I'm going to try to give you guys as much information as possible so that hopefully somebody can help me. I bought a Biostar P4M900-M4 socket 478 motherboard an 8600GT XXX and 2Gigs of RAM. Everything installed okay except for the onboard LAN. I am running Windows XP Home, and after reactivating my copy of windows, I installed my drivers. It seemed to go alright. Except I can't get the Onboard LAN to work.
I have ruled out the possibility of hardware failure by using a bootable version of Linux, it picked up on all my hardware right away, except for the special settings for the 8600GT (understandable). I was able to surf the web perfectly. Whenever I plug in the CAT5 to the RJ45, I get both LEDs solid. They do not blink. Under Linux they blink like normal during data transfer.
I even tried to install a PCI LAN card, and I was met with the same Code 31 error in device manager. The same thing happened on the LEDs of this card as well.
I have tried multiple drivers (read: 13) and none have worked. The board wants to give drivers for a VIA Rhine II. I've tried every "compatible driver" but after they are done installing, they just give me the same message.
As of now, I am looking into how to Flash a BIOS. The BIOS version is from 8/28/07, so I don't know if it will help.
If I can provide any more info that might help, don't be afraid to ask. I just want to play some Counterstrike.
Any help would be greatly appreciated.
