    This does not work on a Dell 6510 in Linux. If no wire connected or connection to wireless (can’t as has wpa2 required). Tried to find MAC in bios but only gives the ethernet MAC. I cannot bring up in Windows 7 as must have domain connection for login. Booted with FC8 live figuring I could get mac address to add to routers’ mac table. Man this is making me think as ifconfig -a only brings up the loopback address. Feel real dumb about now.
