one parallel port with EPP and ECP capabilities. UART2 can also be directed
from COM2 to the Infrared Module for wireless connections.

• Enhanced ACPI & Anti-Boot Virus Protection: Programmable BIOS (Flash

EEPROM), offering enhanced ACPI for W indows 98 compatibility , built-in firm­ware-based virus protection, and autodetection of most devices for virtually au­tomatic setup.

• IrDA: Supports an optional infrared port module for wireless interface.

• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-

ter busses to the memory and processor.

• Smart BIOS: 2Mb firmware provides Vcore and CPU/SDRAM frequency ad-

justments, boot block write protection, and HD/SCSI/MO/ZIP/CD/Floppy boot
selection. Power supply is autodetected to enable/disable suspend-to-RAM, elimi­nating the need to make jumper adjustments.

• Integrated Infrared Support: Integrated IR supports an optional remote con-

trol package for wireless interfacing with external peripherals, personal gad­gets, or an optional remote controller.

• Desktop Management Interface (DMI): Supports DMI through BIOS, which

allows hardware to communicate within a standard protocol creating a higher
level of compatibility. (Requires DMI-enabled components.)

Specifications

2. FEATURES

2.1.2 Optional Components

The following onboard components are optional at the time of purchase:

• Smart Audio: Provides C-Media Electronics Inc.’s CMI-8738 PCI 3D Exten-

sion Positional Audio Chip. With this chip onboard, no external CODEC is
needed. CMI-8738 supports legacy audio (SB16™), FM emulator/DLS wavetable
music synthesis, and HRTF 3D positional audio functions, and PCtel® HSP56
(1789) interface.Compatible with A3D™ and DirectSound™ 3D, CMI8738 thus
meets PC98® requirements, and supports professional digital audio interface.

• One T ouch Management: Supports an optional ASUS iPanel, an easy to access

box with system information LEDs, front I/O ports, and space reserved for a
hard disk drive. With an ASUS iPanel, you can monitor your computer’s vital
components.

• LCD/TV Output: The LCD/TV interface can support either an optional LCD

module for LCD output or a TV-out module for TV output.

ASUS CUV4X-V User’s Manual 9

2. FEATURES

2.1.3 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 indows95/98/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.

2.1.4 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-V User’s Manual

2. FEATURES

2.1.5 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.

3.3 Hardware Setup Procedure

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

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

6. Setup the BIOS Software

3.4 Motherboard Settings

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:

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.

3.7 Expansion Cards

WARNING! Unplug your power supply when adding or removing expansion

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

3.7.1 Expansion Card Installation Procedure

1. Read the documentation for your expansion card and make any necessary hard­ware or software settings for your expansion card, such as jumpers.

2. Remove your computer system’s cover and the bracket plate on the slot you
intend to use. Keep the bracket for possible future use.

3. Carefully align the card’s connectors and press firmly.

4. Secure the card on the slot with the screw you removed above.

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.

ASUS CUV4X-V User’s Manual 27

Both ISA and PCI expansion cards may require IRQs. System IRQs are available to
cards installed in the ISA expansion bus first, then any remaining IRQs are available
to PCI cards. Currently, there are two types of ISA cards.

The original ISA expansion card design, now referred to as legacy ISA cards, re­quires that you configure the card’s jumpers manually and then install it in any
available slot on the ISA bus. To see a map of your used and free IRQs in W indows
98, the Control Panel icon in My Computer, contains a System icon, which gives
you a Device Manager tab. Double-clicking on a specific hardware device gives
you the Resources tab which shows the Interrupt number and address. Double-click
Computer to see all the interrupts and addresses for your system. Make sure that no
two devices use the same IRQ or your computer will experience problems when
those two devices are in use at the same time.

To simplify this process, this motherboard complies with the Plug and Play (PNP)
specification which was developed to allow automatic system configuration when-

Expansion Cards

3. H/W SETUP

ever a PNP-compliant card is added to the system. For PNP cards, IRQs are as­signed automatically from those available.

3. HARDWARE SETUP

If the system has both legacy and PNP ISA cards installed, IRQs are
assigned to PNP cards from those not used by legacy cards. The PCI and PNP con­figuration of the BIOS setup utility can be used to indicate which IRQs are being
used by legacy cards. For older legacy cards that do not work with the BIOS, you
can contact your vendor for an ISA Configuration Utility.

An IRQ number is automatically assigned to PCI expansion cards after those used
by legacy and PNP ISA cards. In the PCI bus design, the BIOS automatically as­signs an IRQ to PCI cards that require an IRQ. To install a PCI card, you need to set
the INT (interrupt) assignment. Since all the PCI slots on this motherboard use an
INTA #, be sure that the jumpers on your PCI cards are set to INT A.

Assigning DMA Channels for ISA Cards

Some ISA cards, both legacy and PNP , may also need to use a DMA (Direct Memory
Access) channel. DMA assignments for this motherboard are handled the same way
as the IRQ assignment process described earlier. You can select a DMA channel in
the PCI and PNP configuration section of the BIOS Setup utility.

IMPORTANT: To avoid conflicts, reserve the necessary IRQs and DMAs for

legacy ISA cards (see 4.4.3 PCI Configuration. Choose Yes in IRQ xx Used By
ISA and DMA x Used By ISA for those IRQs and DMAs you want to reserve).

3.7.4 Audio Modem Riser (AMR) Slot

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 audio chip controller. The
motherboard’s onboard audio chip controller (optional) must be disabled when using
a primary AMR.

NOTE: An AMR is not included with this motherboard.

IMPORTANT: The AMR slot of this motherboard shares the same expansion slot

as the ISA slot. Because of this and its location, the slot can only accept a specially
