1 Headers

1. Clear RTC RAM (2-pin CLRTC)

This header 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 include system setup

information such as system passwords.

To erase the RTC RAM:

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

2. Use a metal object such as a screwdriver to short the two pins.

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

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

enter data.

• Ifthestepsabovedonothelp,removetheonboardbatteryandshortthetwopins

again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the

battery.

• YoudonotneedtocleartheRTCwhenthesystemhangsduetooverclocking.For

system failure due to overclocking, use the CPU Parameter Recall (C.P.R.) feature.

Shut down and reboot the system, then the BIOS automatically resets parameter

settings to default values.

2. RTC Battery header (2-pin BATT_CON)

This connector is for the lithium CMOS battery.

3. Chassis intrusion header (4-1 pin CHASSIS)

This header is for a chassis-mounted intrusion detection sensor or

switch. Connect one end of the chassis intrusion sensor or switch cable

to this connector. The chassis intrusion sensor or switch sends a high-

level signal to this connector when a chassis component is removed or

replaced. The signal is then generated as a chassis intrusion event.

By default, the pin labeled “Chassis Signal” and “Ground” are shorted

with a jumper cap. Remove the jumper caps only when you intend to use

the chassis intrusion detection feature.

2 Jumpers

1. Clear RTC RAM (3-pin CLRTC)

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 include system setup information such as system

passwords.

To erase the RTC RAM:

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

2. 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.

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

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

reenter data.

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

position. Removing the cap will cause system boot failure!

• Ifthestepsabovedonothelp,removetheonboardbatteryandmovethejumper

again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the

battery.

• YoudonotneedtocleartheRTCwhenthesystemhangsduetooverclocking.For

system failure due to overclocking, use the CPU Parameter Recall (C.P.R) feature.

Shut down and reboot the system so the BIOS can automatically reset parameter

settings to default values.

2. Intel®ME jumper (3-pin DIS_ME)

This jumper allows you to enable or disable the Intel®ME

function. Set this jumper to pins 1-2 to enable (default) the Intel®

ME function and to pins 2-3 to disable it.

3. USB device wake-up (3-pin USBPWF)

Set these jumpers to +5V to wake up the computer from S1 sleep

mode (CPU stopped, DRAM refreshed, system running in low power

mode) using the connected USB devices. Set to +5VSB to wake

up from S3 and S4 sleep modes (no power to CPU, DRAM in slow

refresh, power supply in reduced power mode).

• TheUSBdevicewake-upfeaturerequiresapowersupplythatcanprovide500mAon

the +5VSB lead for each USB port; otherwise, the system would not power up.

• ThetotalcurrentconsumedmustNOTexceedthepowersupplycapability(+5VSB)

whether under normal condition or in sleep mode.

4. Keyboard and USB device wake up (3-pin KB_USBPWB)

USB device wake-up feature. When you set this jumper to pins

2-3 (+5VSB), you can wake up the computer by pressing a key on

thekeyboard.ThisfeaturerequiresanATXpowersupplythatcan

supply at least 1A on the +5VSB lead, and a corresponding setting
