1.5 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.

SHORT OPEN

OPEN

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

shorted by plugging the jumper cap in.

Pin 1~2 SHORT

1.5.1 CMOS Memory Clearing Header and Backup Battery

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,

CPU ratio/clock was incorrectly set in the BIOS menu,

or (d) whenever there is modification on the CPU or

memory modules.

This header uses a jumper cap to clear the CMOS

memory and have it reconfigured 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.

※ Another easy way to clear the CMOS memory can be done by switching

“EZ-CCMOS1”, see the section of “Connecting Rear Panel I/O Devices” in this

manual for detail.

※ The C.C. POST Code appears when either the external “EZ-CCMOS1” switch or

the internal “CCMOS1” jumper is not set to its normal position.
