[luau] Help with lan drivers for nvidia and 3com

[Alvin Murphy]

Hi:  My son got a "killer" box for his birthday with a fast AMD 
processor and a board with two onboard lan "cards";  I have my own 
drive, so I installed Mdk 9, which is fine, but I cannot find drivers 
for either card. Cany anyone help.  WinXp identifies one as Nvidia 
nForce MCP, the other as 3com 3c902b-EMB integrated fast ic controller. 
Appreicate any help finding driver(s).
