I have an Asus P5B-E with, what I believe, to be a Realtek RTL8111/8168B on board NIC.

When I try to activate the NIC via NetConfig it indicates that "rtl8129 device eth0 does not seem to be present, delaying initialization." During config I defined eth0 with both at different times the rtl8129 and 8111/8168B drivers but get the same results for both.

I'm running RH6, Kernel 2.6.18-1.2798.

I'm stuck. Help a noob?
Thanks in advance.
