FFS or a ReiserFS,
+and in the sectors right after a MBR, because Stage 1.5 is enough small
+and the sectors right after a MBR is normally an unused region. The size
+of this region is the number of sectors per head minus 1.
+
+Thus, all Stage1 must do is just load Stage2 or Stage1.5. But even if
+Stage 1 needs not to support the user interface or the filesystem
+interface, it is impossible to make Stage 1 less than 400 bytes, because
+GRUB should support both the CHS mode and the LBA mode (@pxref{Low-level
+disk I/O}).
+
+The solution used by GRUB is that Stage 1 loads only the first sector of
+Stage 2 (or Stage 1.5) and Stage 2 itself loads the rest. The flow of
+Stage 1 is:
+
+@enumerate
+@item
+Initialize the system briefly.
+
+@item
+Detect the geometry and the accessing mode of the @dfn{loading drive}.
+
+@item
+Load the first sector of Stage 2.
+
+@item
+Jump to the starting address of the Stage 2.
+@end enumerate
+
+The flow of Stage 2 (and Stage 1.5) is:
+
+@enumerate
+@item
+Load the rest of itself to the real starting address, that is, the
+starting address plus 512 bytes. The block lists are stored in the last
+part of the first sector.
+
+@item
+Long jump to the real starting address.
+@end enumerate
+
+Note that Stage 2 (or Stage 1.5) does not probe the geometry
+or the accessing mode of the @dfn{loading drive}, since Stage 1 has
+already probed them.

+thing to make one big patch which changes many things. Instead,
+segregate features and produce many patches.
+
+@item
+Use as late code as possible, for the original code. The CVS repository
+always has the current version (@pxref{Obtaining and Building GRUB}).
+
+@item
+Write ChangeLog entries. @xref{Change Logs, , Change Logs, standards,
+GNU Coding Standards}, if you don't know how to write ChangeLog.
+
+@item
+Make patches in unified diff format. @samp{diff -urN} is appropriate in
+most cases.
+
+@item
+Don't make patches reversely. Reverse patches are difficult to read and
+use.
+
+@item
+Be careful enough of the license term and the copyright. Because GRUB
+is under GNU General Public License, you may not steal code from
+software whose license is incompatible against GPL. And, if you copy
+code written by others, you must not ignore their copyrights. Feel free
+to ask GRUB maintainers, whenever you are not sure what you should do.
+
+@item
+If your patch is too large to send in e-mail, put it at somewhere we can
+see. Usually, you shouldn't send e-mail over 20K.

+
+@node Motivation
+@section The background of Multiboot Specification
+
+Every operating system ever created tends to have its own boot loader.
+Installing a new operating system on a machine generally involves
+installing a whole new set of boot mechanisms, each with completely
+different install-time and boot-time user interfaces. Getting multiple
+operating systems to coexist reliably on one machine through typical
+@dfn{chaining} mechanisms can be a nightmare. There is little or no
+choice of boot loaders for a particular operating system --- if the one
+that comes with the operating system doesn't do exactly what you want,
+or doesn't work on your machine, you're screwed.
+
+While we may not be able to fix this problem in existing commercial
+operating systems, it shouldn't be too difficult for a few people in the
+free operating system communities to put their heads together and solve
+this problem for the popular free operating systems. That's what this
+specification aims for. Basically, it specifies an interface between a
+boot loader and a operating system, such that any complying boot loader
+should be able to load any complying operating system. This
+specification does @emph{not} specify how boot loaders should work ---
+only how they must interface with the operating system being loaded.
+
+
+@node Architecture
+@section The target architecture
+
+This specification is primarily targeted at @sc{pc}, since they are the
+most common and have the largest variety of operating systems and boot
+loaders. However, to the extent that certain other architectures may
+need a boot specification and do not have one already, a variation of
+this specification, stripped of the x86-specific details, could be
+adopted for them as well.
+
+
+@node Operating systems
+@section The target operating systems
+
+This specification is targeted toward free 32-bit operating systems
+that can be fairly easily modified to support the specification without
+going through lots of bureaucratic rigmarole. The particular free
+operating systems that this specification is being primarily designed
+for are Linux, FreeBSD, NetBSD, Mach, and VSTa. It is hoped that other
+emerging free operating systems will adopt it from the start, and thus
+immediately be able to take advantage of existing boot loaders. It would
+be nice if commercial operating system vendors eventually adopted this
+specification as well, but that's probably a pipe dream.
+
+
+@node Boot sources
+@section Boot sources
+
+It should be possible to write compliant boot loaders that load the OS
+image from a variety of sources, including floppy disk, hard disk, and
+across a network.
+
+Disk-based boot loaders may use a variety of techniques to find the
+relevant OS image and boot module data on disk, such as by
+interpretation of specific file systems (e.g. the BSD/Mach boot loader),
+using precalculated @dfn{block lists} (e.g. LILO), loading from a
+special @dfn{boot partition} (e.g. OS/2), or even loading from within
+another operating system (e.g. the VSTa boot code, which loads from
+DOS). Similarly, network-based boot loaders could use a variety of
+network hardware and protocols.
+
+It is hoped that boot loaders will be created that support multiple
+loading mechanisms, increasing their portability, robustness, and
+user-friendliness.
+
+
+@node Boot-time configuration
+@section Configure an operating system at boot-time
+
+It is often necessary for one reason or another for the user to be able
+to provide some configuration information to an operating system
+dynamically at boot time. While this specification should not dictate
+how this configuration information is obtained by the boot loader, it
+should provide a standard means for the boot loader to pass such
+information to the operating system.
+
+
+@node Convenience to operating systems
+@section How to make OS development easier
+
+OS images should be easy to generate. Ideally, an OS image should simply
+be an ordinary 32-bit executable file in whatever file format the
+operating system normally uses. It should be possible to @code{nm} or
+disassemble OS images just like normal executables. Specialized tools
+should not be required to create OS images in a @emph{special} file
+format. If this means shifting some work from the operating system to
+a boot loader, that is probably appropriate, because all the memory
+consumed by the boot loader will typically be made available again after
+the boot process is created, whereas every bit of code in the OS image
+typically has to remain in memory forever. The operating system should
+not have to worry about getting into 32-bit mode initially, because mode
+switching code generally needs to be in the boot loader anyway in order
+to load operating system data above the 1MB boundary, and forcing the
+operating system to do this makes creation of OS images much more
+difficult.
+
+Unfortunately, there is a horrendous variety of executable file formats
+even among free Unix-like @sc{pc}-based operating systems --- generally
+a different format for each operating system. Most of the relevant free
+operating systems use some variant of a.out format, but some are moving
+to @sc{elf}. It is highly desirable for boot loaders not to have to be
+able to interpret all the different types of executable file formats in
+existence in order to load the OS image --- otherwise the boot loader
+effectively becomes operating system specific again.
+
+This specification adopts a compromise solution to this
+problem. Multiboot-compliant OS images always contain a magic
+@dfn{Multiboot header} (@pxref{OS image format}), which allows the boot
+loader to load the image without having to understand numerous a.out
+variants or other executable formats. This magic header does not need to
+be at the very beginning of the executable file, so kernel images can
+still conform to the local a.out format variant in addition to being
+Multiboot-compliant.
+
+
+@node Boot modules
+@section Boot modules
+
+Many modern operating system kernels, such as those of VSTa and Mach, do
+not by themselves contain enough mechanism to get the system fully
+operational: they require the presence of additional software modules at
+boot time in order to access devices, mount file systems, etc. While
+these additional modules could be embedded in the main OS image along
+with the kernel itself, and the resulting image be split apart manually
+by the operating system when it receives control, it is often more
+flexible, more space-efficient, and more convenient to the operating
+system and user if the boot loader can load these additional modules
+independently in the first place.
+
+Thus, this specification should provide a standard method for a boot
+loader to indicate to the operating system what auxiliary boot modules
+were loaded, and where they can be found. Boot loaders don't have to
+support multiple boot modules, but they are strongly encouraged to,
+because some operating systems will be unable to boot without them.
+
+
+@node Terminology
+@chapter The definitions of terms used through the specification
+
+@table @dfn
+@item must
+We use the term @dfn{must}, when any boot loader or OS image needs to
+follow a rule --- otherwise, the boot loader or OS image is @emph{not}
+Multiboot-compliant.
+
+@item should
+We use the term @dfn{should}, when any boot loader or OS image is
+recommended to follow a rule, but it doesn't need to follow the rule.
+
+@item may
+We use the term @dfn{may}, when any boot loader or OS image is allowed
+to follow a rule.
+
+@item boot loader
+Whatever program or set of programs loads the image of the final
+operating system to be run on the machine. The boot loader may itself
+consist of several stages, but that is an implementation detail not
+relevant to this specification. Only the @emph{final} stage of the boot
+loader --- the stage that eventually transfers control to an operating
+system --- must follow the rules specified in this document in order
+to be @dfn{Multiboot-compliant}; earlier boot loader stages may be
+designed in whatever way is most convenient.
+
+@item OS image
+The initial binary image that a boot loader loads into memory and
+transfers control to start an operating system. The OS image is
+typically an executable containing the operating system kernel.
+
+@item boot module
+Other auxiliary files that a boot loader loads into memory along with
+an OS image, but does not interpret in any way other than passing their
+locations to the operating system when it is invoked.
+
+@item Multiboot-compliant
+A boot loader or an OS image which follows the rules defined as
+@dfn{must} is Multiboot-compliant. When this specification specifies a
+rule as @dfn{should} or @dfn{may}, a Multiboot-complaint boot loader/OS
+image doesn't need to follow the rule.
+
+@item u8
+The type of unsigned 8-bit data.
+
+@item u16
+The type of unsigned 16-bit data. Because the target architecture is
+little-endian, u16 is coded in little-endian.
+
+@item u32
+The type of unsigned 32-bit data. Because the target architecture is
+little-endian, u32 is coded in little-endian.
+
+@item u64
+The type of unsigned 64-bit data. Because the target architecture is
+little-endian, u64 is coded in little-endian.
+@end table
+
+
+@node Specification
+@chapter The exact definitions of Multiboot Specification
+
+There are three main aspects of a boot loader/OS image interface:
+
+@enumerate
+@item
+The format of an OS image as seen by a boot loader.
+
+@item
+The state of a machine when a boot loader starts an operating
+system.
+
+@item
+The format of information passed by a boot loader to an operating
+system.
+@end enumerate
+
+@menu
+* OS image format::
+* Machine state::
+* Boot information format::
+@end menu
+
+
+@node OS image format
+@section OS image format
+
+An OS image may be an ordinary 32-bit executable file in the standard
+format for that particular operating system, except that it may be
+linked at a non-default load address to avoid loading on top of the
+@sc{pc}'s I/O region or other reserved areas, and of course it should
+not use shared libraries or other fancy features.
+
+An OS image must contain an additional header called @dfn{Multiboot
+header}, besides the headers of the format used by the OS image. The
+Multiboot header must be contained completely within the first 8192
+bytes of the OS image, and must be longword (32-bit) aligned. In
+general, it should come @emph{as early as possible}, and may be
+embedded in the beginning of the text segment after the @emph{real}
+executable header.

+
+
+@node Header magic fields
+@subsection The magic fields of Multiboot header
+
+@table @samp
+@item magic
+The field @samp{magic} is the magic number identifying the header,
+which must be the hexadecimal value @code{0x1BADB002}.
+
+@item flags
+The field @samp{flags} specifies features that the OS image requests or
+requires of an boot loader. Bits 0-15 indicate requirements; if the
+boot loader sees any of these bits set but doesn't understand the flag
+or can't fulfill the requirements it indicates for some reason, it must
+notify the user and fail to load the OS image. Bits 16-31 indicate
+optional features; if any bits in this range are set but the boot loader
+doesn't understand them, it may simply ignore them and proceed as
+usual. Naturally, all as-yet-undefined bits in the @samp{flags} word
+must be set to zero in OS images. This way, the @samp{flags} fields
+serves for version control as well as simple feature selection.
+
+If bit 0 in the @samp{flags} word is set, then all boot modules loaded
+along with the operating system must be aligned on page (4KB)
+boundaries. Some operating systems expect to be able to map the pages
+containing boot modules directly into a paged address space during
+startup, and thus need the boot modules to be page-aligned.
+
+If bit 1 in the @samp{flags} word is set, then information on available
+memory via at least the @samp{mem_*} fields of the Multiboot information
+structure (@pxref{Boot information format}) must be included. If the
+boot loader is capable of passing a memory map (the @samp{mmap_*} fields)
+and one exists, then it may be included as well.
+
+If bit 2 in the @samp{flags} word is set, information about the video
+mode table (@pxref{Boot information format}) must be available to the
+kernel.
+
+If bit 16 in the @samp{flags} word is set, then the fields at offsets
+8-24 in the Multiboot header are valid, and the boot loader should use
+them instead of the fields in the actual executable header to calculate
+where to load the OS image. This information does not need to be
+provided if the kernel image is in @sc{elf} format, but it @emph{must}
+be provided if the images is in a.out format or in some other
+format. Compliant boot loaders must be able to load images that either
+are in @sc{elf} format or contain the load address information embedded
+in the Multiboot header; they may also directly support other executable
+formats, such as particular a.out variants, but are not required to.
+
+@item checksum
+The field @samp{checksum} is a 32-bit unsigned value which, when added
+to the other magic fields (i.e. @samp{magic} and @samp{flags}), must
+have a 32-bit unsigned sum of zero.
+@end table
+
+
+@node Header address fields
+@subsection The address fields of Multiboot header
+
+All of the address fields enabled by flag bit 16 are physical addresses.
+The meaning of each is as follows:
+
+@table @code
+@item header_addr
+Contains the address corresponding to the beginning of the Multiboot
+header --- the physical memory location at which the magic value is
+supposed to be loaded. This field serves to @dfn{synchronize} the
+mapping between OS image offsets and physical memory addresses.
+
+@item load_addr
+Contains the physical address of the beginning of the text segment. The
+offset in the OS image file at which to start loading is defined by the
+offset at which the header was found, minus (header_addr -
+load_addr). load_addr must be less than or equal to header_addr.
+
+@item load_end_addr
+Contains the physical address of the end of the data
+segment. (load_end_addr - load_addr) specifies how much data to load.
+This implies that the text and data segments must be consecutive in the
+OS image; this is true for existing a.out executable formats.
+If this field is zero, the boot loader assumes that the text and data
+segments occupy the whole OS image file.
+
+@item bss_end_addr
+Contains the physical address of the end of the bss segment. The boot
+loader initializes this area to zero, and reserves the memory it
+occupies to avoid placing boot modules and other data relevant to the
+operating system in that area. If this field is zero, the boot loader
+assumes that no bss segment is present.
+
+@item entry_addr
+The physical address to which the boot loader should jump in order to
+start running the operating system.
+@end table
+
+
+@node Header graphics fields
+@subsection The graphics fields of Multiboot header
+
+All of the graphics fields are enabled by flag bit 2. They specify the
+preferred graphics mode. Note that that is only a @emph{recommended}
+mode by the OS image. If the mode exists, the boot loader should set
+it, when the user doesn't specify a mode explicitly. Otherwise, the
+boot loader should fall back to a similar mode, if available.
+
+The meaning of each is as follows:
+
+@table @code
+@item mode_type
+Contains @samp{0} for linear graphics mode or @samp{1} for
+EGA-standard text mode. Everything else is reserved for future
+expansion. Note that the boot loader may set a text mode, even if this
+field contains @samp{0}.
+
+@item width
+Contains the number of the columns. This is specified in pixels in a
+graphics mode, and in characters in a text mode. The value zero
+indicates that the OS image has no preference.
+
+@item height
+Contains the number of the lines. This is specified in pixels in a
+graphics mode, and in characters in a text mode. The value zero
+indicates that the OS image has no preference.
+
+@item depth
+Contains the number of bits per pixel in a graphics mode, and zero in
+a text mode. The value zero indicates that the OS image has no
+preference.
+@end table
+
+
+@node Machine state
+@section Machine state
+
+When the boot loader invokes the 32-bit operating system, the machine
+must have the following state:
+
+@table @samp
+@item EAX
+Must contain the magic value @samp{0x2BADB002}; the presence of this
+value indicates to the operating system that it was loaded by a
+Multiboot-compliant boot loader (e.g. as opposed to another type of
+boot loader that the operating system can also be loaded from).
+
+@item EBX
+Must contain the 32-bit physical address of the Multiboot
+information structure provided by the boot loader (@pxref{Boot
+information format}).
+
+@item CS
+Must be a 32-bit read/execute code segment with an offset of @samp{0}
+and a limit of @samp{0xFFFFFFFF}. The exact value is undefined.
+
+@item DS
+@itemx ES
+@itemx FS
+@itemx GS
+@itemx SS
+Must be a 32-bit read/write data segment with an offset of @samp{0}
+and a limit of @samp{0xFFFFFFFF}. The exact values are all undefined.
+
+@item A20 gate
+Must be enabled.
+
+@item CR0
+Bit 31 (PG) must be cleared. Bit 0 (PE) must be set. Other bits are
+all undefined.
+
+@item EFLAGS
+Bit 17 (VM) must be cleared. Bit 9 (IF) must be cleared. Other bits
+are all undefined.
+@end table
+
+All other processor registers and flag bits are undefined. This
+includes, in particular:
+
+@table @samp
+@item ESP
+The OS image must create its own stack as soon as it needs one.
+
+@item GDTR
+Even though the segment registers are set up as described above, the
+@samp{GDTR} may be invalid, so the OS image must not load any segment
+registers (even just reloading the same values!) until it sets up its
+own @samp{GDT}.
+
+@item IDTR
+The OS image must leave interrupts disabled until it sets up its own
+@code{IDT}.
+@end table
+
+However, other machine state should be left by the boot loader in
+@dfn{normal working order}, i.e. as initialized by the @sc{bios} (or
+DOS, if that's what the boot loader runs from). In other words, the
+operating system should be able to make @sc{bios} calls and such after
+being loaded, as long as it does not overwrite the @sc{bios} data
+structures before doing so. Also, the boot loader must leave the
+@sc{pic} programmed with the normal @sc{bios}/DOS values, even if it
+changed them during the switch to 32-bit mode.
+
+
+@node Boot information format
+@section Boot information format
+
+FIXME: Split this chapter like the chapter ``OS image format''.
+
+Upon entry to the operating system, the @code{EBX} register contains the
+physical address of a @dfn{Multiboot information} data structure,
+through which the boot loader communicates vital information to the
+operating system. The operating system can use or ignore any parts of
+the structure as it chooses; all information passed by the boot loader
+is advisory only.
+
+The Multiboot information structure and its related substructures may be
+placed anywhere in memory by the boot loader (with the exception of the
+memory reserved for the kernel and boot modules, of course). It is the
+operating system's responsibility to avoid overwriting this memory until
+it is done using it.
+
+The format of the Multiboot information structure (as defined so far)
+follows:
+
+@example
+@group
+ +-------------------+
+0 | flags | (required)
+ +-------------------+
+4 | mem_lower | (present if flags[0] is set)
+8 | mem_upper | (present if flags[0] is set)
+ +-------------------+
+12 | boot_device | (present if flags[1] is set)
+ +-------------------+
+16 | cmdline | (present if flags[2] is set)
+ +-------------------+
+20 | mods_count | (present if flags[3] is set)
+24 | mods_addr | (present if flags[3] is set)
+ +-------------------+
+28 - 40 | syms | (present if flags[4] or
+ | | flags[5] is set)
+ +-------------------+
+44 | mmap_length | (present if flags[6] is set)
+48 | mmap_addr | (present if flags[6] is set)
+ +-------------------+
+52 | drives_length | (present if flags[7] is set)
+56 | drives_addr | (present if flags[7] is set)
+ +-------------------+
+60 | config_table | (present if flags[8] is set)
+ +-------------------+
+64 | boot_loader_name | (present if flags[9] is set)
+ +-------------------+
+68 | apm_table | (present if flags[10] is set)
+ +-------------------+
+72 | vbe_control_info | (present if flags[11] is set)
+76 | vbe_mode_info |
+80 | vbe_mode |
+82 | vbe_interface_seg |
+84 | vbe_interface_off |
+86 | vbe_interface_len |
+ +-------------------+
+@end group
+@end example
+
+The first longword indicates the presence and validity of other fields
+in the Multiboot information structure. All as-yet-undefined bits must
+be set to zero by the boot loader. Any set bits that the operating
+system does not understand should be ignored. Thus, the @samp{flags}
+field also functions as a version indicator, allowing the Multiboot
+information structure to be expanded in the future without breaking
+anything.
+
+If bit 0 in the @samp{flags} word is set, then the @samp{mem_*} fields
+are valid. @samp{mem_lower} and @samp{mem_upper} indicate the amount of
+lower and upper memory, respectively, in kilobytes. Lower memory starts
+at address 0, and upper memory starts at address 1 megabyte. The maximum
+possible value for lower memory is 640 kilobytes. The value returned for
+upper memory is maximally the address of the first upper memory hole
+minus 1 megabyte. It is not guaranteed to be this value.
+
+If bit 1 in the @samp{flags} word is set, then the @samp{boot_device}
+field is valid, and indicates which @sc{bios} disk device the boot
+loader loaded the OS image from. If the OS image was not loaded from a
+@sc{bios} disk, then this field must not be present (bit 3 must be
+clear). The operating system may use this field as a hint for
+determining its own @dfn{root} device, but is not required to. The
+@samp{boot_device} field is laid out in four one-byte subfields as
+follows:
+
+@example
+@group
++-------+-------+-------+-------+
+| drive | part1 | part2 | part3 |
++-------+-------+-------+-------+
+@end group
+@end example
+
+The first byte contains the @sc{bios} drive number as understood by the
+@sc{bios} INT 0x13 low-level disk interface: e.g. 0x00 for the first
+floppy disk or 0x80 for the first hard disk.
+
+The three remaining bytes specify the boot partition. @samp{part1}
+specifies the @dfn{top-level} partition number, @samp{part2} specifies a
+@dfn{sub-partition} in the top-level partition, etc. Partition numbers
+always start from zero. Unused partition bytes must be set to 0xFF. For
+example, if the disk is partitioned using a simple one-level DOS
+partitioning scheme, then @samp{part1} contains the DOS partition
+number, and @samp{part2} and @samp{part3} are both 0xFF. As another
+example, if a disk is partitioned first into DOS partitions, and then
+one of those DOS partitions is subdivided into several BSD partitions
+using BSD's @dfn{disklabel} strategy, then @samp{part1} contains the DOS
+partition number, @samp{part2} contains the BSD sub-partition within
+that DOS partition, and @samp{part3} is 0xFF.
+
+DOS extended partitions are indicated as partition numbers starting from
+4 and increasing, rather than as nested sub-partitions, even though the
+underlying disk layout of extended partitions is hierarchical in
+nature. For example, if the boot loader boots from the second extended
+partition on a disk partitioned in conventional DOS style, then
+@samp{part1} will be 5, and @samp{part2} and @samp{part3} will both be
+0xFF.
+
+If bit 2 of the @samp{flags} longword is set, the @samp{cmdline} field
+is valid, and contains the physical address of the command line to
+be passed to the kernel. The command line is a normal C-style
+zero-terminated string.
+
+If bit 3 of the @samp{flags} is set, then the @samp{mods} fields
+indicate to the kernel what boot modules were loaded along with the
+kernel image, and where they can be found. @samp{mods_count} contains
+the number of modules loaded; @samp{mods_addr} contains the physical
+address of the first module structure. @samp{mods_count} may be zero,
+indicating no boot modules were loaded, even if bit 1 of @samp{flags} is
+set. Each module structure is formatted as follows:
+
+@example
+@group
+ +-------------------+
+0 | mod_start |
+4 | mod_end |
+ +-------------------+
+8 | string |
+ +-------------------+
+12 | reserved (0) |
+ +-------------------+
+@end group
+@end example
+
+The first two fields contain the start and end addresses of the boot
+module itself. The @samp{string} field provides an arbitrary string to
+be associated with that particular boot module; it is a zero-terminated
+ASCII string, just like the kernel command line. The @samp{string} field
+may be 0 if there is no string associated with the module. Typically the
+string might be a command line (e.g. if the operating system treats boot
+modules as executable programs), or a pathname (e.g. if the operating
+system treats boot modules as files in a file system), but its exact use
+is specific to the operating system. The @samp{reserved} field must be
+set to 0 by the boot loader and ignored by the operating system.
+
+@strong{Caution:} Bits 4 & 5 are mutually exclusive.
+
+If bit 4 in the @samp{flags} word is set, then the following fields in
+the Multiboot information structure starting at byte 28 are valid:
+
+@example
+@group
+ +-------------------+
+28 | tabsize |
+32 | strsize |
+36 | addr |
+40 | reserved (0) |
+ +-------------------+
+@end group
+@end example
+
+These indicate where the symbol table from an a.out kernel image can be
+found. @samp{addr} is the physical address of the size (4-byte unsigned
+long) of an array of a.out format @dfn{nlist} structures, followed
+immediately by the array itself, then the size (4-byte unsigned long) of
+a set of zero-terminated @sc{ascii} strings (plus sizeof(unsigned long) in
+this case), and finally the set of strings itself. @samp{tabsize} is
+equal to its size parameter (found at the beginning of the symbol
+section), and @samp{strsize} is equal to its size parameter (found at
+the beginning of the string section) of the following string table to
+which the symbol table refers. Note that @samp{tabsize} may be 0,
+indicating no symbols, even if bit 4 in the @samp{flags} word is set.
+
+If bit 5 in the @samp{flags} word is set, then the following fields in
+the Multiboot information structure starting at byte 28 are valid:
+
+@example
+@group
+ +-------------------+
+28 | num |
+32 | size |
+36 | addr |
+40 | shndx |
+ +-------------------+
+@end group
+@end example
+
+These indicate where the section header table from an ELF kernel is, the
+size of each entry, number of entries, and the string table used as the
+index of names. They correspond to the @samp{shdr_*} entries
+(@samp{shdr_num}, etc.) in the Executable and Linkable Format (@sc{elf})
+specification in the program header. All sections are loaded, and the
+physical address fields of the @sc{elf} section header then refer to where
+the sections are in memory (refer to the i386 @sc{elf} documentation for
+details as to how to read the section header(s)). Note that
+@samp{shdr_num} may be 0, indicating no symbols, even if bit 5 in the
+@samp{flags} word is set.
+
+If bit 6 in the @samp{flags} word is set, then the @samp{mmap_*} fields
+are valid, and indicate the address and length of a buffer containing a
+memory map of the machine provided by the @sc{bios}. @samp{mmap_addr} is
+the address, and @samp{mmap_length} is the total size of the buffer. The
+buffer consists of one or more of the following size/structure pairs
+(@samp{size} is really used for skipping to the next pair):
+
+@example
+@group
+ +-------------------+
+-4 | size |
+ +-------------------+
+0 | base_addr_low |
+4 | base_addr_high |
+8 | length_low |
+12 | length_high |
+16 | type |
+ +-------------------+
+@end group
+@end example
+
+where @samp{size} is the size of the associated structure in bytes, which
+can be greater than the minimum of 20 bytes. @samp{base_addr_low} is the
+lower 32 bits of the starting address, and @samp{base_addr_high} is the
+upper 32 bits, for a total of a 64-bit starting address. @samp{length_low}
+is the lower 32 bits of the size of the memory region in bytes, and
+@samp{length_high} is the upper 32 bits, for a total of a 64-bit
+length. @samp{type} is the variety of address range represented, where a
+value of 1 indicates available @sc{ram}, and all other values currently
+indicated a reserved area.
+
+The map provided is guaranteed to list all standard @sc{ram} that should
+be available for normal use.
+
+If bit 7 in the @samp{flags} is set, then the @samp{drives_*} fields
+are valid, and indicate the address of the physical address of the first
+drive structure and the size of drive structures. @samp{drives_addr}
+is the address, and @samp{drives_length} is the total size of drive
+structures. Note that @samp{drives_length} may be zero. Each drive
+structure is formatted as follows:
+
+@example
+@group
+ +-------------------+
+0 | size |
+ +-------------------+
+4 | drive_number |
+ +-------------------+
+5 | drive_mode |
+ +-------------------+
+6 | drive_cylinders |
+8 | drive_heads |
+9 | drive_sectors |
+ +-------------------+
+10 - xx | drive_ports |
+ +-------------------+
+@end group
+@end example
+
+The @samp{size} field specifies the size of this structure. The size
+varies, depending on the number of ports. Note that the size may not be
+equal to (10 + 2 * the number of ports), because of an alignment.
+
+The @samp{drive_number} field contains the BIOS drive number. The
+@samp{drive_mode} field represents the access mode used by the boot
+loader. Currently, the following modes are defined:
+
+@table @samp
+@item 0
+CHS mode (traditional cylinder/head/sector addressing mode).
+
+@item 1
+LBA mode (Logical Block Addressing mode).
+@end table
+
+The three fields, @samp{drive_cylinders}, @samp{drive_heads} and
+@samp{drive_sectors}, indicate the geometry of the drive detected by the
+@sc{bios}. @samp{drive_cylinders} contains the number of the
+cylinders. @samp{drive_heads} contains the number of the
+heads. @samp{drive_sectors} contains the number of the sectors per
+track.
+
+The @samp{drive_ports} field contains the array of the I/O ports used
+for the drive in the @sc{bios} code. The array consists of zero or more
+unsigned two-bytes integers, and is terminated with zero. Note that the
+array may contain any number of I/O ports that are not related to the
+drive actually (such as @sc{dma} controller's ports).
+
+If bit 8 in the @samp{flags} is set, then the @samp{config_table} field
+is valid, and indicates the address of the @sc{rom} configuration table
+returned by the @dfn{GET CONFIGURATION} @sc{bios} call. If the @sc{bios}
+call fails, then the size of the table must be @emph{zero}.
+
+If bit 9 in the @samp{flags} is set, the @samp{boot_loader_name} field
+is valid, and contains the physical address of the name of a boot
+loader booting the kernel. The name is a normal C-style zero-terminated
+string.
+
+If bit 10 in the @samp{flags} is set, the @samp{apm_table} field is
+valid, and contains the physical address of an @sc{apm} table defined as
+below:
+
+@example
+@group
+ +----------------------+
+0 | version |
+2 | cseg |
+4 | offset |
+8 | cseg_16 |
+10 | dseg |
+12 | flags |
+14 | cseg_len |
+16 | cseg_16_len |
+18 | dseg_len |
+ +----------------------+
+@end group
+@end example
+
+The fields @samp{version}, @samp{cseg}, @samp{offset}, @samp{cseg_16},
+@samp{dseg}, @samp{flags}, @samp{cseg_len}, @samp{cseg_16_len},
+@samp{dseg_len} indicate the version number, the protected mode 32-bit
+code segment, the offset of the entry point, the protected mode 16-bit
+code segment, the protected mode 16-bit data segment, the flags, the
+length of the protected mode 32-bit code segment, the length of the
+protected mode 16-bit code segment, and the length of the protected mode
+16-bit data segment, respectively. Only the field @samp{offset} is 4
+bytes, and the others are 2 bytes. See
+@uref{http://www.microsoft.com/hwdev/busbios/amp_12.htm, Advanced Power
+Management (APM) BIOS Interface Specification}, for more information.
+
+If bit 11 in the @samp{flags} is set, the graphics table is available.
+This must only be done if the kernel has indicated in the
+@samp{Multiboot Header} that it accepts a graphics mode.
+
+The fields @samp{vbe_control_info} and @samp{vbe_mode_info} contain
+the physical addresses of @sc{vbe} control information returned by the
+@sc{vbe} Function 00h and @sc{vbe} mode information returned by the
+@sc{vbe} Function 01h, respectively.
+
+The field @samp{vbe_mode} indicates current video mode in the format
+specified in @sc{vbe} 3.0.
+
+The rest fields @samp{vbe_interface_seg}, @samp{vbe_interface_off}, and
+@samp{vbe_interface_len} contain the table of a protected mode interface
+defined in @sc{vbe} 2.0+. If this information is not available, those
+fields contain zero. Note that @sc{vbe} 3.0 defines another protected
+mode interface which is incompatible with the old one. If you want to
+use the new protected mode interface, you will have to find the table
+yourself.
+
+The fields for the graphics table are designed for @sc{vbe}, but
+Multiboot boot loaders may simulate @sc{vbe} on non-@sc{vbe} modes, as
+if they were @sc{vbe} modes.

+@section Notes on PC
+
+In reference to bit 0 of the @samp{flags} parameter in the Multiboot
+information structure, if the bootloader in question uses older
+@sc{bios} interfaces, or the newest ones are not available (see
+description about bit 6), then a maximum of either 15 or 63 megabytes of
+memory may be reported. It is @emph{highly} recommended that boot
+loaders perform a thorough memory probe.
+
+In reference to bit 1 of the @samp{flags} parameter in the Multiboot
+information structure, it is recognized that determination of which
+@sc{bios} drive maps to which device driver in an operating system is
+non-trivial, at best. Many kludges have been made to various operating
+systems instead of solving this problem, most of them breaking under
+many conditions. To encourage the use of general-purpose solutions to
+this problem, there are 2 @sc{bios} device mapping techniques
+(@pxref{BIOS device mapping techniques}).
+
+In reference to bit 6 of the @samp{flags} parameter in the Multiboot
+information structure, it is important to note that the data structure
+used there (starting with @samp{BaseAddrLow}) is the data returned by
+the INT 15h, AX=E820h --- Query System Address Map call. See @xref{Query
+System Address Map, , Query System Address Map, grub.info, The GRUB

+@node BIOS device mapping techniques
+@section BIOS device mapping techniques
+
+Both of these techniques should be usable from any PC operating system,
+and neither require any special support in the drivers themselves. This
+section will be flushed out into detailed explanations, particularly for
+the I/O restriction technique.
+
+The general rule is that the data comparison technique is the quick and
+dirty solution. It works most of the time, but doesn't cover all the
+bases, and is relatively simple.
+
+The I/O restriction technique is much more complex, but it has potential
+to solve the problem under all conditions, plus allow access of the
+remaining @sc{bios} devices when not all of them have operating system
+drivers.
+
+@menu
+* Data comparison technique::
+* I/O restriction technique::
+@end menu
+
+
+@node Data comparison technique
+@subsection Data comparison technique
+
+Before activating @emph{any} of the device drivers, gather enough data
+from similar sectors on each of the disks such that each one can be
+uniquely identified.
+
+After activating the device drivers, compare data from the drives using
+the operating system drivers. This should hopefully be sufficient to
+provide such a mapping.
+
+Problems:
+
+@enumerate
+@item
+The data on some @sc{bios} devices might be identical (so the part
+reading the drives from the @sc{bios} should have some mechanism to give
+up).
+
+@item
+There might be extra drives not accessible from the @sc{bios} which are
+identical to some drive used by the @sc{bios} (so it should be capable
+of giving up there as well).
+@end enumerate
+
+
+@node I/O restriction technique
+@subsection I/O restriction technique
+
+This first step may be unnecessary, but first create copy-on-write
+mappings for the device drivers writing into @sc{pc} @sc{ram}. Keep the
+original copies for the @dfn{clean @sc{bios} virtual machine} to be
+created later.
+
+For each device driver brought online, determine which @sc{bios} devices
+become inaccessible by:
+
+@enumerate
+@item
+Create a @dfn{clean @sc{bios} virtual machine}.
+
+@item
+Set the I/O permission map for the I/O area claimed by the device driver
+to no permissions (neither read nor write).
+
+@item
+Access each device.
+
+@item
+Record which devices succeed, and those which try to access the
+@dfn{restricted} I/O areas (hopefully, this will be an @dfn{xor}
+situation).
+@end enumerate
+
+For each device driver, given how many of the @sc{bios} devices were
+subsumed by it (there should be no gaps in this list), it should be easy
+to determine which devices on the controller these are.
+
+In general, you have at most 2 disks from each controller given
+@sc{bios} numbers, but they pretty much always count from the lowest
+logically numbered devices on the controller.

+@node Example OS code
+@section Example OS code
+
+In this distribution, the example Multiboot kernel @file{kernel} is
+included. The kernel just prints out the Multiboot information structure
+on the screen, so you can make use of the kernel to test a
+Multiboot-compliant boot loader and for reference to how to implement a
+Multiboot kernel. The source files can be found under the directory
+@file{docs} in the GRUB distribution.
+
+The kernel @file{kernel} consists of only three files: @file{boot.S},
+@file{kernel.c} and @file{multiboot.h}. The assembly source
+@file{boot.S} is written in GAS (@pxref{Top, , GNU assembler, as.info,
+The GNU assembler}), and contains the Multiboot information structure to
+comply with the specification. When a Multiboot-compliant boot loader
+loads and execute it, it initialize the stack pointer and @code{EFLAGS},
+and then call the function @code{cmain} defined in @file{kernel.c}. If
+@code{cmain} returns to the callee, then it shows a message to inform
+the user of the halt state and stops forever until you push the reset
+key. The file @file{kernel.c} contains the function @code{cmain},
+which checks if the magic number passed by the boot loader is valid and
+so on, and some functions to print messages on the screen. The file
+@file{multiboot.h} defines some macros, such as the magic number for the
+Multiboot header, the Multiboot header structure and the Multiboot
+information structure.

+% tex foo.texi
+% tex foo.texi
+% dvips foo.dvi -o # or whatever; this makes foo.ps.
+% The extra TeX runs get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble. Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+% @multitable @columnfractions .25 .3 .45
+% @item ...
+%
+% Numbers following @columnfractions are the percent of the total
+% current hsize to be used for each column. You may use as many
+% columns as desired.
+
+
+% Or use a template:
+% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+% @item ...
+% using the widest term desired in each column.
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab do not need to be on their own lines, but it will not hurt
+% if they are.
+
+% Sample multitable:
+
+% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+% @item first col stuff @tab second col stuff @tab third col
+% @item
+% first col stuff
+% @tab
+% second col stuff
+% @tab
+% third col
+% @item first col stuff @tab second col stuff
+% @tab Many paragraphs of text may be used in any column.
+%
+% They will wrap at the width determined by the template.
+% @item@tab@tab This will be in third column.
+% @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+% to baseline.
+% 0pt means it depends on current normal line spacing.

+
+ If an element of ARGV starts with '-', and is not exactly "-" or "--",
+ then it is an option element. The characters of this element
+ (aside from the initial '-') are option characters. If `getopt'
+ is called repeatedly, it returns successively each of the option characters
+ from each of the option elements.
+
+ If `getopt' finds another option character, it returns that character,
+ updating `optind' and `nextchar' so that the next call to `getopt' can
+ resume the scan with the following option character or ARGV-element.
+
+ If there are no more option characters, `getopt' returns -1.
+ Then `optind' is the index in ARGV of the first ARGV-element
+ that is not an option. (The ARGV-elements have been permuted
+ so that those that are not options now come last.)
+
+ OPTSTRING is a string containing the legitimate option characters.
+ If an option character is seen that is not listed in OPTSTRING,
+ return '?' after printing an error message. If you set `opterr' to
+ zero, the error message is suppressed but we still return '?'.
+
+ If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+ so the following text in the same ARGV-element, or the text of the following
+ ARGV-element, is returned in `optarg'. Two colons mean an option that
+ wants an optional arg; if there is text in the current ARGV-element,
+ it is returned in `optarg', otherwise `optarg' is set to zero.
+
+ If OPTSTRING starts with `-' or `+', it requests different methods of
+ handling the non-option ARGV-elements.
+ See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+ Long-named options begin with `--' instead of `-'.
+ Their names may be abbreviated as long as the abbreviation is unique
+ or is an exact match for some defined option. If they have an
+ argument, it follows the option name in the same ARGV-element, separated
+ from the option name by a `=', or else the in next ARGV-element.
+ When `getopt' finds a long-named option, it returns 0 if that option's
+ `flag' field is nonzero, the value of the option's `val' field
+ if the `flag' field is zero.
+
+ The elements of ARGV aren't really const, because we permute them.
+ But we pretend they're const in the prototype to be compatible
+ with other systems.
+
+ LONGOPTS is a vector of `struct option' terminated by an
+ element containing a name which is zero.
+
+ LONGIND returns the index in LONGOPT of the long-named option found.
+ It is only valid when a long-named option has been found by the most
+ recent call.
+
+ If LONG_ONLY is nonzero, '-' as well as '--' can introduce
+ long-named options. */

+
+I OVERVIEW
+
+ The 3c90X series ethernet cards are a group of high-performance busmaster
+ DMA cards from 3Com. This particular driver supports both the 3c90x and
+ the 3c90xB revision cards. 3C90xC family support has been tested to some
+ degree but not extensively.
+
+ Here's the licensing information:
+
+ This program Copyright (C) 1999 LightSys Technology Services, Inc.
+ Portions Copyright (C) 1999 Steve Smith.
+

+ sold, or copied for any purpose, provided that the above copyright message
+ and this text are included with all source copies or derivative works, and
+ provided that the above copyright message and this text are included in the
+ documentation of any binary-only distributions. This program is
+ distributed WITHOUT ANY WARRANTY, without even the warranty of FITNESS FOR
+ A PARTICULAR PURPOSE or MERCHANTABILITY. Please read the associated
+ documentation "3c90x.txt" before compiling and using this driver.
+
+
+II FLASH PROMS
+
+ The 3c90xB cards, according to the 3Com documentation, only accept the
+ following flash memory chips:
+
+ Atmel AT29C512 (64 kilobyte)
+ Atmel AT29C010 (128 kilobyte)
+
+ The 3c90x cards, according to the 3Com documentation, accept the
+ following flash memory chips capacities:
+
+ 64 kb (8 kB)
+ 128 kb (16 kB)
+ 256 kb (32 kB) and
+ 512 kb (64 kB)
+
+ Atmel AT29C512 (64 kilobyte) chips are specifically listed for both
+ adapters, but flashing on the 3c905b cards would only be supported
+ through the Atmel parts. Any device, of the supported size, should
+ be supported when programmed by a dedicated PROM programmer (e.g.
+ not the card).
+
+ To use this driver in such a PROM, visit Atmel's web site and download
+ their .PDF file containing a list of their distributors. Contact the
+ distributors for pricing information. The prices are quite reasonable
+ (about $3 US each for the 64 kB part), and are comparable to what one would
+ expect for similarly sized standard EPROMs. And, the flash chips are much
+ easier to work with, as they don't need to be UV-erased to be reprogrammed.
+ The 3C905B card actually provides a method to program the flash memory
+ while it is resident on board the card itself; if someone would like to
+ write a small DOS program to do the programming, I can provide the
+ information about the registers and so forth.
+
+ A utility program, 3c90xutil, is provided with Etherboot in the 'contrib'
+ directory that allows for the on-board flashing of the ROM while Linux
+ is running. The program has been successfully used under Linux, but I
+ have heard problem reports of its use under FreeBSD. Anyone willing to
+ make it work under FreeBSD is more than welcome to do so!
+
+ You also have the option of using EPROM chips - the 3C905B-TX-NM has been
+ successfully tested with 27C256 (32kB) and 27C512 (64kB) chips with a
+ specified access time of 100ns and faster.
+
+
+III GENERAL USE
+
+ Normally, the basic procedure for using this driver is as follows:
+
+ 1. Run the 3c90xcfg program on the driver diskette to enable the
+ boot PROM and set it to 64k or 128k, as appropriate.
+ 2. Build the appropriate 3c90x.fd0 or 3c90x.fd0 floppy image with
+ possibly the value CFG_3C90X_XCVR defined to the transceiver type that
+ you want to use (i.e., 10/100 rj45, AUI, coax, MII).
+ 3. Run the floppy image on the PC to be network booted, to get
+ it configured, and to verify that it will boot properly.
+ 4. Build the 3c90x.rom or 3c90x.lzrom PROM image and program
+ it into the flash or EPROM memory chip.
+ 5. Put the PROM in the ethernet card, boot and enable 'boot from
+ network first' in the system BIOS, save and reboot.
+
+ Here are some issues to be aware of:
+
+ 1. If you experience crashes or different behaviour when using the
+ boot PROM, add the setting CFG_3C90X_BOOTROM_FIX and go through the
+ steps 2-5 above. This works around a bug in some 3c905B cards (see
+ below), but has some side-effects which may not be desirable.
+ Please note that you have to boot off a floppy (not PROM!) once for
+ this fix to take effect.
+ 2. The possible need to manually set the CFG_3C90X_XCVR value to
+ configure the transceiver type. Values are listed below.
+ 3. The possible need to define CFG_3C90X_PRESERVE_XCVR for use in
+ operating systems that don't intelligently determine the
+ transceiver type.
+
+ Some things that are on the 'To-Do' list, perhaps for me, but perhaps
+ for any other volunteers out there:
+
+ 1. Extend the driver to fully implement the auto-select
+ algorithm if the card has multiple media ports.
+ 2. Fix any bugs in the code <grin>....
+ 3. Extend the driver to support the 3c905c revision cards
+ "officially". Right now, the support has been primarily empirical
+ and not based on 3c905C documentation.
+
+ Now for the details....
+
+ This driver has been tested on roughly 300 systems. The main two
+ configuration issues to contend with are:
+
+ 1. Ensure that PCI Busmastering is enabled for the adapter (configured
+ in the CMOS setup)
+ 2. Some systems don't work properly with the adapter when plug and
+ play OS is enabled; I always set it to "No" or "Disabled" -- this makes
+ it easier and really doesn't adversely affect anything.
+
+ Roughly 95% of the systems worked when configured properly. A few
+ have issues with booting locally once the boot PROM has been installed
+ (this number has been less than 2%). Other configuration issues that
+ to check:
+
+ 1. Newer BIOS's actually work correctly with the network boot order.
+ Set the network adapter first. Most older BIOS's automatically go to
+ the network boot PROM first.
+ 2. For systems where the adapter was already installed and is just
+ having the PROM installed, try setting the "reset configuration data"
+ to yes in the CMOS setup if the BIOS isn't seen at first. If your BIOS
+ doesn't have this option, remove the card, start the system, shut down,
+ install the card and restart (or switch to a different PCI slot).
+ 3. Make sure the CMOS security settings aren't preventing a boot.
+
+ The 3c905B cards have a significant 'bug' that relates to the flash prom:
+ unless the card is set internally to the MII transceiver, it will only
+ read the first 8k of the PROM image. Don't ask why -- it seems really
+ obscure, but it has to do with the way they mux'd the address lines
+ from the PCI bus to the ROM. Unfortunately, most of us are not using
+ MII transceivers, and even the .lzrom image ends up being just a little
+ bit larger than 8k. Note that the workaround for this is disabled by
+ default, because the Windows NT 4.0 driver does not like it (no packets
+ are transmitted).
+
+ So, the solution that I've used is to internally set the card's nvram
+ configuration to use MII when it boots. The 3c905b driver does this
+ automatically. This way, the 16k prom image can be loaded into memory,
+ and then the 3c905b driver can set the temporary configuration of the
+ card to an appropriate value, either configurable by the user or chosen
+ by the driver.
+
+ To enable the 3c905B bugfix, which is necessary for these cards when
+ booting from the Flash ROM, define -DCFG_3C90X_BOOTROM_FIX when building,
+ create a floppy image and boot it once.
+ Thereafter, the card should accept the larger prom image.
+
+ The driver should choose an appropriate transceiver on the card. However,
+ if it doesn't on your card or if you need to, for instance, set your
+ card to 10mbps when connected to an unmanaged 10/100 hub, you can specify
+ which transceiver you want to use. To do this, build the 3c905b.fd0
+ image with -DCFG_3C90X_XCVR=x, where 'x' is one of the following
+ values:
+
+ 0 10Base-T
+ 1 10mbps AUI
+ 3 10Base-2 (thinnet/coax)
+ 4 100Base-TX
+ 5 100Base-FX
+ 6 MII
+ 8 Auto-negotiation 10Base-T / 100Base-TX (usually the default)
+ 9 MII External MAC Mode
+ 255 Allow driver to choose an 'appropriate' media port.
+
+ Then proceed from step 2 in the above 'general use' instructions. The
+ .rom image can be built with CFG_3C90X_XCVR set to a value, but you
+ normally don't want to do this, since it is easier to change the
+ transceiver type by rebuilding a new floppy, changing the BIOS to floppy
+ boot, booting, and then changing the BIOS back to network boot. If
+ CFG_3C90X_XCVR is not set in a particular build, it just uses the
+ current configuration (either its 'best guess' or whatever the stored
+ CFG_3C90X_XCVR value was from the last time it was set).
+
+ [[ Note for the more technically inclined: The CFG_3C90X_XCVR value is
+ programmed into a register in the card's NVRAM that was reserved for
+ LanWorks PROM images to use. When the driver boots, the card comes
+ up in MII mode, and the driver checks the LanWorks register to find
+ out if the user specified a transceiver type. If it finds that
+ information, it uses that, otherwise it picks a transceiver that the
+ card has based on the 3c905b's MediaOptions register. This driver isn't
+ quite smart enough to always determine which media port is actually
+ _connected_; maybe someone else would like to take on that task (it
+ actually involves sending a self-directed packet and seeing if it
+ comes back. IF it does, that port is connected). ]]
+
+ Another issue to keep in mind is that it is possible that some OS'es
+ might not be happy with the way I've handled the PROM-image hack with
+ setting MII mode on bootup. Linux 2.0.35 does not have this problem.
+ Behavior of other systems may vary. The 3com documentation specifically
+ says that, at least with the card that I have, the device driver in the
+ OS should auto-select the media port, so other drivers should work fine
+ with this 'hack'. However, if yours doesn't seem to, you can try defining
+ CFG_3C90X_PRESERVE_XCVR when building to cause Etherboot to keep the
+ working setting (that allowed the bootp/tftp process) across the eth_reset
+ operation.
+
+
+IV FOR DEVELOPERS....
+
+ If you would like to fix/extend/etc. this driver, feel free to do so; just
+ be sure you can test the modified version on the 3c905B-TX cards that the
+ driver was originally designed for. This section of this document gives
+ some information that might be relevant to a programmer.
+
+ A. Main Entry Point

+ a3c90x_probe is the main entry point for this driver. It is referred
+ to in an array in 'config.c'.

+
+ The functions a3c90x_transmit, a3c90x_poll, a3c90x_reset, and
+ a3c90x_disable are static functions that EtherBoot finds out about
+ as a result of a3c90x_probe setting entries in the nic structure
+ for them. The EtherBoot framework does not use interrupts. It is
+ polled. All transmit and receive operations are initiated by the
+ etherboot framework, not by an interrupt or by the driver.
+
+ C. Internal Functions
+
+ The following functions are internal to the driver:
+
+ a3c90x_internal_IssueCommand - sends a command to the 3c905b card.
+ a3c90x_internal_SetWindow - shifts between one of eight register
+ windows onboard the 3c90x. The bottom 16 bytes of the card's
+ I/O space are multiplexed among 128 bytes, only 16 of which are
+ visible at any one time. This SetWindow function selects one of
+ the eight sets.
+ a3c90x_internal_ReadEeprom - reads a word (16 bits) from the
+ card's onboard nvram. This is NOT the BIOS boot rom. This is
+ where the card stores such things as its hardware address.
+ a3c90x_internal_WriteEeprom - writes a word (16 bits) to the
+ card's nvram, and recomputes the eeprom checksum.
+ a3c90x_internal_WriteEepromWord - writes a word (16 bits) to the
+ card's nvram. Used by the above routine.
+ a3c90x_internal_WriteEepromWord - writes a word (16 bits) to the
+ card's nvram. Used by the above routine.
+
+ D. Globals
+
+ All global variables are inside a global structure named INF_3C90X.
+ So, wherever you see that structure referenced, you know the variable
+ is a global. Just keeps things a little neater.
+
+ E. Enumerations
+
+ There are quite a few enumerated type definitions for registers and
+ so forth, many for registers that I didn't even touch in the driver.
+ Register types start with 'reg', window numbers (for SetWindow)
+ start with 'win', and commands (for IssueCommand) start with 'cmd'.
+ Register offsets also include an indication in the name as to the
+ size of the register (_b = byte, _w = word, _l = long), and which
+ window the register is in, if it is windowed (0-7).
+
+ F. Why the 'a3c90x' name?
+
+ I had to come up with a letter at the beginning of all of the
+ identifiers, since 3com so conveniently had their name start with a
+ number. Another driver used 't' (for 'three'?); I chose 'a' for
+ no reason at all.
+
+Addendum by Jorge L. deLyra <delyra@latt.if.usp.br>, 22Nov2000 re
+working around the 3C905 hardware bug mentioned above:
+
+Use this floppy to fix any 3COM model 3C905B PCI 10/100 Ethernet cards
+that fail to load and run the boot program the first time around. If
+they have a "Lucent" rather than a "Broadcom" chipset these cards have
+a configuration bug that causes a hang when trying to load the boot
+program from the PROM, if you try to use them right out of the box.
+
+The boot program in this floppy is the file named 3c905b-tpo100.rom
+from Etherboot version 4.6.10, compiled with the bugfix parameter
+
+ CFG_3C90X_BOOTROM_FIX
+
+You have to take the chip off the card and boot the system once using
+this floppy. Once loaded from the floppy, the boot program will access
+the card and change some setting in it, correcting the problem. After
+that you may use either this boot program or the normal one, compiled
+without this bugfix parameter, to boot the machine from the PROM chip.
+
+[Any recent Etherboot version should do, not just 4.6.10 - Ed.]

+You can use the netboot support to download OS images from a network.
+Nearly all the device drivers are coming from the network-based boot
+loader, Etherboot. Please visit its web page. They have rich
+documentations so you will be able to get useful information from there.
+The URL is <http://etherboot.sourceforge.net/>.
+
+These below are common options for configure. Perhaps you may not need
+to specify them.
+
+--disable-packet-retransmission
+ Turns off packet retransmission. Use it on an empty network, where
+ no packet collision can happen.
+
+--enable-pci-direct
+ Define this for PCI BIOSes that do not implement BIOS32 or not
+ correctly.
+
+--enable-diskless
+ Enable the diskless support. If specified, you will get two optional
+ images, called "nbgrub" and "pxegrub". The former is the ``Net Boot
+ Image Proposal'' format, which is used by Etherboot and Netboot, while
+ the latter is the ``Preboot Execution Environment" format, which is
+ used by a PXE ROM. You may buy a PXE ROM from some companies.
+
+Here is the information about the device drivers. They are all disabled
+by default, so you must specify configure options to enable drivers you
+want to use. Some drivers have extra per-driver options, so the extra
+options are also described below.
+
+Caution: You should enable them as you need. Don't enable any
+unnecessary driver, because GRUB might crash if you include too many
+drivers at the same time.

+
+ Thu Dec 6 22:40:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
+
+ * disabled all "advanced" features; this should make the code more reliable

+ * some cosmetic changes
+

+
+ Thu Dec 5 21:00:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
+
+ * tested the code against a CS8900 card
+
+ * lots of minor bug fixes and adjustments
+
+ * this is the first release, that actually works! it still requires some
+ changes in order to be more tolerant to different environments
+
+ * 4
+
+ Fri Nov 22 23:00:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
+
+ * read the manuals for the CS89x0 chipsets and took note of all the
+ changes that will be neccessary in order to adapt Russel Nelson's code
+ to the requirements of a BOOT-Prom
+
+ * 6
+
+ Thu Nov 19 22:00:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
+
+ * Synched with Russel Nelson's current code (v1.00)
+
+ * 2
+
+ Thu Nov 12 18:00:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>

+ Copyright 1994 David C. Davies

+
+
+ This software may be used and distributed according to the terms of

+
+ This driver is written for the Digital Equipment Corporation series
+ of DEPCA and EtherWORKS ethernet cards:
+
+ DEPCA (the original)
+ DE100
+ DE101
+ DE200 Turbo
+ DE201 Turbo
+ DE202 Turbo (TP BNC)
+ DE210
+ DE422 (EISA)
+
+ The driver has been tested on DE100, DE200 and DE202 cards in a
+ relatively busy network. The DE422 has been tested a little.
+
+ This driver will NOT work for the DE203, DE204 and DE205 series of
+ cards, since they have a new custom ASIC in place of the AMD LANCE
+ chip. See the 'ewrk3.c' driver in the Linux source tree for running
+ those cards.
+
+ I have benchmarked the driver with a DE100 at 595kB/s to (542kB/s from)
+ a DECstation 5000/200.
+
+ The author may be reached at davies@maniac.ultranet.com
+
+ =========================================================================
+
+ The driver was originally based on the 'lance.c' driver from Donald
+ Becker which is included with the standard driver distribution for
+ linux. V0.4 is a complete re-write with only the kernel interface
+ remaining from the original code.

+
+ Peter Bauer's depca.c (V0.5) was referred to when debugging V0.1 of this
+ driver.
+
+ The original DEPCA card requires that the ethernet ROM address counter
+ be enabled to count and has an 8 bit NICSR. The ROM counter enabling is
+ only done when a 0x08 is read as the first address octet (to minimise
+ the chances of writing over some other hardware's I/O register). The
+ NICSR accesses have been changed to byte accesses for all the cards
+ supported by this driver, since there is only one useful bit in the MSB
+ (remote boot timeout) and it is not used. Also, there is a maximum of
+ only 48kB network RAM for this card. My thanks to Torbjorn Lindh for
+ help debugging all this (and holding my feet to the fire until I got it
+ right).
+
+ The DE200 series boards have on-board 64kB RAM for use as a shared
+ memory network buffer. Only the DE100 cards make use of a 2kB buffer
+ mode which has not been implemented in this driver (only the 32kB and
+ 64kB modes are supported [16kB/48kB for the original DEPCA]).
+
+ At the most only 2 DEPCA cards can be supported on the ISA bus because
+ there is only provision for two I/O base addresses on each card (0x300
+ and 0x200). The I/O address is detected by searching for a byte sequence
+ in the Ethernet station address PROM at the expected I/O address for the
+ Ethernet PROM. The shared memory base address is 'autoprobed' by
+ looking for the self test PROM and detecting the card name. When a
+ second DEPCA is detected, information is placed in the base_addr
+ variable of the next device structure (which is created if necessary),
+ thus enabling ethif_probe initialization for the device. More than 2
+ EISA cards can be supported, but care will be needed assigning the
+ shared memory to ensure that each slot has the correct IRQ, I/O address
+ and shared memory address assigned.
+
+ ************************************************************************
+
+ NOTE: If you are using two ISA DEPCAs, it is important that you assign
+ the base memory addresses correctly. The driver autoprobes I/O 0x300
+ then 0x200. The base memory address for the first device must be less
+ than that of the second so that the auto probe will correctly assign the
+ I/O and memory addresses on the same card. I can't think of a way to do
+ this unambiguously at the moment, since there is nothing on the cards to
+ tie I/O and memory information together.
+
+ I am unable to test 2 cards together for now, so this code is
+ unchecked. All reports, good or bad, are welcome.
+
+ ************************************************************************
+
+ The board IRQ setting must be at an unused IRQ which is auto-probed
+ using Donald Becker's autoprobe routines. DEPCA and DE100 board IRQs are
+ {2,3,4,5,7}, whereas the DE200 is at {5,9,10,11,15}. Note that IRQ2 is
+ really IRQ9 in machines with 16 IRQ lines.
+
+ No 16MB memory limitation should exist with this driver as DMA is not
+ used and the common memory area is in low memory on the network card (my
+ current system has 20MB and I've not had problems yet).
+
+ The ability to load this driver as a loadable module has been added. To
+ utilise this ability, you have to do <8 things:
+
+ 0) have a copy of the loadable modules code installed on your system.
+ 1) copy depca.c from the /linux/drivers/net directory to your favourite
+ temporary directory.
+ 2) if you wish, edit the source code near line 1530 to reflect the I/O
+ address and IRQ you're using (see also 5).
+ 3) compile depca.c, but include -DMODULE in the command line to ensure
+ that the correct bits are compiled (see end of source code).
+ 4) if you are wanting to add a new card, goto 5. Otherwise, recompile a
+ kernel with the depca configuration turned off and reboot.
+ 5) insmod depca.o [irq=7] [io=0x200] [mem=0xd0000] [adapter_name=DE100]
+ [Alan Cox: Changed the code to allow command line irq/io assignments]
+ [Dave Davies: Changed the code to allow command line mem/name
+ assignments]
+ 6) run the net startup bits for your eth?? interface manually
+ (usually /etc/rc.inet[12] at boot time).
+ 7) enjoy!
+
+ Note that autoprobing is not allowed in loadable modules - the system is
+ already up and running and you're messing with interrupts.
+
+ To unload a module, turn off the associated interface
+ 'ifconfig eth?? down' then 'rmmod depca'.
+
+ To assign a base memory address for the shared memory when running as a
+ loadable module, see 5 above. To include the adapter name (if you have
+ no PROM but know the card name) also see 5 above. Note that this last
+ option will not work with kernel built-in depca's.
+
+ The shared memory assignment for a loadable module makes sense to avoid
+ the 'memory autoprobe' picking the wrong shared memory (for the case of
+ 2 depca's in a PC).
+
+ ************************************************************************
+ Support for MCA EtherWORKS cards added 11-3-98.
+ Verified to work with up to 2 DE212 cards in a system (although not
+ fully stress-tested).
+
+ Currently known bugs/limitations:
+
+ Note: with the MCA stuff as a module, it trusts the MCA configuration,
+ not the command line for IRQ and memory address. You can
+ specify them if you want, but it will throw your values out.
+ You still have to pass the IO address it was configured as
+ though.

+/**************************************************************************
+Etherboot - BOOTP/TFTP Bootstrap Program
+Intel EEPRO/10 NIC driver for Etherboot
+Adapted from Linux eepro.c from kernel 2.2.17
+
+This board accepts a 32 pin EEPROM (29C256), however a test with a
+27C010 shows that this EPROM also works in the socket, but it's not clear
+how repeatably. The two top address pins appear to be held low, thus
+the bottom 32kB of the 27C010 is visible in the CPU's address space.
+To be sure you could put 4 copies of the code in the 27C010, then
+it doesn't matter whether the extra lines are held low or high, just
+hopefully not floating as CMOS chips don't like floating inputs.
+
+Be careful with seating the EPROM as the socket on my board actually
+has 34 pins, the top row of 2 are not used.

+ *
+ * This is the etherboot intel etherexpress Pro/100B driver.
+ *
+ * It was written from scratch, with Donald Beckers eepro100.c kernel
+ * driver as a guideline. Mostly the 82557 related definitions and the
+ * lower level routines have been cut-and-pasted into this source.
+ *
+ * The driver was finished before Intel got the NDA out of the closet.
+ * I still don't have the docs.
+ * */
+
+/* Philosophy of this driver.
+ *
+ * Probing:
+ *
+ * Using the pci.c functions of the Etherboot code, the 82557 chip is detected.
+ * It is verified that the BIOS initialized everything properly and if
+ * something is missing it is done now.
+ *
+ *
+ * Initialization:
+ *
+ *
+ * The chip is then initialized to "know" its ethernet address, and to
+ * start recieving packets. The Linux driver has a whole transmit and
+ * recieve ring of buffers. This is neat if you need high performance:
+ * you can write the buffers asynchronously to the chip reading the
+ * buffers and transmitting them over the network. Performance is NOT
+ * an issue here. We can boot a 400k kernel in about two
+ * seconds. (Theory: 0.4 seconds). Booting a system is going to take
+ * about half a minute anyway, so getting 10 times closer to the
+ * theoretical limit is going to make a difference of a few percent.
+ *
+ *
+ * Transmitting and recieving.
+ *
+ * We have only one transmit descriptor. It has two buffer descriptors:
+ * one for the header, and the other for the data.
+ * We have only one receive buffer. The chip is told to recieve packets,
+ * and suspend itself once it got one. The recieve (poll) routine simply
+ * looks at the recieve buffer to see if there is already a packet there.
+ * if there is, the buffer is copied, and the reciever is restarted.
+ *
+ * Caveats:
+ *
+ * The etherboot framework moves the code to the 32k segment from
+ * 0x98000 to 0xa0000. There is just a little room between the end of
+ * this driver and the 0xa0000 address. If you compile in too many
+ * features, this will overflow.
+ * The number under "hex" in the output of size that scrolls by while
+ * compiling should be less than 8000. Maybe even the stack is up there,
+ * so that you need even more headroom.
+ */
+
+/* The etherboot authors seem to dislike the argument ordering in
+ * outb macros that Linux uses. I disklike the confusion that this
+ * has caused even more.... This file uses the Linux argument ordering. */

+ program space than initializing the individual tables, and I feel it's much
+ cleaner.
+
+ The databook is particularly useless for the first two structures, I had
+ to use the Crynwr driver as an example.
+

+/*
+ That's it: only 86 bytes to set up the beast, including every extra
+ command available. The 170 byte buffer at DUMP_DATA is shared between the
+ Dump command (called only by the diagnostic program) and the SetMulticastList
+ command.
+
+ To complete the memory setup you only have to write the station address at
+ SA_OFFSET and create the Tx & Rx buffer lists.
+
+ The Tx command chain and buffer list is setup as follows:
+ A Tx command table, with the data buffer pointing to...
+ A Tx data buffer descriptor. The packet is in a single buffer, rather than
+ chaining together several smaller buffers.
+ A NoOp command, which initially points to itself,
+ And the packet data.
+
+ A transmit is done by filling in the Tx command table and data buffer,
+ re-writing the NoOp command, and finally changing the offset of the last
+ command to point to the current Tx command. When the Tx command is finished,
+ it jumps to the NoOp, when it loops until the next Tx command changes the
+ "link offset" in the NoOp. This way the 82586 never has to go through the
+ slow restart sequence.
+
+ The Rx buffer list is set up in the obvious ring structure. We have enough
+ memory (and low enough interrupt latency) that we can avoid the complicated
+ Rx buffer linked lists by alway associating a full-size Rx data buffer with
+ each Rx data frame.
+
+ I currently use one transmit buffer starting at TX_BUF_START (0x0100), and
+ use the rest of memory, from RX_BUF_START to RX_BUF_END, for Rx buffers.

+
+ Known to work on DEC DE500 using 21143-PC chipset.
+ Even on cards with the same chipset there can be
+ incompatablity problems with the way media selection
+ and status LED settings are done. See comments below.
+
+ Some code fragments were taken from verious places,
+ Ken Yap's etherboot, FreeBSD's if_de.c, and various
+ Linux related files. DEC's manuals for the 21143 and
+ SROM format were very helpful. The Linux de driver
+ development page has a number of links to useful
+ related information. Have a look at:
+ ftp://cesdis.gsfc.nasa.gov/pub/linux/drivers/tulip-devel.html

+ 06 Apr 2001 ken_yap@users.sourceforge.net (Ken Yap)
+ Following email from Hyun-Joon Cha, added a disable routine, otherwise
+ NIC remains live and can crash the kernel later.
+
+ 4 Feb 2000 espenlaub@informatik.uni-ulm.de (Klaus Espenlaub)
+ Shuffled things around, removed the leftovers from the 8129 support
+ that was in the Linux driver and added a bit more 8139 definitions.
+ Moved the 8K receive buffer to a fixed, available address outside the
+ 0x98000-0x9ffff range. This is a bit of a hack, but currently the only
+ way to make room for the Etherboot features that need substantial amounts
+ of code like the ANSI console support. Currently the buffer is just below
+ 0x10000, so this even conforms to the tagged boot image specification,
+ which reserves the ranges 0x00000-0x10000 and 0x98000-0xA0000. My
+ interpretation of this "reserved" is that Etherboot may do whatever it
+ likes, as long as its environment is kept intact (like the BIOS
+ variables). Hopefully fixed rtl_poll() once and for all. The symptoms
+ were that if Etherboot was left at the boot menu for several minutes, the
+ first eth_poll failed. Seems like I am the only person who does this.
+ First of all I fixed the debugging code and then set out for a long bug
+ hunting session. It took me about a week full time work - poking around
+ various places in the driver, reading Don Becker's and Jeff Garzik's Linux
+ driver and even the FreeBSD driver (what a piece of crap!) - and
+ eventually spotted the nasty thing: the transmit routine was acknowledging
+ each and every interrupt pending, including the RxOverrun and RxFIFIOver
+ interrupts. This confused the RTL8139 thoroughly. It destroyed the
+ Rx ring contents by dumping the 2K FIFO contents right where we wanted to
+ get the next packet. Oh well, what fun.
+
+ 18 Jan 2000 mdc@thinguin.org (Marty Connor)
+ Drastically simplified error handling. Basically, if any error
+ in transmission or reception occurs, the card is reset.
+ Also, pointed all transmit descriptors to the same buffer to
+ save buffer space. This should decrease driver size and avoid
+ corruption because of exceeding 32K during runtime.
+
+ 28 Jul 1999 (Matthias Meixner - meixner@rbg.informatik.tu-darmstadt.de)
+ rtl_poll was quite broken: it used the RxOK interrupt flag instead
+ of the RxBufferEmpty flag which often resulted in very bad
+ transmission performace - below 1kBytes/s.

+How I added the SIS900 card to Etherboot
+
+Author: Marty Connor (mdc@thinguin.org)
+
+Date: 25 Febrary 2001
+
+Description:
+
+This file is intended to help people who want to write an Etherboot
+driver or port another driver to Etherboot. It is a starting point.
+Perhaps someday I may write a more detailed description of writing an
+Etherboot driver. This text should help get people started, and
+studying sis900.[ch] should help show the basic structure and
+techniques involved in writing and Etherboot driver.
+
+***********************************************************************
+
+0. Back up all the files I need to modify:
+
+cd etherboot-4.7.20/src
+cp Makefile Makefile.orig
+cp config.c config.c.orig
+cp pci.h pci.h.orig
+cp NIC NIC.orig
+cp cards.h cards.h.orig
+
+1. Edit src/Makefile to add SIS900FLAGS to defines
+
+SIS900FLAGS= -DINCLUDE_SIS900
+
+2. edit src/pci.h to add PCI signatures for card
+
+#define PCI_VENDOR_ID_SIS 0x1039
+#define PCI_DEVICE_ID_SIS900 0x0900
+#define PCI_DEVICE_ID_SIS7016 0x7016
+
+3. Edit src/config.c to add the card to the card probe list
+
+#if defined(INCLUDE_NS8390) || defined(INCLUDE_EEPRO100) ||
+ defined(INCLUDE_LANCE) || defined(INCLUDE_EPIC100) ||

+#endif
+
+... and ...
+
+#ifdef INCLUDE_SIS900
+ { "SIS900", sis900_probe, pci_ioaddrs },
+#endif
+
+4. Edit NIC to add sis900 and sis7016 to NIC list
+
+# SIS 900 and SIS 7016
+sis900 sis900 0x1039,0x0900
+sis7016 sis900 0x1039,0x7016
+
+5. Edit cards.h to add sis900 probe routine declaration
+
+#ifdef INCLUDE_SIS900
+extern struct nic *sis900_probe(struct nic *, unsigned short *
+ PCI_ARG(struct pci_device *));
+#endif

+
+At this point, you can begin creating your driver source file. See
+the "Writing and Etherboot Driver" section of the Etherboot
+documentation for some hints. See the skel.c file for a starting
+point. If there is a Linux driver for the card, you may be able to
+use that. Copy and learn from existing Etherboot drivers (this is GPL
+/ Open Source software!).
+
+Join the etherboot-developers and etherboot-users mailing lists
+(information is on etherboot.sourceforge.net) for information and
+assistance. We invite more developers to help improve Etherboot.

+ * The Schneider & Koch (SK) G16 Network device driver is based

+ * R. Bolz (Schneider & Koch, Germany)
+ *
+ * See README.sk_g16 for details about limitations and bugs for the
+ * current version.
+ *
+ * To Do:
+ * - Support of SK_G8 and other SK Network Cards.
+ * - Autoset memory mapped RAM. Check for free memory and then
+ * configure RAM correctly.
+ * - SK_close should really set card in to initial state.
+ * - Test if IRQ 3 is not switched off. Use autoirq() functionality.
+ * (as in /drivers/net/skeleton.c)
+ * - Implement Multicast addressing. At minimum something like
+ * in depca.c.
+ * - Redo the statistics part.
+ * - Try to find out if the board is in 8 Bit or 16 Bit slot.
+ * If in 8 Bit mode don't use IRQ 11.
+ * - (Try to make it slightly faster.)

+ * Change History
+ *
+ * Tigran Aivazian <tigran@sco.com>: TLan_PciProbe() now uses
+ * new PCI BIOS interface.
+ * Alan Cox <alan@redhat.com>: Fixed the out of memory
+ * handling.
+ *
+ * Torben Mathiasen <torben.mathiasen@compaq.com> New Maintainer!
+ *
+ * v1.1 Dec 20, 1999 - Removed linux version checking
+ * Patch from Tigran Aivazian.
+ * - v1.1 includes Alan's SMP updates.
+ * - We still have problems on SMP though,
+ * but I'm looking into that.
+ *
+ * v1.2 Jan 02, 2000 - Hopefully fixed the SMP deadlock.
+ * - Removed dependency of HZ being 100.
+ * - We now allow higher priority timers to
+ * overwrite timers like TLAN_TIMER_ACTIVITY
+ * Patch from John Cagle <john.cagle@compaq.com>.
+ * - Fixed a few compiler warnings.
+ *
+ * v1.3 Feb 04, 2000 - Fixed the remaining HZ issues.
+ * - Removed call to pci_present().
+ * - Removed SA_INTERRUPT flag from irq handler.
+ * - Added __init and __initdata to reduce resisdent
+ * code size.
+ * - Driver now uses module_init/module_exit.
+ * - Rewrote init_module and tlan_probe to
+ * share a lot more code. We now use tlan_probe
+ * with builtin and module driver.
+ * - Driver ported to new net API.
+ * - tlan.txt has been reworked to reflect current
+ * driver (almost)
+ * - Other minor stuff
+ *
+ * v1.4 Feb 10, 2000 - Updated with more changes required after Dave's
+ * network cleanup in 2.3.43pre7 (Tigran & myself)
+ * - Minor stuff.
+ *
+ * v1.5 March 22, 2000 - Fixed another timer bug that would hang the driver
+ * if no cable/link were present.
+ * - Cosmetic changes.
+ * - TODO: Port completely to new PCI/DMA API
+ * Auto-Neg fallback.
+ *
+ * v1.6 April 04, 2000 - Fixed driver support for kernel-parameters. Haven't
+ * tested it though, as the kernel support is currently
+ * broken (2.3.99p4p3).
+ * - Updated tlan.txt accordingly.
+ * - Adjusted minimum/maximum frame length.
+ * - There is now a TLAN website up at
+ * http://tlan.kernel.dk
+ *
+ * v1.7 April 07, 2000 - Started to implement custom ioctls. Driver now
+ * reports PHY information when used with Donald
+ * Beckers userspace MII diagnostics utility.
+ *
+ * v1.8 April 23, 2000 - Fixed support for forced speed/duplex settings.
+ * - Added link information to Auto-Neg and forced
+ * modes. When NIC operates with auto-neg the driver
+ * will report Link speed & duplex modes as well as
+ * link partner abilities. When forced link is used,
+ * the driver will report status of the established
+ * link.
+ * Please read tlan.txt for additional information.
+ * - Removed call to check_region(), and used
+ * return value of request_region() instead.
+ *
+ * v1.8a May 28, 2000 - Minor updates.
+ *
+ * v1.9 July 25, 2000 - Fixed a few remaining Full-Duplex issues.
+ * - Updated with timer fixes from Andrew Morton.
+ * - Fixed module race in TLan_Open.
+ * - Added routine to monitor PHY status.
+ * - Added activity led support for Proliant devices.
+ *
+ * v1.10 Aug 30, 2000 - Added support for EISA based tlan controllers
+ * like the Compaq NetFlex3/E.
+ * - Rewrote tlan_probe to better handle multiple
+ * bus probes. Probing and device setup is now
+ * done through TLan_Probe and TLan_init_one. Actual
+ * hardware probe is done with kernel API and
+ * TLan_EisaProbe.
+ * - Adjusted debug information for probing.
+ * - Fixed bug that would cause general debug information
+ * to be printed after driver removal.
+ * - Added transmit timeout handling.
+ * - Fixed OOM return values in tlan_probe.
+ * - Fixed possible mem leak in tlan_exit
+ * (now tlan_remove_one).
+ * - Fixed timer bug in TLan_phyMonitor.
+ * - This driver version is alpha quality, please
+ * send me any bug issues you may encounter.
+ *
+ * v1.11 Aug 31, 2000 - Do not try to register irq 0 if no irq line was
+ * set for EISA cards.
+ * - Added support for NetFlex3/E with nibble-rate
+ * 10Base-T PHY. This is untestet as I haven't got
+ * one of these cards.
+ * - Fixed timer being added twice.
+ * - Disabled PhyMonitoring by default as this is
+ * work in progress. Define MONITOR to enable it.
+ * - Now we don't display link info with PHYs that
+ * doesn't support it (level1).
+ * - Incresed tx_timeout beacuse of auto-neg.
+ * - Adjusted timers for forced speeds.
+ *
+ * v1.12 Oct 12, 2000 - Minor fixes (memleak, init, etc.)
+ *
+ * v1.13 Nov 28, 2000 - Stop flooding console with auto-neg issues
+ * when link can't be established.
+ * - Added the bbuf option as a kernel parameter.
+ * - Fixed ioaddr probe bug.
+ * - Fixed stupid deadlock with MII interrupts.
+ * - Added support for speed/duplex selection with
+ * multiple nics.
+ * - Added partly fix for TX Channel lockup with
+ * TLAN v1.0 silicon. This needs to be investigated
+ * further.
+ *
+ * v1.14 Dec 16, 2000 - Added support for servicing multiple frames per.
+ * interrupt. Thanks goes to
+ * Adam Keys <adam@ti.com>
+ * Denis Beaudoin <dbeaudoin@ti.com>
+ * for providing the patch.
+ * - Fixed auto-neg output when using multiple
+ * adapters.
+ * - Converted to use new taskq interface.
+ *
+ * v1.14a Jan 6, 2001 - Minor adjustments (spinlocks, etc.)

+
+ Based on Ken Yap's Tulip Etherboot Driver and Donald Becker's
+ Linux Tulip Driver. Supports N-Way speed auto-configuration on
+ MX98715, MX98715A and MX98725. Support inexpensive PCI 10/100 cards
+ based on the Macronix MX987x5 chip, such as the SOHOware Fast
+ model SFA110A, and the LinkSYS model LNE100TX. The NetGear
+ model FA310X, based on the LC82C168 chip is supported.
+ The TRENDnet TE100-PCIA NIC which uses a genuine Intel 21143-PD
+ chipset is supported. Also, Davicom DM9102's.

+
+/*
+ 11 Apr 2001 mdc [patch to etherboot 4.7.24]
+ Major rewrite to include Linux tulip driver media detection
+ code. This driver should support a lot more cards now.
+ 16 Jul 2000 mdc 0.75b11
+ Added support for ADMtek 0985 Centaur-P, a "Comet" tulip clone
+ which is used on the LinkSYS LNE100TX v4.x cards. We already
+ support LNE100TX v2.0 cards, which use a different controller.
+ 04 Jul 2000 jam ?
+ Added test of status after receiving a packet from the card.
+ Also uncommented the tulip_disable routine. Stray packets
+ seemed to be causing problems.
+ 27 Apr 2000 njl ?
+ 29 Feb 2000 mdc 0.75b7
+ Increased reset delay to 3 seconds because Macronix cards seem to
+ need more reset time before card comes back to a usable state.
+ 26 Feb 2000 mdc 0.75b6
+ Added a 1 second delay after initializing the transmitter because
+ some cards seem to need the time or they drop the first packet
+ transmitted.
+ 23 Feb 2000 mdc 0.75b5
+ removed udelay code and used currticks() for more reliable delay
+ code in reset pause and sanity timeouts. Added function prototypes
+ and TX debugging code.
+ 21 Feb 2000 mdc patch to Etherboot 4.4.3
+ Incorporated patches from Bob Edwards and Paul Mackerras of
+ Linuxcare's OZLabs to deal with inefficiencies in tulip_transmit
+ and udelay. We now wait for packet transmission to complete
+ (or sanity timeout).
+ 04 Feb 2000 Robert.Edwards@anu.edu.au patch to Etherboot 4.4.2
+ patch to tulip.c that implements the automatic selection of the MII
+ interface on cards using the Intel/DEC 21143 reference design, in
+ particular, the TRENDnet TE100-PCIA NIC which uses a genuine Intel
+ 21143-PD chipset.
+ 11 Jan 2000 mdc 0.75b4
+ Added support for NetGear FA310TX card based on the LC82C168
+ chip. This should also support Lite-On LC82C168 boards.
+ Added simple MII support. Re-arranged code to better modularize
+ initializations.
+ 04 Dec 1999 mdc 0.75b3
+ Added preliminary support for LNE100TX PCI cards. Should work for
+ PNIC2 cards. No MII support, but single interface (RJ45) tulip
+ cards seem to not care.
+ 03 Dec 1999 mdc 0.75b2
+ Renamed from mx987x5 to tulip, merged in original tulip init code
+ from tulip.c to support other tulip compatible cards.
+ 02 Dec 1999 mdc 0.75b1
+ Released Beta MX987x5 Driver for code review and testing to netboot
+ and thinguin mailing lists.

+
+This is a tulip and clone driver for Etherboot. See the revision
+history in the tulip.c file for information on changes. This version
+of the driver incorporates changes from Bob Edwards and Paul Mackerras
+who cantributed changes to support the TRENDnet TE100-PCIA NIC which
+uses a genuine Intel 21143-PD chipset. There are also various code
+cleanups to make time-based activities more reliable.
+
+Of course you have to have all the usual Etherboot environment
+(bootp/dhcp/NFS) set up, and you need a Linux kernel with v0.91g
+(7.16.99) or later of the tulip.c driver compiled in to support some
+MX98715 based cards. That file is available at:
+
+ http://cesdis.gsfc.nasa.gov/linux/drivers/test/tulip.c
+
+NOTES
+
+I've tested this driver with a SOHOware Fast 10/100 Model SDA110A,
+a Linksys LNE100TX v2.0, and a Netgear FA310TX card, and it worked at
+both 10 and 100 mbits. Other cards based on the tulip family may work as
+well.
+
+These cards are about 20$US, are supported by Linux and now Etherboot,
+and being PCI, they auto-configure IRQ and IOADDR and auto-negotiate
+10/100 half/full duplex. It seems like a pretty good value compared to
+some of the pricier cards, and can lower the cost of building/adapting
+thin client workstations substantially while giving a considerable
+performance increase.
+
+On some PCI tulip clone chipsets (MX987x5, LC82C115, LC82C168) this driver
+lets the card choose the fastest speed it can negotiate with the peer
+device. On other cards, it chooses 10mbit half-duplex.
+
+I burned an AM27C256 (32KByte) EPROM with mx987x5.lzrom and it worked.
+According to the data sheet the MX98715A supports up to 64K (27C512)
+EPROMs,
+
+I've liberally commented the code and header files in the hope that it
+will help the next person who hacks the code or needs to support some
+tulip clone card, or wishes to add functionality.
+
+Anyway, please test this if you can on your tulip based card, and let
+me (mdc@thinguin.org) and the netboot list (netboot@baghira.han.de)
+know how things go. I also would appreciate code review by people who
+program. I'm a strong believer in "another set of eyes".
+
+Regards,
+

+ Theory of Operation
+
+I. Board Compatibility
+
+This driver is designed for the VIA 86c100A Rhine-II PCI Fast Ethernet
+controller.
+
+II. Board-specific settings
+
+Boards with this chip are functional only in a bus-master PCI slot.
+
+Many operational settings are loaded from the EEPROM to the Config word at
+offset 0x78. This driver assumes that they are correct.
+If this driver is compiled to use PCI memory space operations the EEPROM
+must be configured to enable memory ops.
+
+III. Driver operation
+
+IIIa. Ring buffers
+
+This driver uses two statically allocated fixed-size descriptor lists
+formed into rings by a branch from the final descriptor to the beginning of
+the list. The ring sizes are set at compile time by RX/TX_RING_SIZE.
+
+IIIb/c. Transmit/Receive Structure
+
+This driver attempts to use a zero-copy receive and transmit scheme.
+
+Alas, all data buffers are required to start on a 32 bit boundary, so
+the driver must often copy transmit packets into bounce buffers.
+
+The driver allocates full frame size skbuffs for the Rx ring buffers at
+open() time and passes the skb->data field to the chip as receive data
+buffers. When an incoming frame is less than RX_COPYBREAK bytes long,
+a fresh skbuff is allocated and the frame is copied to the new skbuff.
+When the incoming frame is larger, the skbuff is passed directly up the
+protocol stack. Buffers consumed this way are replaced by newly allocated
+skbuffs in the last phase of netdev_rx().
+
+The RX_COPYBREAK value is chosen to trade-off the memory wasted by
+using a full-sized skbuff for small frames vs. the copying costs of larger
+frames. New boards are typically used in generously configured machines
+and the underfilled buffers have negligible impact compared to the benefit of
+a single allocation size, so the default value of zero results in never
+copying packets. When copying is done, the cost is usually mitigated by using
+a combined copy/checksum routine. Copying also preloads the cache, which is
+most useful with small frames.
+
+Since the VIA chips are only able to transfer data to buffers on 32 bit
+boundaries, the the IP header at offset 14 in an ethernet frame isn't
+longword aligned for further processing. Copying these unaligned buffers
+has the beneficial effect of 16-byte aligning the IP header.
+
+IIId. Synchronization
+
+The driver runs as two independent, single-threaded flows of control. One
+is the send-packet routine, which enforces single-threaded use by the
+dev->tbusy flag. The other thread is the interrupt handler, which is single
+threaded by the hardware and interrupt handling software.
+
+The send packet thread has partial control over the Tx ring and 'dev->tbusy'
+flag. It sets the tbusy flag whenever it's queuing a Tx packet. If the next
+queue slot is empty, it clears the tbusy flag when finished otherwise it sets
+the 'lp->tx_full' flag.
+
+The interrupt handler has exclusive control over the Rx ring and records stats
+from the Tx ring. After reaping the stats, it marks the Tx queue entry as
+empty by incrementing the dirty_tx mark. Iff the 'lp->tx_full' flag is set, it
+clears both the tx_full and tbusy flags.
+
+IV. Notes
+
+IVb. References

+Preliminary VT86C100A manual from http://www.via.com.tw/

+http://cesdis.gsfc.nasa.gov/linux/misc/NWay.html
+
+IVc. Errata
+
+The VT86C100A manual is not reliable information.
+The chip does not handle unaligned transmit or receive buffers, resulting
+in significant performance degradation for bounce buffer copies on transmit
+and unaligned IP headers on receive.
+The chip does not pad to minimum transmit length.

+ * This is the etherboot driver for cards based on Winbond W89c840F chip.
+ *
+ * It was written from skeleton source, with Donald Becker's winbond-840.c
+ * kernel driver as a guideline. Mostly the w89c840 related definitions
+ * and the lower level routines have been cut-and-pasted into this source.
+ *
+ * Frankly speaking, about 90% of the code was obtained using cut'n'paste
+ * sequence :) while the remainder appeared while brainstorming
+ * Linux Kernel 2.4.0-testX source code. Thanks, Donald and Linus!
+ *
+ * There was a demand for using this card in a rather large
+ * remote boot environment at MSKP OVTI Lab of
+ * Moscow Institute for Physics and Technology (MIPT) -- http://www.mipt.ru/
+ * so you may count that for motivation.

+ A command-line consists of ``section''s. A section is a part of the
+ line which may be displayed on the screen, but a section is never
+ displayed with another section simultaneously.
+
+ Each section is basically 77 or less characters, but the exception
+ is the first section, which is 78 or less characters, because the
+ starting point is special. See below.
+
+ The first section contains a prompt and a command-line (or the
+ first part of a command-line when it is too long to be fit in the
+ screen). So, in the first section, the number of command-line
+ characters displayed is 78 minus the length of the prompt (or
+ less). If the command-line has more characters, `>' is put at the
+ position 78 (zero-origin), to inform the user of the hidden
+ characters.
+
+ Other sections always have `<' at the first position, since there
+ is absolutely a section before each section. If there is a section
+ after another section, this section consists of 77 characters and
+ `>' at the last position. The last section has 77 or less
+ characters and doesn't have `>'.
+
+ Each section other than the last shares some characters with the
+ previous section. This region is called ``margin''. If the cursor
+ is put at the magin which is shared by the first section and the
+ second, the first section is displayed. Otherwise, a displayed
+ section is switched to another section, only if the cursor is put
+ outside that section. */

+ Inflate deflated (PKZIP's method 8 compressed) data. The compression
+ method searches for as much of the current string of bytes (up to a
+ length of 258) in the previous 32K bytes. If it doesn't find any
+ matches (of at least length 3), it codes the next byte. Otherwise, it
+ codes the length of the matched string and its distance backwards from
+ the current position. There is a single Huffman code that codes both
+ single bytes (called "literals") and match lengths. A second Huffman
+ code codes the distance information, which follows a length code. Each
+ length or distance code actually represents a base value and a number
+ of "extra" (sometimes zero) bits to get to add to the base value. At
+ the end of each deflated block is a special end-of-block (EOB) literal/
+ length code. The decoding process is basically: get a literal/length
+ code; if EOB then done; if a literal, emit the decoded byte; if a
+ length then get the distance and emit the referred-to bytes from the
+ sliding window of previously emitted data.
+
+ There are (currently) three kinds of inflate blocks: stored, fixed, and
+ dynamic. The compressor deals with some chunk of data at a time, and
+ decides which method to use on a chunk-by-chunk basis. A chunk might
+ typically be 32K or 64K. If the chunk is uncompressible, then the
+ "stored" method is used. In this case, the bytes are simply stored as
+ is, eight bits per byte, with none of the above coding. The bytes are
+ preceded by a count, since there is no longer an EOB code.
+
+ If the data is compressible, then either the fixed or dynamic methods
+ are used. In the dynamic method, the compressed data is preceded by
+ an encoding of the literal/length and distance Huffman codes that are
+ to be used to decode this block. The representation is itself Huffman
+ coded, and so is preceded by a description of that code. These code
+ descriptions take up a little space, and so for small blocks, there is
+ a predefined set of codes, called the fixed codes. The fixed method is
+ used if the block codes up smaller that way (usually for quite small
+ chunks), otherwise the dynamic method is used. In the latter case, the
+ codes are customized to the probabilities in the current block, and so
+ can code it much better than the pre-determined fixed codes.
+
+ The Huffman codes themselves are decoded using a mutli-level table
+ lookup, in order to maximize the speed of decoding plus the speed of
+ building the decoding tables. See the comments below that precede the
+ lbits and dbits tuning parameters.
+ */
+
+
+/*
+ Notes beyond the 1.93a appnote.txt:
+
+ 1. Distance pointers never point before the beginning of the output
+ stream.
+ 2. Distance pointers can point back across blocks, up to 32k away.
+ 3. There is an implied maximum of 7 bits for the bit length table and
+ 15 bits for the actual data.
+ 4. If only one code exists, then it is encoded using one bit. (Zero
+ would be more efficient, but perhaps a little confusing.) If two
+ codes exist, they are coded using one bit each (0 and 1).
+ 5. There is no way of sending zero distance codes--a dummy must be
+ sent if there are none. (History: a pre 2.0 version of PKZIP would
+ store blocks with no distance codes, but this was discovered to be
+ too harsh a criterion.) Valid only for 1.93a. 2.04c does allow
+ zero distance codes, which is sent as one code of zero bits in
+ length.
+ 6. There are up to 286 literal/length codes. Code 256 represents the
+ end-of-block. Note however that the static length tree defines
+ 288 codes just to fill out the Huffman codes. Codes 286 and 287
+ cannot be used though, since there is no length base or extra bits
+ defined for them. Similarly, there are up to 30 distance codes.
+ However, static trees define 32 codes (all 5 bits) to fill out the
+ Huffman codes, but the last two had better not show up in the data.
+ 7. Unzip can check dynamic Huffman blocks for complete code sets.
+ The exception is that a single code would not be complete (see #4).
+ 8. The five bits following the block type is really the number of
+ literal codes sent minus 257.
+ 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
+ (1+6+6). Therefore, to output three times the length, you output
+ three codes (1+1+1), whereas to output four times the same length,
+ you only need two codes (1+3). Hmm.
+ 10. In the tree reconstruction algorithm, Code = Code + Increment
+ only if BitLength(i) is not zero. (Pretty obvious.)
+ 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19)
+ 12. Note: length code 284 can represent 227-258, but length code 285
+ really is 258. The last length deserves its own, short code
+ since it gets used a lot in very redundant files. The length
+ 258 is special since 258 - 3 (the min match length) is 255.
+ 13. The literal/length and distance code bit lengths are read as a
+ single stream of lengths. It is possible (and advantageous) for
+ a repeat code (16, 17, or 18) to go across the boundary between
+ the two sets of lengths.

+ Huffman code decoding is performed using a multi-level table lookup.
+ The fastest way to decode is to simply build a lookup table whose
+ size is determined by the longest code. However, the time it takes
+ to build this table can also be a factor if the data being decoded
+ is not very long. The most common codes are necessarily the
+ shortest codes, so those codes dominate the decoding time, and hence
+ the speed. The idea is you can have a shorter table that decodes the
+ shorter, more probable codes, and then point to subsidiary tables for
+ the longer codes. The time it costs to decode the longer codes is
+ then traded against the time it takes to make longer tables.
+
+ This results of this trade are in the variables lbits and dbits
+ below. lbits is the number of bits the first level table for literal/
+ length codes can decode in one step, and dbits is the same thing for
+ the distance codes. Subsequent tables are also less than or equal to
+ those sizes. These values may be adjusted either when all of the
+ codes are shorter than that, in which case the longest code length in
+ bits is used, or when the shortest code is *longer* than the requested
+ table size, in which case the length of the shortest code in bits is
+ used.
+
+ There are two different values for the two tables, since they code a
+ different number of possibilities each. The literal/length table
+ codes 286 possible values, or in a flat code, a little over eight
+ bits. The distance table codes 30 possible values, or a little less
+ than five bits, flat. The optimum values for speed end up being
+ about one bit more than those, so lbits is 8+1 and dbits is 5+1.
+ The optimum values may differ though from machine to machine, and
+ possibly even between compilers. Your mileage may vary.

+ routine that uses these macros from a global bit buffer and count.
+
+ If we assume that EOB will be the longest code, then we will never
+ ask for bits with NEEDBITS that are beyond the end of the stream.
+ So, NEEDBITS should not read any more bytes than are needed to

+
+ However, this assumption is not true for fixed blocks--the EOB code
+ is 7 bits, but the other literal/length codes can be 8 or 9 bits.

+ * char *
+ * tparm(string, ...)
+ *
+ * Substitute the given parameters into the given string by the following
+ * rules (taken from terminfo(5)):
+ *
+ * Cursor addressing and other strings requiring parame-
+ * ters in the terminal are described by a parameterized string
+ * capability, with like escapes %x in it. For example, to
+ * address the cursor, the cup capability is given, using two
+ * parameters: the row and column to address to. (Rows and
+ * columns are numbered from zero and refer to the physical
+ * screen visible to the user, not to any unseen memory.) If
+ * the terminal has memory relative cursor addressing, that can
+ * be indicated by
+ *
+ * The parameter mechanism uses a stack and special %
+ * codes to manipulate it. Typically a sequence will push one
+ * of the parameters onto the stack and then print it in some
+ * format. Often more complex operations are necessary.
+ *
+ * The % encodings have the following meanings:
+ *
+ * %% outputs `%'
+ * %c print pop() like %c in printf()
+ * %s print pop() like %s in printf()
+ * %[[:]flags][width[.precision]][doxXs]
+ * as in printf, flags are [-+#] and space
+ * The ':' is used to avoid making %+ or %-
+ * patterns (see below).
+ *
+ * %p[1-9] push ith parm
+ * %P[a-z] set dynamic variable [a-z] to pop()
+ * %g[a-z] get dynamic variable [a-z] and push it
+ * %P[A-Z] set static variable [A-Z] to pop()
+ * %g[A-Z] get static variable [A-Z] and push it
+ * %l push strlen(pop)
+ * %'c' push char constant c
+ * %{nn} push integer constant nn
+ *
+ * %+ %- %* %/ %m
+ * arithmetic (%m is mod): push(pop() op pop())
+ * %& %| %^ bit operations: push(pop() op pop())
+ * %= %> %< logical operations: push(pop() op pop())
+ * %A %O logical and & or operations for conditionals
+ * %! %~ unary operations push(op pop())
+ * %i add 1 to first two parms (for ANSI terminals)
+ *
+ * %? expr %t thenpart %e elsepart %;
+ * if-then-else, %e elsepart is optional.
+ * else-if's are possible ala Algol 68:
+ * %? c1 %t b1 %e c2 %t b2 %e c3 %t b3 %e c4 %t b4 %e b5 %;
+ *
+ * For those of the above operators which are binary and not commutative,
+ * the stack works in the usual way, with
+ * %gx %gy %m
+ * resulting in x mod y, not the reverse.

+If you have created an image aimed to a floppy, then something like:
+
+dd if=<type>.image of=/dev/fd0[u<size>] bs=512
+
+will be more than enough... if you have formated the floppy correctly
+using \`superformat' to be found in \`fdutils' package.
+
+For El Torito floppy emulation :
+
+mkisofs -b <image> -c boot.catalog -o raw.iso <dir>
+
+And for El Torito Hard Disk emulation:
+
+mkisofs -b <image> -hard-disk-boot -c boot.catalog -o raw.iso <dir>

+Enjoy!
