Ethernet PCMCIA Card Driver?

Hello Ppl.

I was wondering if someone would be kind enuff to give me some assistance. Ive just started a new job, and have been given a Ethernet PCMCIA Card, that is the credit card type suitable for a laptop. Unfortunetly, There is no distinguishable brand name. The only writing is Ethernet PCMCIA card, and FCC numbers. The FCC number i believ might help is: 146855-000, or 146136-002.
Ive looked at alot of driver sites, to no avail.
IN NT it detects as a Ethernet PCMCIA Ethernet PCMCIA card, thou this doesnt help as im after windows 2000 drivers!
Anyone able to help me, based off this information? ITs all i have, apart from a barcode.
