BIOS Selection Jumper
(BIOS_SEL1)
(see p.1, No. 24)
his motherboard has two BIOS onboard, a main BIOS (BIOS_A) and a backup
BIOS (BIOS_B), 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. Ater that, short pin1 and
pin2 again, then use “Secure Backup UEFI“ in BIOS setup utility to copy the BIOS
ile 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_LED or BIOS_B_LED) to identify which BIOS is activated
currently.
