Let me see if I understand this correctly. You get the normal LILO:
prompt, and you can boot DOS and Windows from lilo, right? But when you
pick booting Solaris, you get L? as the start of another LILO: prompt?
If this is what is happening, did you install another copy of LILO to
the MBR of the SCSI drive to load Solaris?
What I think may be happening is that the loader on the SCSI drive
thinks that it should be BIOS drive 0x80 because it was the first drive
the BIOS saw at the time Solaris was installed. So it is trying to load
the rest of the loader from the wrong drive. If this is what is going
on, you can probably fix it by doing as Forrest Taylor, sugested, and
modifing your Solaris entry to:
other=/dev/sdc
label=Solaris
map-drive = 0x82
to drive = 0x80
Another way to fix it would be if you can boot Solaris with a floppy,
and then re-install the boot loader so that has the correct BIOS drive.
That way, you will not need the drive re-mapping, and you will not run
into problems if you later update the Solaris boot loader. The
disadvantage is that if you remove the RAID aray at a later time, you
will not be able to boot off the SCSI drive, because the loader will
again be trying to load from the wrong drive.
