I'm trying to set up a SuSE 5.3 linux box with two ethernet cards - one a 3com pci card (runs on the 3c59 modules), and the other a 3com isa 3c509B (supposedly runs on the 3c509 module). The pci card works fine on eth0 with the 3c590 module, and that card connects my compter to the net. I want to connect the 3c509 card to another the card on another computer and then use masquerading to give the second computer access to the internet. Unfortunately, I can't get the 3c509 module to recognize the isa card on eth1. When I do a modprobe 3c509, or an insmod 3c509, all I get is this message: 3c509.o: init_module: Device or resource busy I've tried setting irq=10. That doesn't help. What else should I be trying? How do I find out what "device or resource" might be "busy?" I have disabled PnP on the card (via a dos program provided by 3com), and I know that the card works fine in the isa slot of another computer. So the card itself is unlikely to be the problem? So what else do I need to do? Is there some obscure incompatibility between my two cards? Are they fighting for the same base address, or what? Thanks.
