If the system switched to Secondary BIOS to boot up, it can be asserted that the Primary BIOS is having a
severe problem that it failed to function. Before users determine that the BIOS chip is completely corrupted
and unusable, it would be advisable to try to update the Primary BIOS.
Flashing a BIOS needs to be carefully completed, especially pertaining to a corrupted BIOS, which can lead to
an unusable system if done incorrectly.

1. When the system enters the BIOS menu, BIOS will disable the watchdog function. In another words, even
over the set time limit in the BIOS menu, the system will not reboot automatically.
2. Dual BIOS feature cannot work with the BIOS BOOT Guard function.
3. To update and reflash BIOS, it is mandatory that both BIOS will need to be updated. This action is to avoid
ME code variations on both of the BIOS, which can lead to unexpected risks and errors.
