Is your network interface on-board? Which SiS chipset do you have (or which motherboard model)? Someone said in an earlier posting that newer revs of the on-board 900 emulation had problems, but it's always worked for me on my SiS735-based board.

The introduction to this section says "Please post a full output of lspci -v if your hardware is not detected, and all relevant information about your hardware." That's your next step.
