I can't find that specific board on Intel's site. Do you happen to know what chipset the NIC is based on (not the mother board, but the actual Network Interface Card)? It should be something like 82555, 82559, etc... something like that. For any of the 8255x cards the eepro100 driver should be correct. If it's based on a different chipset then you may need a different driver.
First step is to read the motherboard manual and determine what chipset the NIC is based on.
