The BIOS switch (BIOS_SW) allows users to easily select a different BIOS for boot up or overclocking, helping
to reduce BIOS failure during overclocking. The DualBIOS switch (SB) allows enabling or disabling of the Dual
BIOS function. The LED indicator (MBIOS_LED/BBIOS_LED) shows which BIOS is active.

MBIOS_LED (The main BIOS is active)
BBIOS_LED (The backup BIOS is active)

Quick Buttons
This motherboard has four quick buttons: Power, Reset, Clear CMOS, and Clear Battery. The power button and
reset button allow users to quickly turn on/off or reset the computer in an open-case environment when they want
to change hardware components or conduct hardware testing. Use this button to clear the BIOS configuration
and reset the CMOS values to factory defaults when needed. The Clear Battery button has the same function
as removing the battery from the motherboard.
PW_SW: Power Button
RST_SW: Reset Button
CMOS_SW: Clear CMOS Button

：
Clear Battery Button
• Always turn off your computer and unplug the power cord from the power outlet before using
the clear CMOS button.
• Always turn off the power of the power supply before using the clear battery button. After pressing
this button, make sure to wait for five minutes before you turn on the computer.
•
Do not use the clear CMOS or clear battery button when the system is on, or the system may
shutdown and data loss or damage may occur.
•
After system restart, go to BIOS Setup to load factory defaults (select Load Optimized Defaults) or
manually configure the BIOS settings (refer to Chapter 2, "BIOS Setup," for BIOS configurations).
