2. FEATURES

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 the power button is pressed 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 allows a computer to be turned on

remotely through an internal or external modem. With this benefit on-hand, users
can access vital information from their computers anywhere.

Intelligence

2. FEATURES

• 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

ASUS ASIC through the CPU’s internal thermal diode to 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.

• Chassis Intrusion Detection: Supports chassis-intrusion monitoring through

the ASUS ASIC. A chassis intrusion event is kept in memory on battery power
for more protection.

Layout Contents

3. H/W SETUP

W ARNING! Computer motherboards and expansion cards contain very delicate

Integrated Circuit (IC) chips. To avoid damaging them due to static electricity,
follow these precautions whenever you work on your computer.

1. Unplug the computer when working on the internal components.

2. Use a grounded wrist strap or touch a safely grounded object or to a metal
object, such as the power supply case, before handling computer components.

3. Hold components by the edges and try not to touch the IC chips on them.

4. Whenever you uninstall any component, place the components on a grounded
antistatic pad or in the bag that came with the components.

5. Before you install or r emove any component, ensure that the A TX power

supply is switched off or the power cord is detached from the power
supply. Failure to do so may cause severe damage to the motherboard,

peripherals, and/or components.
(TIP: When lit, the onboard LED indicates that the system is in suspend or
soft-off mode, not powered OFF. See illustration below.)

2) CPU External Frequency Selection (DIP_F Switches 1–5)

This option tells the clock generator what frequency to send to the CPU, DRAM,
and the PCI bus. This allows the selection of the CPU’s External frequency (or
BUS Clock). The BUS Clock multiplied by the Frequency Multiple equals the
CPU’s Internal frequency (the advertised CPU speed).

3.5 System Memory

This motherboard supports unbuffered Double Data Rate (DDR) Dual Inline Memory
Modules (DIMMs). Four DDR DIMM sockets are available for 2.5V (power level)
DDR Synchronous Dynamic Random Access Memory (DDR SDRAM) of 64, 128,
256, 512MB, or 1GB densities for a system memory configuration up to 4GB.

WARNING! Make sure that the DIMM you use can handle the specified DDR

SDRAM speeds, otherwise, the computer will not boot.

Install non-ECC memory in any combination as follows:

DIMM Location 184-pin DDR DIMM Total Memory

Socket 1 (Rows 0&1) 64MB, 128MB, 256MB, 512MB, (1GB) x1
Socket 2 (Rows 2&3) 64MB, 128MB, 256MB, 512MB, (1GB) x1

3.5.1 DDR SDRAM Notes

The DDR SDRAM technology evolved from the mainstream PC66, PC100, PC133
memory known as Single Data Rate (SDR) SDRAM. DDR memory however, has
the ability to perform two data operations in one clock cycle, thus providing twice
the throughput of SDR memory . For example, a 200MHz DDR DIMM will support
a 100MHz memory bus, and a 266MHz DDR DIMM will support a 133MHz memory
bus.

A DDR DIMM has the same physical dimensions as an SDR DIMM, but it has a
184-pin footprint compared to the 164-pin of the SDR DIMM. Also, a DDR DIMM
is single notched while an SDR DIMM is double notched. Therefore, a DDR DIMM
is not backward compatible with SDR, and should be installed only in a socket
specially designed for DDR DIMMs.

System Memory

DDR DIMMs are available in both unbuffered and registered versions.

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 the components.

A 184-pin DDR SDRAM DIMM has a single notch near the center. The number of
pins are different on either side of the notch so the module only fits in one direction.
Insert a DDR DIMM into the DDR socket as shown.

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.

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.

until it fits in place.

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.

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.

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.

CAUTION! When installing two CPUs, make sure that the CPUs are identical.

When using only one CPU, make sure to install a terminator on the second CPU
socket. DO NOT install heatsink and fan on the terminator!

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 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. H/W SETUP

ASUS CUV266-D User’s Manual 25

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.
