Your problem is almost certainly that the MacOS driver for the card does not 
disable it when A/UX is booted, and your A/UX system is hit by interrupts it 
cannot handle. Use the Chooser under MacOS to select network "Built-in" and 
try again. Once you have a correctly configured A/UX kernel including a driver 
for your card then you *might* get away with re-enabling the board for use 
under MacOS.

The intended interface was probably known to Kinetics but since Apple didn't 
yet use it, Kinetics didn't ship it. Kinetics was swallowed up by Novell, the 
rights to the boards were sold elsewhere (Dayna Systems?) and generally all 
support for existing boards vanished. The only thing where Apple is at fault 
is that nobody seemed to know that A/UX needs to have the boards physically 
disabled until the A/UX drivers are ready to go. I did get Mac DTS to agree 
that this is a suitable subject for a TechNote and one should eventually 
appear.
