Hardware Auto Start
Please note that this jumper function is similar to the " State After G3" function in BIOS. When
the latter is set to S0 State, the device will also start automatically after power is connected.
2.16 CMOS Clearance/Retention (Screen Printing: JCMOS)
CMOS is powered by onboard button batteries. Clearing CMOS will permanently remove the
previous system settings and restore the board to the original (factory settings) system settings.
Step 1: Turn off the PC and disconnect the power adapter.
Step 2: Use the jumper cap to connect the 1st and 2nd header of CLR_CMOS for about 10

seconds, then disconnect.
Step 3: When restarting the device, press the <Del> button to enter the BIOS, load the optimal
default value, save, and exit the settings.
