Could you find your solution?
I have the same problem but with other board. Please tell me if you found how to resolve this.
Knowing which board is kind of important or at least which NICs are on the board, however if its an Intel NIC you will likly find the driver at this link.
(this file is HUGE)
Please excuse my ignorance. The NIC you are talking about, is that one wich appears on the ethernet board tag?, in my board it says NIC, then a barcode then 129011342C03801.
