Set the port to the correct place (0x250 i think) and whatever other setable parameters you can do from the hardware (just memory address if I remember correctly, I haven't done this since august). BSD will setup the card for the correct IRQ. Note that to use the AUI port on the card you need to get the patched ifconfig that lets you tell the 3c503 to do this or hack the if_ef.c driver (which is what I opted to do, since the new ifconfig wasn't around in august). alex
