But the card may not work if the IRQ from the pccard.conf doesn't match the one in the CIS. The FreeBSD pccardd doesn't do anything with the CIS IRQ list in any case. > > > This *works*.

If I try to use the first free irq for my ethernet card it doesn't work (I can't remember which one it is, but it is free). However, if it's one of the 'accepted' IRQ's, it does work. I have no good explanation of why this is the way it is, other than what I stated already. Nate
