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 USB_PWR1 & USB_PWR2 &
USB_PWR3 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.
