Onboard Buttons, Switches, and LEDs

BIOS Switches and BIOS LEDs
The DualBIOS switch (SB) allows enabling or disabling of the Dual BIOS function. 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 LED indicator (MBIOS_LED/BBIOS_LED) shows which BIOS is active.

This motherboard has 3 quick buttons: power button, reset button and clear CMOS button. 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 CMOS button.
