If you have the Xylogics 472 tape controller and the Sun Multibus
to VMEBUS adapter on a Sun workstation, please send me the switch
settings for these boards. We have installed them here
and set the switches according to our interpretation of the manuals.
The boards work just fine for small files but have occasional
problems writing large tars and dumps.
Sometimes an interrupt is lost and the tar or dump
fails in the middle.
Therefore, I would like the switch settings to verify
that our set-up is correct.
Any other advice you could offer will be greatly appreciated.
We are using the Fujitsu 2444AC tape drive.
Thanks very much in advance,
Jon Hull

=====================================
P.S. This is the tape controller and adapter Sun sells
for their 1600/6250 bpi tape system.
I called the local Sun people but they
wouldn't assist me because I didn't purchase
the controller and drive from them.
