| **flashrom** is a utility for identifying, reading, writing, verifying and erasing flash |
| chips. It is designed to flash BIOS/EFI/coreboot/firmware/optionROM images on mainboards, |
| network/graphics/storage controller cards, and various other programmer devices. |
| |
| * Supports more than 627 flash chips, 407 chipsets, 539 mainboards, 94 PCI devices, |
| 30 USB devices and various parallel/serial port-based programmers. |
| For more information, see the pages under :doc:`/supported_hw/index`. |
| |
| * Supports parallel, LPC, FWH and SPI flash interfaces and various chip packages (DIP32, |
| PLCC32, DIP8, SO8/SOIC8, TSOP32, TSOP40, TSOP48, BGA and more). |
| |
| * No physical access needed, root access is sufficient (not needed for some programmers). |
| |
| * No bootable floppy disk, bootable CD-ROM or other media needed. |
| |
| * No keyboard or monitor needed. Simply reflash remotely via SSH. |
| |
| * No instant reboot needed. Reflash your chip in a running system, verify it, be happy. |
| The new firmware will be present next time you boot. |
| |
| * Crossflashing and hotflashing is possible as long as the flash chips are electrically |
| and logically compatible (same protocol). Great for recovery. |
| |
| * Scriptability. Reflash a whole pool of identical machines at the same time from the |
| command line. It is recommended to check flashrom output and error codes. |
| |
| * Speed. flashrom is often much faster than most vendor flash tools. |
| |
| * Portability. Supports DOS, Linux, FreeBSD (including Debian/kFreeBSD), NetBSD, OpenBSD, |
| DragonFlyBSD, anything Solaris-like, Mac OS X, and other Unix-like OSes as well as GNU Hurd. |
| Partial Windows support is available (no internal programmer support at the moment, hence |
| no "BIOS flashing"). |
