http://ubuntuforums.org – I have an Asrock A330GC, with onboard ethernet, and an Engenius PCI card for wifi. I installed ubuntu server 9.10 no problems, and it picked up my ethernet in the installation with no difficulties. I couldn't get 9.10 to do what i wanted, so I tried installing 8.4 instead. This however didn't pick up any of the drivers, so i couldn't get online. (HowTos)
