For some features needed, users can change the jumper settings on this mother�oard to modify
them. This section explains how to use the various functions of this mother�oard �y changing the
jumper settings. Users should read the following content carefully prior to modifying any jumper
setting.
Description of Jumpers
1. For any jumper on this motherboard, pin 1 can be identiied by the bold silkscreen next to it.
However, in this manual, pin 1 is simply la�eled as “1”.
2. The following table explains different types of the jumper settings. "Closed" means placing a
jumper cap on the two pins to temporarily short them. The shorting can also �e done �y touch-
ing two pins �y a screwdriver for a few seconds, �ut using jumper cap is recommended. It can
prevent hazardous ESD (Electrical Static Discharge) pro�lem.
Clear CMOS Jumper: CLR_CMOS
The mother�oard uses CMOS RAM to store the �asic hardware information (such as BIOS data,
date, time information, hardware password...etc.). Clear CMOS data is the fast way to go �ack to
factory default when the BIOS settings were mistakenly modiied.
The steps to clear CMOS data are :
1. Turn off the computer, unplug the power cord from the power outlet.
2. Remove jumper cap from pins 2
-3, put it onto pins 1-
2 to short them. This will clear CMOS
data.
3. Return the setting to its original with pins 2
-3 closed.
4. Plug in the power cord to your computer and turn it on.
5. Go to BIOS Setup to conigure new system as described in next chapter.
