xfx nForce 750a SLI ethernet driver

Chris had to wipe his hard drive and reinstall everything. For some reason it keeps asking for the ethernet driver and it doesn't seem to be installing for him from the XFX nForce 750a SLI Motherboard installation CD. Thus he can't get on the internet. I can't seem to put the right words in, to get a driver for him. I get everything but the ethernet driver. Can someone help? Where do I go?

Can't figure out why it won't install from the motherboard installation cd. It has done so several previous times.
