the NVM in question is a single part that the entire machine (VGA, BIOS, LAN, Manageability, AHCI, etc) all use.
I couldn't tell you how to verify if something else is mapping over the top of the LAN area of the NVM. The only reports I've heard are that the LAN NVM is corrupted. If you managed to corrupt the BIOS area, the machine wouldn't boot.
