Via Rhine II NIC - VT6102 - Troubleshooting

I had several troubles with this NIC and SuSE 9.3... After many tests the disgnostic was bad PHY/MAC on the NIC wich comes builtin on a Biostar 8668 Mainboard. The message reported at boot was 0x786d status which means cable or transceiver problems, I disabled the onboard NIC and installed a PCI one which is working very fine. I just wrote this because there is too few documentation about PHY or MAC status codes. Good Luck!
