2.1.2 Performance

• ACPI Ready: Advanced Configuration Power Interface (ACPI) provides more

Energy Saving Features for operating systems that support OS Direct Power
Management (OSPM) functionality. With these features employed in the OS,
PCs can be ready around the clock but comply with energy saving standards. To
fully utilize the ACPI benefits, use an ACPI-supported OS such as Windows 98.

• PC’99 Compliant: Both the BIOS and hardware levels of ASUS smart series

motherboards are PC’99 compliant. The new PC’99 requirements for systems
and components are based on the following high-level goals: Support for Plug­n-Play compatibility and power management for configuring and managing all
system components, and 32-bit device drivers and installation procedures for
Windows 95/98/NT. Color-coded connectors and descriptive icons make
identification easy as required by PC’99.

• High-Speed Data Transfer Interface: Support for UltraDMA/100 through the

onboard IDE bus master controller. doubles the UltraDMA/33 burst transfer
rate to 66.6MB/s. UltraDMA/100 is backward compatible with DMA/66, DMA/
33, and other existing DMA devices to save the need to upgrade current EIDE/
IDE drives. (UltraDMA/66 requires a 40-pin 80-conductor cable).

• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI master

busses to the memory and processor.

• VCM/SDRAM Optimized Performance: This motherboard supports the new

generation memory , NEC 64Mb Virtual Channel Memory (VCM) Synchronous
Dynamic Random Access Memory (SDRAM), that is compatible to the industry
standard SDRAM. The VCM core design provides up to 50% higher SDRAM
speed at reduced power consumption of about 30%. This motherboard also
supports the standard SDRAM for a the data transfer rate of up to 1.064GB/s using
PC133-compliant SDRAMs and up to 800MB/s using PC100-compliant
SDRAMs.

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 95/98/

NT and OS/2, 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 (on Pentium III and
Celeron) 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.

3.3 Hardware Setup Procedure

Complete the following steps before using your computer:

1. Check motherboard settings

2. Install memory modules

3. Install the Central Processing Unit (CPU)

4. Install Expansion Cards

5. Connect ribbon cables, panel wires, and power supply cables

6. Configure the BIOS parameter settings

3.4 Motherboard Settings

This section tells you how to change motherboard function settings through the
switches and/or jumpers.

WARNING! 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 remove any component, ensur e 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.)

3.5 System Memory

This motherboard uses only Dual Inline Memory Modules (DIMMs). Four DIMM
sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic
Random Access Memory (SDRAM) of 16, 32, 64, 128, 256, 512MB, or 1GB densities
for a system memory configuration of 32MB up to 4GB. One side (with memory
chips) of the DIMM takes up one row on the motherboard. This motherboard also
supports NEC’s Virtual Channel SDRAMs and Enhanced Memory System’s High-
speed DRAMs.

IMPORTANT (see General DIMM Notes below for more)

• SDRAMs used must be compatible with the current Intel PC133 SDRAM
specifications.

• DO NOT mix registered SDRAMs with VCM SDRAMs.

Install memory in any combination as follows:

DIMM Location 168-pin DIMM Total Memory

Socket 1 (Rows 0&1) SDRAM 16, 32, 64, 128, 256, 512MB, 1GB x1
Socket 2 (Rows 2&3) SDRAM 16, 32, 64, 128, 256, 512MB, 1GB x1
Socket 3 (Rows 4&5) SDRAM 16, 32, 64, 128, 256, 512MB, 1GB x1

3.5.1 General DIMM Notes

• DIMMs that have more than 18 chips are not supported on this motherboard.

• For the system CPU bus to operate 100MHz/133MHz, use only PC100-/PC133-

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.

3.5.2 Memory Installation

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).

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.

System Memory

3. H/W SETUP

The DIMMs must be 3.3Volt unbuffered SDRAMs. To determine the DIMM type,
check the notches on the DIMMs (see the figure below).

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.

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.

CUV4X-DLS

Gold Arrow

®

CUV4X-DLS Socket 370

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.

CAUTION! Be careful not to scrape the motherboard when mounting/unmounting

a clamp-style processor fan to avoid damaging the motherboard.

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.

WARNING! If you are using only one CPU on the

motherboard, make sure to install a CPU terminator on
the unused CPU socket. But DO NOT install heatsink and
fan on the CPU terminator! Doing so will cause irreparable
damage to the CPU and motherboard.

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

Expansion Cards

ASUS CUV4X-DLS User’s Manual 27

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
