(see p.1, No. 20)
is motherboard has two BIOS onboard, a main BIOS (BIOS_A1) and a backup
BIOS (BIOS_B1), which enhances protection for the safety and stability of your
system. Normally, the system works on the main BIOS. However, if the main BIOS
is corrupted or damaged, please use a jumper cap to short pin2 and pin3, then
the backup BIOS will take over on the next system boot. Aer that, use “Secure
Backup UEFI“ in BIOS setup utility to copy the BIOS le to the main BIOS to
ensure normal system operation. For the sake of system safety, users cannot
update the backup BIOS manually. Users may refer to the BIOS LED (BIOS_A_
LED1 or BIOS_B_LED1) to identify which BIOS is activated currently.
