Maybe later I'll try it again...right now I'm looking for a good way to
quickly copy files from disk to disk...  pax seems to interfere a lot with
file modes, etc trying rsync now but maybe I have to go back to tar!

FWIW, I had a lot of trouble getting termination "right" - I've internal
8bit, external 8bit and internal 16bit SCSI devices (which I'm not sure is
actually supported...).  But anyway, NT installed ok, as did BSDi (but both
onto the 2GB disk - BSDi 4.0 doesn't seem to know about targets > 7 on their
boot diskette...sigh).
