I've installed JaS 10.4.8 SSE2/SSE3 sucessfully on my AMD Athlon 3500+ PC. All works fine but the only thing that I can't get working is my Ethernet card. The Motherboard has a built-in Realtek 8100C card, but this was not recognized during the installation. Therefore I tried a Realtek 8139 PCI card but this one is also not recognized. I see success stories of RTL1839 and OS X 10.4.8 (in fact I believe my AppleTV has a RTL8139 card). Anyone an idea what I can try? Any help is much appreciated.
