As a test case, have you tried booting from a recent 
Live CD version of Linux, like Parted Magic:

It's also included on the UBCD:

If you can get this onboard NIC working OK from Parted 
Magic, then at least you know it's not the NIC hardware.

You might find the hardware identification routines in the 
Parted Magic distro can give you some helpful pointers too.
