Hi Johnny,
Just getting back to the VAX, so here is what I did and am thinking.
I have a KFQSA installed in my VAXServer 4000-200 and configured for 2
disks.
set host/uqssp/maint/serv 0
? set 0 772150 21
? set 1 760334 21
? set 6 KFQSA
I was going to run a DSSI cable from the left bulkhead connector on my
VAX chassis to the front of the KFQSA's board connector.
This I hope will allow me to jumper my internal chassis DSSI bus with my
2 hard drives, to the KFQSA.
Seeing that the KFQSA is supported in NetBSD and the controller on the
KA660's SHAC is currently not, I was hoping to boot via the KFQSA.
I see that my KA660's SHAC is set to id 7 and that is why I chose id 6
for the KFQSA.
Does this sound about right?
Thanks,
James

Not sure what jumpers you are thinking about, but yes, the KFQSA is
just
a normal MSCP controller from the computer point of view. So it works
(but see below).

Not sure what you are talking about here. The KFQSA sits on the Qbus,
and connects to DSSI disks. If you plan to connect both DSSI
controllers
to the disks, then yes, one should be unit 6 and the other 7.

Obviously all up to you... :-)

That would also be nice. I have had a long term plan to get the
whole CI
code from Ultrix ported over to NetBSD. Obviously this might not be
possible to distribute as is, since it's copyrighted. But it would be a
start. However, I have been too busy with other things, and meanwhile
NetBSD have deteriorated some.
Anyway, I happen to have a KFQSA, and last I tested it with NetBSD, it
ran for a while, but NetBSD got stuck after some time. I think there
are
some bugs somewhere that either plays badly with the KFQSA, or else are
buggy in some other way (having two UDA-50 on two separate Unibuses on
an 8650 also do not work).
So there is some chance that you will not find things very usable in
the
end anyway, even with the KFQSA.
Johnny
