2.15 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 system to original settings (factory settings).
Step 1: Turn off the PC and disconnect the power adapter.
Step 2: Connect the 1st and 2nd pin of JCMOS for 10 seconds through the jumper cap then
disconnect.
Step 3: Restart the device, press the <DEL> button to enter the BIOS, load the optimal default value,
save, and exit the settings.
