you do not want to use this. What it is for is when you can select
booting from SCSI drives in your BIOS. It lets LILO know that your SCSI
drives are the first two hard drives in the BIOS numbering. LILO has no
way to tell how your BIOS numbers the drives, so it defaults to IDE drives
first, and then SCSI drives.
>From the sound of things, your BIOS does not support booting from SCSI
drives, but your SCSI controler card has its own BIOS that will override
your BIOS. (I am guessing here!) If this is the case, you can go two
different routes. The simplest way is to boot from a boot disk and
reconfigure LILO to install on the MBR on the IDE drive. (boot=/dev/hda)
You may also be able to get away with adding:
disk=/dev/sda
bios=0x81
This tells LILO that your first SCSI drive is the second drive the BIOS
sees. The problem with this is that if you add another IDE drive, or
remove the IDE drive, it breaks LILO!
Also, depending on your SCSI bios, I am not sure what will happen when the
IDE drive is formatted, and has a valid primary partation that is marked
active. Your system may then try and boot from the IDE drive. I would
love to play with the system to see what would happen, but it is probably
more expermenting then you want to do...
