I've got an Onboard NIC SIS 900 pci fast ethernet adapter. It was running fine in windows 98se. I upgraded to winxp professional. The adapter installed fine. and shows its running ok in the device manager. The prob is that the system tray shows the network cable is unplugged. I tried ipconfig and it says media unplugged. Anyone have a clue how to fix this without buying a new NIC? It was working fine in win98se.
