Hmmm, that "warning: BIOS drive 0x81 may not be accessible" sounds like a
killer message rather than informational.  0x81 is the second drive in the
drive table of the planar BIOS.  That sounds like it would be your SCSI 
drive.  Is your CMOS set up correctly?  Is there a driver for the SCSI drive
loaded at the time that LILO executes?  Remember that LILO runs under 
drivers that were loaded as part of the planar BIOS since it must execute
before Linux is even a wet dream.  Whatever is causing THIS message sounds
like it is a major part of your real problem.  Your system sounds like is is
not THAT much different from mine that you should see subtantively different
things than I see, and the message about not being on the first disk is 
explainable (BIOS disk 0x80 is the first fixed disk and will be an ATA drive
if one is present.), while the other message is not explainable in a 
properly configured system.
