I'm not pretty sure about this...
Since for many motherboards it is able to use a EEPROM programmer to rescue a broken BIOS.
Maybe they know which block not to overwrite, or maybe the S/N and MAC address is stored in a separate NVRAM?
Not sure what is the case for Intel boards though.
I guess my best try is to buy another second-handed board and clone the BIOS image,
but I just really don't need another spare motherboard...
Anyone have experience with Intel support center?
Are they able to help with this kind of situation if I'm willing to pay a few bucks?
