Great info here. Thanks everyone. I have a N54L running trantor's 4.3 now. Just wanted to edit the vender file with the real MAC address but got stuck. Went through previous posts but didn't get the answer. Maybe it's just too trivial and people didn't even think it was an issue.
Anyways, how did you guys find out the physical MAC address? Do I need a monitor attached to the N54L and get into the BIOS? Any info is welcome!
