1) PnP cards often come with a config utility so you can manually
configure them. Drop it in a PC and run the utility to turn off PnP and
config the settings you want. Then put it in your project and go.
Stores like Fry's sell NE2000 cards like this for ~$10.

2) Skip the ISA card slot and use these proto cards for PIC and AVR:

Fred has NE2000, Crystal, and ASIX (NE2000 w/ 10/100) boards - plus
driver code. He's also written a book on the subject, and an article in
the Oct 2002 CircuitCellar (AVR+ASIX). And... he'll sell you the chips
and magnetics for a decent price if you roll your own boards.

3) Here's a newer solution that's turnkey; however, they're pricey (~$50
ea.) and limited in their back-end connectivity. If you just want to
put an Internet face on your widget, these are a good fit. If you want
to do something high-performance, they're not.
