Intelligence
2.1.3 Intelligence
• Auto Fan Off: The system fans powers off automatically even in sleep mode.
This function reduces both energy consumption and system noise, and is an
important feature in implementing silent PC systems.
• Dual Function Power Button: Pushing the power button for less than 4 seconds
when the system is in the working state places the system into one of two states:
sleep mode or soft-off mode, depending on the BIOS or OS setting (see PWR
Button < 4 Secs in 4.5 Power Menu). When you press the power button for
more than 4 seconds, the system enters the soft-off mode regardless of the BIOS
setting.
• Fan Status Monitoring and Alarm: To prevent system overheat and system
damage, the CPU and system fans can be monitored for RPM and failure. All
fans are set for its normal RPM range and alarm thresholds.
• Power LED (requir es ACPI OS support): The power LED indicates the system
status.
• Remote Ring-On (requires modem): This feature allows you to turn off the
computer remotely through an internal or external modem. With this benefit on-
hand, users can access vital information from their computers anywhere.
• System Resources Alert: Today’s operating systems such as Windows 98/ME
and Windows NT/2000, require much more memory and hard drive space to
present enormous user interfaces and run large applications. The system resource
monitor warns the user before the system resources are used up to prevent possible
application crashes. Suggestions provide the user some information on managing
their limited resources more efficiently.
• Temperature Monitoring and Alert: CPU temperature is monitored by the
VT82C686B prevent system overheat and system damage.
• Voltage Monitoring and Alert: System voltage levels are monitored to ensure
stable voltage to critical motherboard components. Voltage specifications are
more critical for future processors, so monitoring is necessary to ensure proper
system configuration and management.

compliant DIMMs.
• ASUS motherboards support Serial Presence Detect (SPD) DIMMs. This is the
memory of choice for best performance vs. stability.
• SDRAM chips are generally thinner with higher pin density than EDO (Extended
Data Output) chips.
• BIOS shows SDRAM memory on bootup screen.
• Single-sided DIMMs come in 16, 32, 64,128, 256MB; double-sided come in 32, 64,
128, 256, 512MB.
W ARNING! Make sure that the DIMM you use can handle the specified SDRAM
speeds, otherwise the computer will not boot.

3. HARDWARE SETUP
Insert the module(s) into the DIMM sockets as shown. Because the number of pins
are different on either side of the breaks, the module only fits in one direction. SDRAM
DIMMs have different pin contacts on each side and have a higher pin density than
DRAM SIMMs.
The notches on the DIMM shifts between left, center, or right to identify the type
and also to prevent the wrong type from being inserted into the DIMM slot on the
motherboard. You must tell your retailer the correct DIMM type before purchasing.
This motherboard supports four clock signals per DIMM.
The DIMMs must be 3.3Volt unbuffered SDRAMs. To determine the DIMM type,
check the notches on the DIMMs (see the figure below).
WARNING! Make sure that you unplug the power supply when adding or
removing memory modules or other system components. Failure to do so may
cause severe damage to both the motherboard and expansion cards (see 3.3
Hardware Setup Procedure for more information).

3.6 Central Processing Unit (CPU)
The motherboard comes with a ZIF Socket for the supported CPUs listed in section
2.1.1 Specifications. The following illustration shows the CPU socket location on
the motherboard and the correct CPU orientation.
Note in the illustration that CPUs have marks (usually a notch or a gold mark on one
corner) to help you identify the proper orientation and enable you to correctly install
a CPU. It is important that you match the marked corner of the CPU with the
corresponding corner on the socket so as not to damage the CPU pins.
The CPU picture above is for reference only. Usually, when you buy a CPU, the
heatsink and fan are already attached to the CPU. If a heatsink and fan did not come
with the package, make sure you obtain one before installing the CPU.
Proceed to the next section for the steps on how to properly install a CPU.
CAUTION! Be careful not to scrape the motherboard when mounting/unmounting
a clamp-style processor fan to avoid damaging the motherboard.
WARNING! You must install the proper heatsink and fan to the CPU. Failure to
do so will cause the CPU to overheat and may damage both the CPU and the
motherboard. Install an auxillary fan, if necessary.

3.6.1 CPU Installation
Follow these steps to install a CPU.
1. Locate the ZIF socket on the
motherboard.
2. Unlock the socket by pressing the
lever sideways then lifting it up to a
90°-100° angle.
5. When the CPU is in place, press it firmly on the socket while you push down the
socket lever to secure the CPU. The lever clicks on the socket indicating that it
is locked.
6. Attach the heatsink and fan to the CPU, if they were not pre-installed by the
vendor . Refer to the installation instructions that came with the heatsink and fan.
CAUTION! The CPU fits only in one orientation. DO NOT force the CPU into
the socket to prevent bending the pins and damaging the CPU. If the CPU does
not fit completely, check its orientation or check for bent pins.
NOTE: Do not forget to set the correct Bus Frequency and Multiple (frequency
multiple setting is available only on unlocked processors) for the processor to avoid
start-up problems.
3. Position the CPU above the socket
such that its notched or marked
corner matches the socket corner
near the end of the lever, while
making sure that the CPU is parallel
to the socket.
4. Carefully insert the CPU into the
socket until it fits in place.

3.7 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.
WARNING! 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.
3.7.1 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 chassis cover and the bracket plate on the slot you intend to use
(assuming that the motherboard is already installed in a chassis). 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.

3.7.2 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.
IMPORTANT: If using PCI cards on shared slots, make sure that the drivers support
“Share IRQ” or that the cards do not need IRQ assignments. Conflicts arise between
the two PCI groups that will make the system unstable or cards inoperable.
The following table lists the default IRQ assignments for standard PC devices. Use
this table when configuring your system and for resolving IRQ conflicts.
