This motherboard has two BIOS chips, a primary BIOS (BIOS_A) and a
backup BIOS (BIOS_B), which enhances the safety and stability of your
system. Normally, the system will work on the primary BIOS. However, if the
primary BIOS is corrupted or damaged, just lip the BIOS Selection Switch
to “B”, then the backup BIOS will take over on the next system boot. After
that, use “Secure Backup UEFI” in the UEFI Setup Utility to duplicate a
working copy of the BIOS iles to the primary BIOS to ensure normal system
operation. 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.
