Here's the odd part: With the original
Apple-branded OEM Quantum drive
(which I do not want to overwrite) on the SCSI bus the installer
recognizes the CD-ROM and is willing to begin the process. However, with
any of the third-party hard drives in the system it is unable to
recognize _anything_ on the SCSI bus - doesn't see the hard disk or the
CD-ROM. I've checked and double-checked the jumpering on the hard disk
and it's not conflicting with the CD-ROM. Both the IBM and Fujitsu are
fairly run-of-the-mill 50-pin SCSI units.
Did you only check the SCSI ID jumpers, or did you also check the
termination and termination power jumpers? Multiple devices providing
terminator power can sometimes cause this symptom, especially if the
SCSI bus arbiter is a bit sensitive.
