thanks for your report! Do you know which revision your board is? There are two: 1.0 and 1.1 http://www.gigabyte.com/products/product-page.aspx?pid=3D4288 http://www.gigabyte.com/products/product-page.aspx?pid=3D4766
I have 1.0. Sorry I forgot to mention that.
Did that work out eventually?
Yes, that layout file restored the MAC address and generlly got things working. Apologies again for not making that clear.
Thanks for flashrom!
