Try to identify the make and model of the NIC, if that info is printed on the card, you may be able to find suitable drivers online (search via a search engine).

Failing that, I'd suggest you get a name-brand NIC (e.g. Intel, Netgear, 3Com) which has good driver support and use that instead.

The current cost of network cards is so small it really isn't worth spending the time to try and track down hard to find drivers unless it is immediately obvious from looking at the card. New D-Link cards retail at about £7-8 ($15) and come with a driver CD to get straight on with the task in hand.
