Selection Switch, allowing users to clear the CMOS values or boot from diferent
BIOS.
Clear CMOS Switch
(CLRCBTN)

his function is workable only when you power of your computer and unplug the
power supply.
BIOS Selection Switch
(BIOS_SEL1)
(see p.6, No. 27)
his 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. Ater 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.
