HELP! - LILO (SCSI)

[Andrew McRobert <mcrobert@central.murdoch.edu.au>]

hi all

I tried adding a ULTRA SCSI hard disk to the server (on the separate ULTRA
SCSI channel on the controller), and while the system correctly identifies
all of the attached SCSI devices (including the two other HDDs), it gives
me this message when I connect the ULTRA SCSI drive:

can't locate boot device

If I disconnect it, ie. take my system back to exactly the way it was
before, LILO stops at "LI"???!?!?!?

Does anybody have any idea why this is happening??

thanks a lot
Andrew
