        fdisk needs to be run and the 4 HD partitions marked as 0x8e -- Linux LVM

        - If this is run on a 2.4 kernel system then LVM must be configured and the kernel rebuilt. In a 2.5 environment
        you must configure Device Mapper and install LVM2 from www.systina.com for the testcase to run correctly.

        - These operations are destructive so do NOT point the tests to partitions where the data shouldn't be overwritten.
        Once these tests are started all data in the partitions you point to will be destroyed.
