Thanks for all of your hard work! I have everything up and running, sleep and sound have no problems at all. Unfortunately I was unlucky enough to get a G31M-E2SL 2.0 board from NewEgg for this project, so I also had to install an Encore ENGLA-1320 card (RealTek 8169). It worked out of the box under 10.5.6, with the vanilla IONetworkingFamily kext. In 10.6 it's not detecting any PCI card as installed. It shows up in the POST and it has a light, so I know it's working, I just can't get show up. Any ideas?
