I had a similar problem in trying to boot from SCSI with IDE drives
present. My motherboard did not like to boot from SCSI even though I
told the SCSI controllers that they were supposed to handle booting
(tried using the adaptec AND some buslogic, but the motherboard always
took over).
I ended up adding the following to my /etc/lilo.conf
-- begin part of lilo.conf --
# Overrides the default mapping between harddisk names and the BIOS'
# harddisk order. Use with caution.
disk=/dev/hda
bios=0x81
disk=/dev/hdb
bios=0x82
disk=/dev/sda
bios=0x80
# Specifies the boot device. This is where Lilo installs its boot
# block. It can be either a partition, or the raw device, in which
# case it installs in the MBR, and will overwrite the current MBR.
#
boot=/dev/sda
# Specifies the device that should be mounted as root. (`/')
#
root=/dev/sda3
--end selected portion of lilo.conf--
I looked for some time to find help on this and finally reread the man
page along with some info I found online (can't remember where) and came
up with this solution. It was the only way I could get the system to
boot to the SCSI drive, I believe because the motherboard was being
grumpy.
I know that if I add new IDE drives (which is likely to happen since
I've just filled the 40G RAID1 I have) I will have to edit my lilo.conf
to recognize the drives differently. I cannot add IDE drives without
editing lilo.conf - well, at least not to get it to boot, I think.
Standard 'it works for me but lilo can screw up everything on you'
warning applies right here - don't blame me. I'd suggest googling for
'bios=0x80' and you're likely to find a bunch of helpful information.
Hope this helps you.
