I'm not sure what's going on with my onboard nic, but none of the operating systems I run can find the NIC automatically (like it did before). I have a
Biostar TA690G AM2 5.x motherboard and the NIC uses Realtec drivers. I've had this board for over a year and I've gone through Windows {Vista,7}, Fedora {8,9,10,11,12} without any NIC issues.
I'm dual-booting Windows 7 and Linux (Fedora 12). Before I ran a crack program for Windows 7 (product activation) both systems were able to identify the NIC and pull the proper drivers. I ran the crack program, rebooted my machine and from that point on I've had to manually find the device and the drivers.
I did some research and it looks like I might have blown some sort of memory that's on the NIC, which is used for identifying it. Does an onboard NIC have such a feature? I'm not very knowledgeable when it comes to hardware.
