SCSI bus topology questions

--> To add to the confusion, both the Award and Adaptec BIOSes have
--> termination settings.  The Award BIOS two on/off termination settings,
--> one for high, one for low.  The Adaptec BIOS has only one one/off
--> setting, simply labeled "termination".

Hmmm .. my Award BIOS has these two:

	ONB SCSI SE Term.
	ONB SCSI LVD Term.

I disabled the first one, since I have devices on both the 50-pin
and the 68-pin SE segments.  I left the second enabled, since the
motherboard is one end of the LVD segment.

I also disabled the "Host Adapter Termination" in the Adaptec BIOS.

With those items disabled, my system boots fine and has no trouble
accessing devices on all three SCSI bus segments.

Thanks for the suggestions.
