Latitude C800

I loaded Windows XP Pro on a Latitude C800. I am trying to find a driver for the NIC but am having no luck. In Device Manager the NIC reads as a 1394 Net Adapter. I downloaded the Windows 2000 driver for the NIC and the system says The wizard it could not find a better match for your hardware than the software you currently have installed. Where can I find device drivers for a Latitude C800 with Windows XP
