Clear CMOS/SW1 Button
Clear CMOS Button is used to clear the saved system setup conguration stored in the CMOS
chip. All the settings will be erased and restored to the factory defaults after pressing this
button. On this motherboard, there are two buttons which built-in this function. One is the
SW1 button located on the I/O back panel and the other is the Clear CMOS button located
next to the Reset Button.
Power Button
In addition to the soft power switch provided in JF1, your motherboard is equipped with a
'soft' power button on the motherboard. This switch works the same way as the soft power
switch on JF1.
