Ok, Here is my synopsis on this, I will be a bit more thorough than I
was yesterday and it should cut down on a lot of the "What the
*uck??!!!'s" that I voiced during this for someone attempting the same
thing.......
1. The hardware that I have is, 2 existing ide drives on my motherboards
primary ide controller, being hda and hdb. hda has my existing linux
install and hdb has my existing xp install.
2. I installed a new scsi drive with a separate controller (not on
motherboard), being sda
3. I installed RedHat 8 on the new scsi drive and the problem arose when
lilo did not install correctly, i noticed this on the first boot after
installing RedHat. This situation can be confused by the fact that you
can tell BIOS to boot from different devices first. I wanted it to boot
the scsi drive first and I wanted lilo installed on that drive and to
then dual or triple boot from there.
4. When I rescue booted the system and then tried to config lilo
manually and run, it kept giving me errors that lilo was not installed
on the first drive.
5. So the system thinks that the ide drives are first and the scsi after
no matter how the system booted and which drives the system booted from.
I don't believe this is just a Linux thing but so it goes.
6. I then read the man page on lilo.conf and found that you can tell
lilo that the scsi drive is first with the line "disk=/dev/sda
bios=0x80". It seems lilo translates by default, first drive (hda=0x80)
second drive (hdb=0x81), etc. I then ran lilo and got no errors and the
system booted just fine. NOTE: I still have the bios booting from scsi
first.
7. Still had a problem though, could not dual boot to my xp drive. After
a lot of trial and error, the following additions to lilo.conf made it
work, "disk=/dev/hdb bios=0x83" and the following
other=/dev/hdb1
label=Windows
table=/dev/hdb
map-drive=0x80
to=0x83
map-drive=0x83
to=0x80
The tricky part here, is that because I told it that the scsi is 0x80,
the other drives bumped down respectively, i.e. how the hdb drive became
0x83 instead of 0x82.
8. After those changes, both boot perfectly, from lilo installed on the
scsi drive.
Hope this keeps the "What the *uck???!!!'s" down, lol.......
