Notice: BIOS SPI ROM
1. The Intel® Management Engine has already been integrated into this system board. Due to
the safety concerns, the BIOS (SPI ROM) chip cannot be removed from this system board and
used on another system board of the same model.
2. The BIOS (SPI ROM) on this system board must be the original equipment from the factory
and cannot be used to replace one which has been utilized on other system boards.
3. If you do not follow the methods above, the Intel® Management Engine will not be up-
dated and will cease to be effective.
Note:
a. You can take advantage of flash tools to update the default configuration of the
BIOS (SPI ROM) to the latest version anytime.
b. When the BIOS IC needs to be replaced, you have to populate it properly onto the
system board after the EEPROM programmer has been burned and follow the
technical person's instructions to confirm that the MAC address should be burned
or not.
