	I don't actually have a dual-SCSI controller in my 3100, but if
memory serves. The A channel was looped for the internal drives, and the
B-channel was for external devices only and wasn't looped. That could just
be totally off the wall, but who knows. Methinks there was some docs
on the dual channel controller on vaxarchieve or the NetBSD web site
(main page => Documentation => Hardware Documentation)
	I've seen very very strange things when you don't use a looped
cable on a looped controller (Like the same drive appearing on all
seven SCSI ID's at the same time) Just remember, if you think SCSI is bad,
try IDE or ST-506 :-)
