Archive VP402 card crashes system

[John F. Haugh II]

i just installed an archive vp402 qic-02 tape drive controller
card and have found this wonderful problem.  i am running sco
xenix 2.2.3.  certain tape commands are supposed to work without
waiting for the current tape operation to complete.  however,
this doesn't always happen and the tape command hangs up.  when
this happens often the system will magically reboot itself as
soon as the current tape operation completes.

please reply to my address as i don't generally frequent this
newsgroup.
