Installing the Motherboard
Checking Jumper Settings

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.
