I have debian installation on a asus nforce2 motherboard with two scsi disks (on a adaptec 29160N) and one
IDE hd.
rainman:/proc# more /proc/scsi/scsi

i installed a small system on the ide hd, and afterwards partitioned both scsi disks like this:

i installed the LILO in the mbr of /dev/sda
rainman:~# more /mnt/root/etc/lilo.conf
lba32
disk=/dev/md1
bios=0x80
partition=/dev/md0
boot=/dev/sda
root=/dev/md1
...
mobo BIOS boot order is SCSI, scsi-bios boot device is 0 (/dev/sda) but it still hangs on 'LI'
i had that problem too with a non raid install on the scsi disk, but adding a 'bios=0x80' helped that work
out, but now it still does not boot from the scsi, and i dont feel like putting the MBR on the ide disk,
would be nicer to have it on the scsi disks. anyone has an ide or need information ?
thanks in advance
bruno
