1.11 Jumpers

1. Clear RTC RAM (CLRTC1)

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 RAM data in CMOS, that include

system setup information such as system passwords, is powered by the

onboard button cell battery.

To erase the RTC RAM:

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

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

pins 1-2 for about 5~10 seconds, then move the cap back to pins 2-3.

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.

Except when clearing the RTC RAM, never remove the cap on CLRTC1 jumper

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

(Default)

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 BIOS can automatically reset

parameter settings to default values.

2. USB device wake-up (3-pin USBPW12, USBPW34, USBPW56, USBPW78)

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 sleep mode (no

power to CPU, DRAM in slow refresh, power supply in reduced power mode).

All jumpers are set to pins 1-2 (+5V) by default because not all computers have

the appropriate power supply to support this feature.

The USBPW12 and USBPW34 jumpers are for the rear USB ports. The

USBPW56 and USBPW78 jumpers are for the internal USB header that you

can connect to the front USB ports.

1. This feature requires a power supply that can provide at least 2A on the

+5VSB lead when these jumpers are set to +5VSB. Otherwise, the system

does not power up.

Important notes on Serial ATA solution:

•

In legacy operating system (Win 98, WinME, WinNT, DOS)

environment, using SATA will disable one of the IDE channels from

ICH5 south bridge chipset. See BIOS section for correct setting.

• The Serial ATA cable is smaller and more flexible allowing easier

routing inside the chassis. The lower pin count of the Serial ATA

cable eliminates the problem caused by the wide, flat ribbon cables

of the Parallel ATA interface.

•

Hot plug support for Serial ATA drive and connections are not

available in this motherboard.

4. IDE connectors (40-1 pin PRI_IDE1, SEC_IDE1)

This connector supports the provided UltraDMA100/66/33 IDE ribbon cable.

Connect the cable’s blue connector to the primary (recommended) or secondary

IDE connector, then connect the gray connector to the UltraDMA100/66/33 slave

device (hard disk drive) and the black connector to the UltraDMA100/66/33 master

device. It is recommended that you connect non-UltraDMA100/66/33 devices to

the secondary IDE connector. If you install two hard disks, you must configure the

second drive as a slave device by setting its jumper accordingly. Refer to the hard

disk documentation for the jumper settings. BIOS supports specific device bootup.

If you have more than two UltraDMA100/66/33 devices, purchase another

UltraDMA100/66/33 cable. You may configure two hard disks to be both master

devices with two ribbon cables – one for the primary IDE connector and another

for the secondary IDE connector.

1. Pin 20 on each IDE connector is removed to match the covered hole on the

UltraDMA cable connector. This prevents incorrect orientation when you

connect the cables.

2. The hole near the blue connector on the UltraDMA100/66/33 cable is

intentional.

3. For UltraDMA100/66 IDE devices, use the 80-conductor IDE cable.

NOTE: Orient the red markings

(usually zigzag) on the IDE

ribbon cable to PIN 1.

2.2 BIOS Setup program

This motherboard supports a programmable firmware hub (FWH) that you can

update using the provided utility described in section “2.1 Managing and updating

your BIOS.”

Use the BIOS Setup program when you are installing a motherboard, reconfiguring

your system, or prompted to “Run Setup”. This section explains how to configure

your system using this utility.

Even if you are not prompted to use the Setup program, you may want to change

the configuration of your computer in the future. For example, you may want to

enable the security password feature or change the power management settings.

This requires you to reconfigure your system using the BIOS Setup program so

that the computer can recognize these changes and record them in the CMOS

RAM of the firmware hub.

The firmware hub 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 <Delete> 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, restart the system by pressing <Ctrl> +

<Alt> + <Delete>, or by pressing the reset button on the system chassis. You can

also restart by turning the system off and then back on. Do this last option only if

the first two failed.

The Setup program is designed to make it as easy to use as possible. It is a menu-

driven program, which means you can scroll through the various sub-menus and

make your selections from the available options using the navigation keys.

The default BIOS settings for this motherboard 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 Default Settings item under the Exit Menu. See

section “2.7 Exit Menu.”

The BIOS setup screens shown in this chapter are for reference purposes only,

and may not exactly match what you see on your screen.

3.3 ASUS Instant Music Lite

The motherboard is equipped with a BIOS-based audio playback feature called

Instant Music Lite. This feature is supported by the onboard audio AC’97

CODEC, and requires an optical drive (CD-ROM, DVD-ROM, or CD-RW).

1. Instant Music Lite only supports CDs in audio format.

2. Instant Music Lite does not work if you installed and enabled an add-on

sound card.

3. Instant Music Lite only supports PS/2 keyboard.

To enable ASUS Instant Music Lite:

1. Connect the analog audio cable from the optical drive (CD-ROM, DVD-ROM,

or CD-RW drive) to the 4-pin CD-In connector (labeled CD1) on the

motherboard. See section “1.12 Connectors” for the connector location.

Make sure to connect the CD-ROM audio cable. Otherwise, you cannot control

the audio volume using the Instant Music Lite function keys.

2. Turn on the system and enter BIOS by pressing the Delete key during the

Power On Self-Tests (POST).

3. In the Advanced Configuration menu, select the item Instant Music and set

it to Enabled. See section “2.4 Advanced Menu” in the user guide.

4. Highlight the Instant Music CDROM item and press Enter to display the

CD-ROM options. Select the CD-ROM drive that you wish to use for this

feature. See section “2.4 Advanced Menu” in the user guide.

If you have only one optical drive (either CD-ROM, DVD-ROM, or CD-RW)

installed in the system, you don’t have to set Instant Music CDROM item. BIOS

automatically detects and displays the installed drive type.

5. Save your changes and exit BIOS Setup.

1. The Scroll Lock LED is fixed to ON after enabling Instant Music.

2. The Caps Lock LED is turns ON when you pause the CD playback.

3. When set to Instant Music Lite mode, the system wake-up features (LAN,

keyboard, mouse, USB) are deactivated. In this case, power up the system

using the power switch.

4. If the system lost connection or did not detect any optical drive, the Instant

Music Lite feature turns OFF (disabled) automatically. A “beep” indicates

this condition.
