Jumper Settings
1. To avoid the system unstability after clearing CMOS, we recommend
users to enter the main BIOS setting page to “Load Default Settings” and
then “Save & Exit Setup”.
2. Make sure the power supply provides enough 5VSB voltage before
selecting the 5VSB function.
3. It is required that users place the USBPWR_R & USBPWR_F cap onto
2-3 pin rather than 1-2 pin as default if you want to wake up the com-
puter by USB/PS2 KB/Mouse.
