Hi guys. Have a quick question. My Compaq Presario f500, will NOT pick up a driver. It was windows Vista, then I put on xp pro. Files and drivers did not pick up. Alot of googleing, I did get some the drivers for alot of them. Then I flip the machine over, where is say Service tag. I got a F551AU MODEL. tried that but still can not get a driver for UNKNOW. In the device manager Under Other Device these a UNKNOWN DEVICE. The wifi works fine. In fack I'm using the wifi now. In the device manager Two(2) item under network adapter Broadcom 802.11b/g WLAN & NVIDIA nForce networking controller Both are working. I Have a feeling it had something to do with th Ethernet connection. Thank guy and gals.
