Jumper Settings
Connecting two pins with a jumper cap is SHORT; removing a jumper cap from
these pins, OPEN.
CLR_CMOS: Clear CMOS Jumper
Use this jumper to clear the contents of the CMOS memory. You may need to clear
the CMOS memory if the settings in the Setup Utility are incorrect and prevent
your motherboard from operating. To clear the CMOS memory, disconnect all the
power cables from the motherboard and then move the jumper cap into the CLEAR
setting for a few seconds.
Note: To avoid the system unstability after clearing CMOS, we recommend
users to enter the main BIOS setting page to “Load Optimal De-faults”
and then “Save Changes and Exit”.

selecting the SB5V function.
2. It is required that users place the USBPWR_F & USBPWR_R cap onto 2-
3 pin rather than 1-2 pin as default if you want to wake up the computer
by USB/PS2 KB/Mouse.
