Everything works fine, with the exception of the onboard ethernet, which is a Realtek RTL8105E chip. The stock CentOS installation attempts to use the r8169 driver, which does not work. I've been around the block a few times dealing with Realtek interfaces and their driver hell, but this one is stumping me.

But, I just cannot get any traffic to pass. There is a link light for the ethernet interface, but no actual activity when testing.

Hi Tim.
If this NIC is built onto the motherboard, would it not be
easier just to find an (PCI?) expansion slot NIC that is
known to work out of the box on Centos 5.5 and use that
instead?
