If your motherboard wasn't supported by Windows Vista, it won't be supported by 7. NForce 2 is 6 years old, old enough that it didn't even support dual core processors. It's not likely you'll get it to work unless a 3rd party fix is provided, and that'll only happen after the full release. I'd say either grab a cheap NIC from your local computer store, or you're SOL for now. Sorry, Mate.
