Right, so IRQ 9 is really correct.  My understanding is that on all AT class
machines, IRQ 2 and IRQ 9 are really the same.  Do you even have an AUI port
on this card?  If there is only one interface, then the "aui" message is
really a red herring.

It generally means that something is screwed up ... one common thing is
something interfering with the shared memory window.

If your card won't work under DOS with the supplied software, it's unlikely
to work under NetBSD :-)  You might try playing with your BIOS - some BIOSes
re-map these shared memory regions, but allow you to turn off the mapping.

It's either that, or install off of floppies (blah).

No, ignore it - it's a failed probe from another ethernet card driver.
