I have another question about that motherboard. I have the same motherboard and processor that you have. There are two Marvell drive controllers on that motherboard in addition to an Intel Series 7 C216 controller.
Which controller(s) did you connect your SATA drives to? Also, did you need to add any OEM.tgz files into a custom ISO as you did with the Intel NIC driver? I follwoed the custom ISO steps you pointed us to. When I boot up, I get past the missing NIC error now thanks to the custom ISO. But now I get a no drives found message when it comes time to install.
Also, to answer your question, I have found NO information regarding a driver for the second NIC on these boards, which is the Atheros 8151 model.
Thanks
