Thanks for the tip lagagnon, I followed your instructions (I had to edit /etc/isapnp.conf to uncomment some stuff) and it looks like a 3com module is being loaded now. However, I think it's the wrong module: 3c59x. I believe it should be using the 3c515 module since that's my NIC model. BTW, when I ran netconfig previously, it would try to detect card and it would detect the same module:
A network card using the 3c59x.o module has been detected.
I can't seem to get the network to work though with that module. Are there additional steps I need to take to get the network to come up after that module is loaded?
Why is it detecting the wrong module and how can I correct it? Thanks for any tips!
