ASUS CUV4X User’s Manual 9
2. FEATURES
2.1.2 Special Features
• ACPI Ready: Advanced Configuration Power Interface (ACPI) provides more
Energy Saving Features for operating systems that support OS Direct Power
Management (OSPM) functionality . W ith these features implemented in the OS,
PCs can be ready around the clock, yet satisfy all the energy saving standards.
To fully utilize the benefits of ACPI, an ACPI-supported OS, such as Windows
98 must be used.
2. FEATURES
Performance
• Easy Installation: Incorporates BIOS that supports autodetection of hard disk
drives, PS/2 mouse, and Plug and Play devices to make the setup of hard disk
drives, expansion cards, and other devices virtually automatic.
• PC’99 Compliant: Both the BIOS and hardware levels of ASUS smart series
motherboards meet PC’99 compliancy. The new PC’99 requirements for systems and components are based on the following high-level goals: Support for
Plug and Play compatibility and power management for configuring and managing all system components, and 32-bit device drivers and installation procedures for W indows 95/98/NT. Color -coded connectors and descriptive icons make
identification easy as required by PC’99.
• Symbios SCSI BIOS: Supports optional ASUS SCSI controller cards through
the onboard SYMBIOS firmware.
2.1.3 Performance Features
• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-
ter busses to the memory and processor.
• High-Speed Data Transfer Interface: IDE transfers using UltraDMA/33 Bus
Master IDE can handle rates up to 33MB/s. This motherboard with its chipset
and support for UltraDMA/66 doubles the UltraDMA/33 burst transfer rate to
66.6MB/s. UltraDMA/66 is backward compatible with both DMA/33 and DMA
and with existing DMA devices and systems so there is no need to upgrade
current EIDE/IDE drives and host systems. (UltraDMA/66 requires a 40-pin
80-conductor cable to be enabled and/or for UltraDMA Mode 4.)
• VCM/SDRAM Optimized Performance: This motherboard supports a new gen-
eration memory, NEC’s 64Mb Virtual Channel Memory (VCM) Synchronous
Dynamic Random Access Memory (SDRAM), which is compatible to the industry standard SDRAM. The VCM’s core design provides up to 50% higher
SDRAM speed at reduced power consumption of about 30%. This motherboard
also supports standard SDRAM, which increases the data transfer rate (1.064GB/s
max using PC133-compliant SDRAMs and 800MB/s max using PC100-compliant SDRAMs).

ASUS CUV4X User’s Manual
2. FEATURES
2.1.4 Intelligence
• Auto Fan Off: The system fans will power 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 sec-
onds 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, power supply, and system fans can be monitored for RPM
and failure. All fans are set for its normal RPM range and alarm thresholds.
• Message LED (requires ACPI OS support): T urbo LEDs now act as informa-
tion providers. Through the way a particular LED illuminates, the user can determine if there are messages waiting in the mailbox. A simple glimpse provides
useful information to the user.
Intelligence
2. FEATURES
• 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 from anywhere in the world!
• 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
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.
• Temperature Monitoring and Alert: CPU temperature is monitored by the
ASUS ASIC through the CPU’s internal thermal diode (on Pentium III, Pentium
II (Deschutes), and PPGA370 Celeron in conjunction with the ASUS S370 Series CPU card) 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.

This section explains in detail how to change your motherboard’s function settings
through the use of switches and/or jumpers.
W ARNING! 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 re-
moving system components. Failure to do so may cause severe damage to your
motherboard, peripherals, and/or components. The onboard LED when lit acts as
a reminder that the system is in suspend or soft-off mode and not powered OFF.

3.5 System Memory (DIMM)
This motherboard uses only Dual Inline Memory Modules (DIMMs). Three sockets
are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random
Access Memory (SDRAM) of 8, 16, 32, 64, 128, 256, or 512MB to form a memory
size between 8MB to 1.5GB. One side (with memory chips) of the DIMM takes up
one row on the motherboard. This motherboard also supports NEC’s V irtual Channel
(VC) SDRAMs and Enhanced Memory System’s High-speed DRAMs (HSDRAMs).
Memory speed setup is recommended through SDRAM Configuration under “Chipset
Features Setup”.
IMPORTANT (see General DIMM Notes below for more)
• SDRAMs used must be compatible with the current Intel PC133 SDRAM
specification.
• DO NOT attempt to 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 8, 16, 32, 64, 128, 256, 512MB x1
Socket 2 (Rows 2&3) SDRAM 8, 16, 32, 64, 128, 256, 512MB 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 SPD (Serial Presence Detect) 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.

WARNING! Make sure that you unplug your power supply when adding or
removing memory modules or other system components. Failure to do so may
cause severe damage to both your motherboard and expansion cards (see 3.3
Hardware Setup Procedure for more information).
Insert the module(s) as shown. Because the number of pins are different on either
side of the breaks, the module will only fit in the orientation shown. DRAM SIMM
modules have the same pin contacts on both sides. SDRAM DIMMs have different
pin contacts on each side and therefore have a higher pin density.

3.6 Central Processing Unit (CPU)
The motherboard provides a ZIF Socket 370. The CPU that came with the motherboard should have a fan attached to it to prevent overheating. If this is not the case,
then purchase a fan before you turn on your system.
WARNING! Be sure that there is sufficient air circulation across the processor’s
heatsink by regularly checking that your CPU fan is working. W ithout sufficient
circulation, the processor could overheat and damage both the processor and the
motherboard. You may install an auxiliary fan, if necessary.
To install a CPU, first turn off your system and remove its cover. Locate the ZIF
socket and open it by first pulling the lever sideways away from the socket then
upwards to a 90-degree angle. Insert the CPU with the correct orientation as shown.
The notched corner should point towards the end of the lever . Because the CPU has
a corner pin for two of the four corners, the CPU will only fit in the orientation as
shown. The picture is for reference only; you should have a CPU fan that covers the
face of the CPU. W ith the added weight of the CPU fan, no force is required to insert
the CPU. Once completely inserted, close the socket’s lever while holding down the
CPU.

NOTE: Do not forget to set the correct Bus Frequency and Multiple (frequency
multiple setting is available only on unlocked processors) for your Socket 370 processor or else boot-up may not be possible. Socket 370 processors provide internal
thermal sensing so that a socket mounted thermal resistor is not needed.
CAUTION! Be careful not to scrape the motherboard when mounting a clamp-

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 will
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.

This connector supports a specially designed audio and/or modem card called an AMR.
Main processing is done through software and controlled by the motherboard’s sys-
tem chipset. This provides an upgradeable audio and/or modem solution at an incredibly low cost. There are two types of AMR, one defined as primary and another defined as secondary. This motherboard uses the primary channel so that a secondary
AMR can coexist without the need to disable the onboard CODEC. The motherboard’s
onboard CODEC (optional) must be disabled when using a primary AMR.
