SCSI Strangeness

[jd-wong@uxa.cso.uiuc.edu (Jim Wong)]

I'm experiencing some bizarre SCSI behavior with my GS; I have an
Apple High Speed SCSI card, a 20 MB Seagate drive, and a 105 MB
Quantum disk.  The Seagate is the last device in the SCSI chain and is
internally terminated.  When I boot from the smaller drive, everything
seems to work perfectly.  On the other hand, when I switch the drives'
SCSI id's to boot GS/OS from the Quantum, my machine crashes at
seemingly random points during the boot process, sometimes dumping me
into the monitor, sometimes simply hanging, and sometimes generating
error messages like "Unable to load TS 2..." or "...Apple Disk 3.5
requires a driver..."; if I press the space bar to see what's being
loaded, it occasionally dumps inverse characters all over the screen as
the system heads south.  Booting ProDOS 8 by holding down the pressing
the "8" key seems to work, however.  Can anyone explain this odd
behavior?
