I have installed retail once before on this board, worked fine until 10.5.8. It eliminated my NIC card, so I backed up my files and did a reload to bring it back to 10.5.7. I have everything running again, except the NIC...it keeps saying "Cable Unplugged" in the network settings. The router I am plugging into blinks up all three lights on the front once every 3 seconds or so. I have placed the ReatekR1000.kext into SLE, and into the Extras folder on the EFI partition. Still nothing. Is there anything else I can do...or is it dead hardware?
