BIOS Switch and BIOS LED Indicators
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 SB switch allows enabling or disabling of the Dual BIOS function.
The LED indicator (MBIOS_LED/BBIOS_LED) shows which 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 1 2 3
