Allen,

i'm very sorry, but only now, after you taught mme how to relate the dm
and sb commands in Macsbug to the Nubus slots where you are talking to,
I realised, using "dm feed0000" etc. I'd have always spoken to the
wrong one. (I had changed the slots after your advice to test, if there
might be a broken Nubus slot). I'm inconsolable, but please consider,
I'm really not that hardware expert :))

Anyway, the Asante MacCon is in slot D on the IIci and here come all
infos I got about:

1) Info from "Slots" (program):

2) What Asante Troubleshooter says:

 Ram test failed at fddd0000H, expect:  0H, actual:  60H
 NIC Arbitration Failed
 NIC Transmission Failed. Transmit collided.


3) Macsbug:

Allen, please note in 1) (Slots) Asante Techn., Inc is abbreviated by
myself. Really it is Asante Technologies, Inc. And in 3 b), at the
first displaying line there is indeed missing the final * (it's one
character less than all other displaying lines).

Now, I hope, you might be able to deduct something from this.

Sorry again and TIA,

Ulrich
