Chapter 3 Jumpers & Headers Setup

3.1 Checking Jumper Settings

• For a 2-pin jumper, plug the jumper cap on both

pins will make it CLOSE (SHORT). Remove the

jumper cap, or plug it on either pin (reserved for

future use) will leave it at OPEN position.

• For 3-pin jumper, pin 1~2 or pin 2~3 can be

shorted by plugging the jumper cap in.

How to identify the PIN1 jumpers?

Please check the mainboard carefully, the PIN1

is marked by "1" or white thick line.

3.2 CMOS Memory Clearing Header

The time to clear the CMOS memory occurs when (a)

the CMOS data becomes corrupted, (b) you forgot

the supervisor or user password preset in the BIOS

menu, (c) you are unable to boot-up the system

because the CPU ratio/clock was incorrectly set in the

BIOS menu, or (d) whenever there is modication on

the CPU or memory modules.

This header uses a jumper cap to clear the CMOS

memory and have it recongured to the default

values stored in BIOS.

• Pins 1 and 2 shorted

(Default): Normal

operation.

• Pins 2 and 3 shorted:

Clear CMOS memory.

To clear the CMOS memory and load in the default values:

1. Power off the system.

2. Set pin 2 and pin 3 shorted by the jumper cap. Wait for a few seconds. Set the jumper

cap back to its default settings --- pin 1 and pin 2 shorted.

3. Power on the system.

4. For incorrect CPU ratio/clock settings in the BIOS, press <Del> key to enter the BIOS

setup menu right after powering on system.

5. Set the CPU operating speed back to its default or an appropriate value.

6. Save and exit the BIOS setup menu.
