Alex, you may want to look at the Ethernet howto. I mention this because
it talks about how Linux can sometimes guess the wrong IRQ with older ISA
cards like yours. This card, if it is indeed from 1992 as you state
predates ISA Plug 'N Play, so that won't help. Does it have jumpers? If
you can, see what IRQ and base address are given the card on a known
working machine. Then, look at /proc/interrupts and /proc/ioports on your
Linux machine with the card installed and see if they match. although I
thought the card was working before, I am beginning to wonder if it's some
kind of resource conflict. As examples, here are my /proc/interrupts and
/proc/ioports. Note that my /proc/interrupts looks a bit strange because
I'm utilizing the APIC on my machine which gives me interrupts above 15.
Wish Windows knew about this.
