Secure Backup UEFI
Whenever one of the ROM images are outdated or corrupted, switch to the other flash
ROM and execute Secure Backup UEFI to duplicate the current working ROM image to
the secondary flash ROM..
This motherboard has two BIOS chips, an active BIOS (BIOS_A) and a backup
BIOS (BIOS_B), which enhances the safety and stability of your system. Use "Secure
Backup UEFI" to duplicate a working copy of the BIOS files to the active BIOS to
ensure normal system operation. Normally, the system will work on the active BIOS.
However if the active BIOS is corrupted or damaged, after several failed boot
attempts, the backup BIOS will take over. For safety issues, users are not able to
update the backup BIOS manually. Users may refer to the BIOS LEDs (BIOS_A_LED
or BIOS_B_LED) to identify which BIOS is currently activated.
