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 the clear CMOS button to clear the
BIOS configuration and reset the CMOS values to factory defaults when needed. The Clear Battery button has DIP
