Hi Mike,
I tried your suggestion below, and for some reason its still assigning the
same interrupt (whichever one I pick) to both the network card and the
wavelan card, and interstingly enough even if I remove one of them, its
still trying to get a routeable interrupt and the wavelan still doesnt
work. Any way that I can get this thing to give me a straight interrupt
on all cards without trying to do funny irq routing?
Thanks
Andrew
