technology to enable Pentium 4 processors auto throttling function. When auto
throttling is enabled, the CPU with throttle down to 50% of its duty cycle when
the CPU temperature reaches the threshold and return to 100% of its duty cycle
when temperature lowers to normal level. This function ensures the best
performance and reliability.

• Fan Status Monitoring and Alarm: To prevent system overheat and system
damage, the CPU, PWR, and CHASSIS fans can be monitored for RPM and
failure. All the fans are set for its normal RPM range and alarm thresholds.

• T emperature Monitoring and Alert: T o prevent system overheat and system dam-
age, this motherboard supports processor thermal sensing and auto-protection.

• Voltage Monitoring and Alert: System voltage levels are monitored to ensure
stable current to critical motherboard components. Voltage specifications are
more critical for future processors, so monitoring is necessary to ensure proper
system configuration and management.

Intelligence

2. FEATURES

• System Resources Alert: Today’s operating systems, such as Windows 98/
Millenium, and W indows NT/2000, require much more memory and hard drive
space to present enormous user interfaces and run large applications. The onboard
hardware ASUS ASIC in conjunction with either the bundled ASUS PC Probe
or Intel LDCM will warn the user before the system resources are used up to
prevent possible application crashes. Suggestions will give the user information
on managing their limited resources more efficiently.

• Dual Function Power Button: Through BIOS, the power button can be defined
as the “Stand by” (ie.: Suspend or Sleep) button or as the Soft-Off (see ATX
Power / Soft-Off Switch Lead in 3.8 Connectors for more information) button.
Regardless of the setting, pushing the power button for more than 4 seconds will
enter the Soft-Off mode.

• Check Motherboard Settings

• Install Memory Modules

• Install the Central Processing Unit (CPU)

• Install Expansion Cards

• Connect Ribbon Cables, Panel Wires, and Power Supply

3. H/W SETUP

Getting Started

3. HARDWARE SETUP

WARNING! Computer motherboards and expansion cards contain very delicate

Integrated Circuit (IC) chips. To protect them against damage from static electric­ity, you should follow some precautions whenever you work on your computer.

1. Unplug your computer when working on the inside.

2. Use a grounded wrist strap before handling computer components. If you do
not have one, touch both of your hands to a safely grounded object or to a metal
object, such as the power supply case.

3. Hold components by the edges and try not to touch the IC chips, leads or con­nectors, or other components.

4. Place components on a grounded antistatic pad or on the bag that came with the
component whenever the components are separated from the system.

5. Ensure that the ATX power supply is switched off before you plug in or
remove the ATX power connector on the motherboard.

WARNING! Make sure that you unplug your power supply when adding or

removing system components. Failure to do so may cause severe damage to
your motherboard, peripherals, and/or components.

2. With the ejectors in the open position (as shown), push down gently but firmly
on the memory module until it snaps into place. The guides on the socket’s
ejectors should go through the two mounting notches on the module and the
ejectors should close. If necessary, push the ejectors inward to secure the mod-

ule in place.

Removing Memory

T o release a memory module, push both ejectors outward and pull the module straight
up and out of the RIMM sockets.

WARNING! RIMM modules become extremely hot during operation. To re-

duce the risk of personal injury from hot surfaces, allow the modules to cool off
before removing them.

3.5 Central Processing Unit (CPU)

The motherboard provides a ZIF Socket for the P4 Socket 423 CPU. The CPU that
came with the motherboard should have a fan attached to it to prevent overheating.

If not, then purchase a fan before turning on the system.

open it by pulling the lever gen­tly sideways away from the
socket. Then lift the lever up­wards. The socket lever must be
fully opened (90 to 100 degrees).

2. Insert the CPU with the correct
orientation. The gold arrow of
the CPU must be oriented to­ward the outer corner of the
socket base nearest to the tip of
the lever handle.

Step 2: Mount the Heatsink:

1. Open the retaining clips. Place the
heatsink on the CPU. The heatsink
should entirely cover the CPU. Then
close and snap the clips into the locked
position plastic heatsink support braces
have built-in retaining clips, right. With
the added weight of the CPU fan and
heatsink locking brace, no extra force is
required to keep the CPU in place.

2. Connect the CPU fan cable to the fan connector. (See 3.1 Motherboard

Layout / 3.8 Connectors).

CAUTION! Take care not to scrape the motherboard surface when

mounting a clamp-style processor fan, or else damage may occur . When
mounting a heatsink onto your CPU, make sure that exposed CPU
capacitors do not touch the heatsink, or else damage may occur! Refer
to heatsink/CPU documentation.

3. H/W SETUP

WARNING! Be sure that there is sufficient air circulation across the

processor’s heatsink by regularly checking that your CPU fan is work­ing. Without sufficient circulation, the processor could overheat and
damage both the processor and the motherboard. You may install an
auxiliary fan, if necessary.

3.6 Expansion Cards

WARNING! Unplug your power supply when adding or removing expansion

cards or other system components. Failure to do so may cause severe damage to
both your motherboard and expansion cards (see 3.3 Hardware Setup Proce-
dure for more information).

3.6.1 Expansion Card Installation Procedure

1. Read the documentation for your expansion card and make any necessary hard­ware or software settings for your expansion card, such as jumpers.

2. Remove your computer system’s cover and the bracket plate on the slot you
intend to use. Keep the bracket for possible future use.

3. Carefully align the card’s connectors and press firmly.

4. Secure the card on the slot with the screw you removed above.

5. Replace the computer system’s cover.

6. Set up the BIOS if necessary
(such as IRQ xx Used By ISA: Yes in PNP AND PCI SETUP)

7. Install the necessary software drivers for your expansion card.

3. HARDWARE SETUP

3.6.2 Assigning IRQs for Expansion Cards

Some expansion cards need an IRQ to operate. Generally, an IRQ must be exclu­sively assigned to one use. In a standard design, there are 16 IRQs available but
most of them are already in use, leaving 6 IRQs free for expansion cards. If your
motherboard has PCI audio onboard, an additional IRQ will be used. If your moth-

erboard also has MIDI enabled, another IRQ will be used, leaving 4 IRQs free.
