1. Clear RTC RAM (CLRTC)
This jumper allows you to clear the Real Time Clock (RTC) RAM in the
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 the CMOS, which includes system setup
information such as the 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 to enter the BIOS
setup program, then 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.

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 these jumpers 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.
3. Keyboard power (3-pin KBPWR)
This jumper allows you to enable or disable the keyboard wake-up feature.
Set this jumper to pins 2-3 (+5VSB) to wake up the computer by pressing
a key on the keyboard (the default is the Space Bar). This feature requires
an ATX power supply that can supply at least 1A on the +5VSB lead, and a
corresponding setting in the BIOS.
These connectors are for the Serial ATA signal cables for Serial ATA drives.
• Install Windows® XP Service Pack 1 before using Serial ATA drives.
• When using the connectors in IDE mode, connect the primary (boot) hard disk
drive to the SATA1 connector.
2. COM port connector (10-1pin COM1)
This connector is for a serial (COM) port. Connect the serial port module
cable to this connector, then install the module to a slot opening at the back
of the system chassis.

The fan connector support cooling fans of 350mA~2000mA (24W max.).
Connect the fan cable to the fan connector on the motherboard, ensuring that
the black wire of each cable matches the ground pin of the connector.
DO NOT forget to connect the CPU fan cable to the CPU fan connector.
Insufcient air ow inside the system may damage the motherboard
components. It is not a jumper! DO NOT place a jumper cap on the CPU fan
connector!

We recommend that you connect a high-denition front panel audio module to
this connector to get the motherboard’s high-denition audio capability.

6. ATX power connectors (24-pin EATXPWR, 4-pin ATX12V)
These connectors are for ATX power supply plugs. The plugs from the power
supply are designed to t these connectors in only one orientation. Find the
proper orientation and push down rmly until the connectors completely t.
•
DO NOT forget to connect the 4-pin ATX +12 V power plug; otherwise, the
system will not boot.
• We recommend that you use a PSU with a higher power output when
conguring a system with more power-consuming devices. The system
may become unstable or may not boot up if the power is inadequate.
• Ensure that your power supply unit (PSU) can provide at least the minimum
power required by your system.

8. Chassis intrusion connector (4-1 pin CHASSIS)
This connector 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.

4.2 BIOS setup program
This motherboard supports a programmable rmware chip that you can update
using the provided utility described in section 4.1 Managing and updating your
BIOS.
Use the BIOS Setup program when you are installing a motherboard, reconguring
your system, or prompted to “Run Setup”. This section explains how to congure
your system using this utility.
Even if you are not prompted to use the Setup program, you can change the
conguration of your computer in the future. For example, you can enable the
security password feature or change the power management settings. This
requires you to recongure your system using the BIOS Setup program so that the
computer can recognize these changes and record them in the CMOS RAM of the
SPI chip.
The rmware chip on the motherboard stores the Setup utility. When you start up
the computer, the system provides you with the opportunity to run this program.
Press <Del> during the Power-On Self-Test (POST) to enter the Setup utility;
otherwise, POST continues with its test routines.
If you wish to enter Setup after POST, reboot the system by doing any of the
following procedures:
• Restart using the OS standard shut-down procedure.
• Press <Ctrl>+<Alt>+<Del> simultaneously.
• Press the reset button on the system chassis.
• Press the power button to turn the system off then back on.
Using the power button, reset button, or the <Ctrl>+<Alt>+<Del> keys to
force reset from a running operating system can cause damage to your data
or system. We recommend to always shut-down the system properly from the
operating system.
The Setup program is designed to make it as easy to use as possible. Being a
menu-driven program, it lets you scroll through the various sub-menus and make
your selections from the available options using the navigation keys.
• The default BIOS settings apply for most conditions to ensure optimum
performance. If the system becomes unstable after changing any BIOS
settings, load the default settings to ensure system compatibility and
stability. Select the Load Setup Defaults item under the Exit menu. See
section 4.8 Exit Menu.
• The BIOS setup screens shown in this section are for reference purposes only.
They may not exactly match what you see on your screen.
• Visit the ASUS website at www.asus.com to download the latest BIOS le.
