I'm only familiar with LILO and software RAID, so this may or may not be appropriate. Once I have my lilo.conf file set up, I usually run it on several different locations. I'm talking about: lilo -b /dev/md0 lilo -b /dev/hda lilo -b /dev/hdc I think the behavior of LILO differs by version. On more recent ones I've seen it actually expand md0 and write the boot sector of both hda and hdc, but who knows what RH7.2 has by default. The -b tells LILO where to write the boot sector, so this forces it to be put on the boot sector of both physical drives. I actually don't think writing direcly to /dev/md0's bootsector does anything particularly useful, since I think it'd be stored in the superblock or something similar (and therefore not what the BIOS is looking for), except for the behavior on certain LILO versions as I mentioned above.
