Hardware Installation
Jumpers are built on the mainboard to allow the user flexibility to configure the
mainboard settings to meet their specific requirements. The mainboard comes
with three jumpers. When there is no jumper cap inserted into the jumper it
is called “OPEN.” When a cap is inserted into the jumper it is known as a
“SHORT.” Below are examples of short settings or open settings on a jumper.

2.9.1. JP1: KB/MS Power
Type: 3 pin
Default: Pin 1 and Pin 2 Short
Some keyboards may not follow standard specifications. If you find you are
having problems with your keyboard, change the settings on Pin 2 and Pin 3.
This might help you to solve the problem.
2.9.2. JP2: CPU FSB
Type: 2 pin
Default: Short
This allows you to select the speed of your CPU. If you are using a 200 MHz
FSB CPU on your mainboard then you need to short this jumper. If you are
using a 266 MHz FSB CPU you need to open this jumper.
2.9.3. JP3: Clear CMOS
Type: 3 pin
Default: Pin 1 and Pin 2 Short
If you have made an improper setting in the BIOS setup and your computer is
not functioning, or if you have forgotten your password, you can use this
jumper to clear the CMOS memory and to reconfigure your system.
To clear the CMOS, please follow these instructions:
1.
Turn the system power off and unplug your computer;
2.
Insert the jumper cap on Pin 2 and Pin 3 for 3 ~ 5 seconds;
3.
Pull out the jumper cap and replace it on Pin 1 and Pin 2;
4. Turn your PC on and run the BIOS setup program.
