This is somewhat shot-in-the-dark, but in your SCSI BIOS settings, are
both of those two drives marked as bootable, and/or are the partitions
for both (via fdisk) marked as so? 0x80 would seem to indicate that
the scsi adapter is not making a bootable main drive available (afaict)
so I'd check these settings...
If the two drives are indeed identical, what happens if you swap their
scsi id's? (most scsi bios assigns settings based on scsi id of the
device)
just in case it helps, what was the output from lilo -v?

IMHO, b/c the second disk isn't marked to be bootable, although I haven't
checked first-hand to make sure the MBR gets mirrored (although I'm 99%
sure that it is :)
