• Auto CPU Throttling Function: Incorporated into this motherboard is a new
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.

ATX12V power supply is recommended for this motherboard. For typical system
configurations, an ATX12V power supply that can supply at least 230W and at least

8.5A on the +12V lead is required. For heavily-loaded configurations, an ATX12V
power supply that can supply at least 300W is required.

Before using your computer, you must complete the following steps:

• 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.

IMPORTANT

1. The memory configuration of channel A (RIMMA1 and RIMMA2) and chan­nel B (RIMMB1 and RIMMB2) must be identical (see below).

2. C-RIMMs (Continuity RIMM) must be used to complete the sockets that are
not populated by RDRAMs. A C-RIMM is necessary to avoid breaking the
signal lines, which are a serial connection in a Rambus interface, such as
used in this motherboard. This assures the electrical integrity of a Rambus
interface.

3. When C-RIMMs are required, it is recommended that they be inserted into
RIMMA2 and RIMMB2.

3. HARDWARE SETUP

Step 1: Mount the Black Plastic Heatsink Support Braces:

1. Insert the four black plastic collars from

the top through to the bottom of the
motherboard. Insert the white plastic
plugs into the middle of the black
plastic collars and pop them firmly out
the bottom of the motherboard. This
instruction applies to both types of
heatsink support clips in steps 2a and 2b.

Step 2a: Mount Heatsink Using Built-in Retaining Clips:

1. Open the retaining clips. Place the
heatsink on the CPU. The heatsink
should entirely cover the CPU. The
plastic heatsink support braces have
built-in retaining clips, right. Close and
snap the clips into the locked position.
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.

3.6 Expansion Cards

In the future, you may need to install expansion cards. The motherboard has five
PCI expansion slots to support these cards. Follow the steps in the next section
when installing expansion cards.

W ARNING! Unplug the system power cord when adding or removing expansion

cards or other system components. Failure to do so may cause severe damage to
both the motherboard and expansion cards.

3.6.1 Installing an Expansion Card

1. Read the documentation that comes with the expansion card and make any
necessary hardware settings for the card before installing it.

2. Remove the system unit cover and the bracket plate on the slot you intend to use.
Keep the screw for later use.

3. Align the card connectors with the slot and press firmly until the card fits in
place.

4. Secure the card to the slot with the screw you removed earlier.

5. Replace the system cover.

6. Change the necessary BIOS settings, if any.
(see section 4.4.3 PCI Configuration to change the settings.)

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

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 motherboard also

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

3.7 External Connectors

WARNING! Some pins are used for connectors or power sources. These are

clearly distinguished from jumpers in the Motherboard Layout. Placing jumper
caps over these connector pins will cause damage to your motherboard.

IMPORTANT: Ribbon cables should always be connected with the red stripe to

Pin 1 on the connectors. Pin 1 is usually on the side closest to the power connec­tor on hard drives and CD-ROM drives, but may be on the opposite side on
floppy disk drives. Check the connectors before installation because there may
be exceptions. IDE ribbon cables must be less than 46 cm (18 in.), with the
second drive connector no more than 15 cm (6 in.) from the first connector.
