2.7 Smart Switches
The motherboard has four smart switches: Power Switch, Reset Switch, Clear CMOS
Switch and BIOS Selection Switch, allowing users to quickly turn on/off the system,
reset the system, clear the CMOS values or switch between BIOS A and BIOS B.
Power Switch
(PWRBTN)
(see p.1, No. 8)
Reset Switch
(RSTBTN)
(see p.1, No. 9)
Clear CMOS Switch
(CLRCBTN)
(see p.1, No. 7)
This function is workable only when you power off your computer and unplug the power
supply.
BIOS Selection
Switch
(BIOS_SEL1)
(see p.1, No. 29)
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 flip 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 files 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.
