Installing the Motherboard

Checking Jumper Settings & Clear CMOS Button

The following illustration shows the location of the motherboard jumpers. Pin 1 is

labeled.

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_F1~2 & USBPWR_R1~2

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.
