Hmm.. I've got a manual for the Viking UDT, and I'll try to remember to
bring it in on Monday.
I don't know anything about how 2.11BSD boots. However, I had an
time trying to get 4.3BSD on my 750 to boot off this controller. It
that the Viking's emulation of the UDA50 isn't *quite* accurate, and
that the 4.3 boot
code was using one of the edge-of-the-envelope features that the Viking
emulate right. I modified the bootstrap slightly and got it going.
has anything to do with your problem, I don't know. (It was worth all
in the end, to see the monster hulking 750 booting of a little dinky
plastic zip drive!)
