Board and Pin Assignments 7

2.3.1 Clear CMOS (JCMOS1)

This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can

clear the CMOS memory of date, time, and system setup parameters by erasing the

CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS,

which includes system setup information such as system passwords.

To erase the RTC RAM:

1. Turn OFF the computer and unplug the power cord.

2. Remove the onboard battery.

3. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3

for about 5~10 seconds, then move the cap back to pins 1-2.

4. Re-install the battery.

5. Plug the power cord and turn ON the computer.

6. Hold down the <Del> key during the boot process and enter BIOS setup to re-enter

data.

Caution

Except when clearing the RTC RAM, never remove the cap on this jumper

default position. Removing the cap will cause system boot failure!

Note

You do not need to clear the RTC when the system hangs due to

overclocking. For system failure due to overclocking, use the C.P.R. (CPU

Parameter Recall) feature. Shut down and reboot the system so the BIOS

can automatically reset parameter settings to default values.

2.3.2 AT/ATX Power Mode Selection (JPSON)

This jumper allows you to select AT mode or ATX mode.

2.3.3 LVDS Backlight Power Selection (JLVDS_BKL1)

This jumper allows you to select LVDS backlight power.
