2. FEATURES
2.1.4 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 (requiresACPI 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.
•
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.

3.5 System Memory
This motherboard uses only Dual Inline Memory Modules (DIMMs). Two DIMM
sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic
Random Access Memory (SDRAM) of 16, 32, 64, 128, 256, or 512MB to form a
memory size between 16MB to 1GB. One side (with memory chips) of the DIMM
takes up one row on the motherboard. This motherboard also supports NEC’s Virtual
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.
When using all the four DIMM sockets, the Suspend-to-RAM (STR) feature
is not available.

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.

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

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.
Proceed to the next section for the steps on how to properly install a CPU.

3.6.1 CPU Installation
Follow these steps to install a CPU.
1. Locate the ZIP socket on the motherboard.
2. Unlock the socket by pressing the lever sideways then lifting it up to a 90°-100°
angle.
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. Carefuly insert the CPU into the socket 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. Secure the CPU into the socket by pushing the socket lever all the way down.
You will hear a click indicating that the lever is in place.
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.

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.
ASUS CUV4X-C User’s Manual
25
3. HARDWARE SETUP
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.

tween orange and green after the system’s if it complies with “green”
standards or if it has a power standby feature. The system will then run
power-on tests. While the tests are running, the BIOS will alarm beeps
or additional messages will appear on the screen. If you do not see any-
thing within 30 seconds from the time you turn on the power, the system
may have failed a power-on test. Recheck your jumper settings and con-
nections or call your retailer for assistance.

4.1 Managing and Updating Your BIOS
4.1.1 Upon First Use of the Computer System
It is recommended that you save a copy of the original motherboard BIOS
along with a Flash Memory Writer utility (AFLASH.EXE) to a bootable
floppy disk in case you need to reinstall the BIOS later. AFLASH.EXE is a
Flash Memory Writer utility that updates the BIOS by uploading a new
BIOS file to the programmable flash ROM on the motherboard. This file
works only in DOS mode. To determine the BIOS version of your mother-
board, check the last four numbers of the code displayed on the upper left-
hand corner of your screen during bootup. Larger numbers represent a newer
BIOS file.
1. Type FORMAT A:/S at the DOS prompt to create a bootable system
floppy disk. DO NOT copy AUTOEXEC.BAT & CONFIG.SYS to the
disk.
2. Type COPYD:\AFLASH\AFLASH.EXEA:\ (assuming D is your CD-
ROM drive) to copy AFLASH.EXE to the just created boot disk.
NOTE: AFLASH works only in DOS mode. It will not work with DOS
prompt in Windows and will not work with certain memory drivers that
may be loaded when you boot from your hard drive. It is recommended
that you reboot using a floppy.
3. Reboot your computer from the floppy disk. NOTE: BIOS setup must
specify “Floppy” as the first item in the boot sequence.
4. In DOS mode, type A:\AFLASH <Enter> to run AFLASH.
IMPORTANT! If “unknown” is displayed after Flash Memory:, the memory
chip is either not programmable or is not supported by theACPI BIOS and there-
fore, cannot be programmed by the Flash Memory Writer utility.

5. Select 1. Save Current BIOS to File from the Main menu and press
<Enter>. The Save Current BIOS To File screen appears.
6. Type a filename and the path, for example, A:\XXX-XX.XXX and then
press <Enter>.
4.1.2 Updating BIOS Procedures
WARNING! Only update your BIOS if you have problems with your mother-
board and you know that the new BIOS revision will solve your problems. Care-
less updating can result in your motherboard having more problems!
1. Download an updated ASUS BIOS file from the Internet (WWW or
FTP) (see ASUS CONTACT INFORMATION on page 3 for details)
and save to the disk you created earlier.
2. Boot from the disk you created earlier.
3. At the “A:\” prompt, type AFLASH and then press <Enter>.
4. At the Main Menu, type 2 and then press <Enter>. The Update BIOS
Including Boot Block and ESCD screen appears.
5. Type the filename of your new BIOS and the path, for example, A:\XXX-
XX.XXX, and then press <Enter>.
NOTE: To cancel this operation, press <Enter>.

6. When prompted to confirm the BIOS update, press Y to start the update.
7. The utility starts to program the new BIOS information into the flash
ROM. The boot block will be updated automatically only when neces-
sary. This will minimize the chance that a failed update will prevent
your system from booting up. When the programming is finished, Flashed
Successfully will be displayed.
8. Follow the onscreen instructions to continue.
WARNING! If you encounter problems while updating the new BIOS, DO NOT
turn off your system since this might prevent your system from booting up. Just
repeat the process, and if the problem still persists, update the original BIOS file
you saved to disk above. If the Flash Memory Writer utility was not able to
successfully update a complete BIOS file, your system may not be able to boot
up. If this happens, your system will need servicing.

4.2 BIOS Setup Program
This motherboard supports a programmable EEPROM that can be updated using
the provided utility as described in 4.1 Managing and Updating Your BIOS.
The utility is used if you are installing a motherboard, reconfiguring your system,
or prompted to “Run Setup”. This section describes how to configure your system
using this utility.
Even if you are not prompted to use the Setup program, at some time in the future
you may want to change the configuration of your computer. For example, you
may want to enable the Security Password Feature or make changes to the power
management settings. It will then be necessary to reconfigure your system using
the BIOS Setup program so that the computer can recognize these changes and
record them in the CMOS RAM of the EEPROM.
The EEPROM on the motherboard stores the Setup utility. When you start up the
computer, the system provides you with the opportunity to run this program. This
appears during the Power-On Self Test (POST). Press <Delete> to call up the Setup
utility. If you are a little bit late in pressing the mentioned key, POST will continue
with its test routines, thus preventing you from calling up Setup. If you still need to
call Setup, restart the system by pressing <Ctrl> + <Alt> + <Delete>, or by press-
ing the Reset button on the system chassis. You can also restart by turning the
system off and then back on again. But do so only if the first two methods fail.
The Setup program has been designed to make it as easy to use as possible. It is a
menu-driven program, which means you can scroll through the various sub-menus
and make your selections among the predetermined choices.
To access the BIOS Setup program, press the <Delete> key after
the computer has run through its POST.
NOTE: Because the BIOS software is constantly being updated, the following
BIOS screens and descriptions are for reference purposes only and may not re-
flect your BIOS screens exactly.

7.3 Glossary
1394
1394 is the IEEE designation for the high performance serial bus at 12.5, 25 or
50MBytes/sec speeds. This serial bus defines both a back plane physical layer and a
point-to-point cable-connected virtual bus. The primary application of the cable ver-
sion is the integration of I/O connectivity at the back panel of personal computers
using a low-cost, scalable, high-speed serial interface. The 1394 standard also pro-
vides new services such as live connect/disconnect capability for external devices
including disk drives, printers and hand-held peripherals such as scanners and cam-
eras. This is a new standard to complement the slower USB interface and to compete
with the more expensive SCSI interface.
AC97 (Audio Codec '97)
AC '97 is the next step in enabling PCs with audio quality comparable to consumer
electronics devices. The specification defines new cost-effective options to help in-
tegrate the components necessary to support next-generation auto-intensive PC ap-
plications such as DVD, 3-D multiplayer gaming and interactive music. The speci-
fication also defines new extensions supporting modem and docking to help both
desktop and mobile manufacturers adopt these new technologies more quickly and
cost-effectively. This specification uses software emulation to compete with the PCI
SoundBlaster specification.
ACPI (Advanced Configuration and Power Interface)
TheACPI specification defines a cross-platform interface designed to support many
operating systems. ACPI defines a flexible and abstract hardware interface that pro-
vides a standard way to integrate power management features throughout a PC sys-
tem, including hardware, operating system and application software. This enables
the system to automatically turn ON and OFF peripherals such as CD-ROMs, net-
work cards, hard disk drives, and printers, as well as consumer devices connected to
the PC such as VCRs, TVs, phones, and stereos. With this technology, peripherals
will also be able to activate the PC. For example, inserting a tape into a VCR can
turn on the PC, which could then activate a large-screen TV and high-fidelity sound
system.
AGP (Accelerated Graphics Port)
An interface specification that enables high-performance 3D graphics on mainstream
PCs. AGP was designed to offer the necessary bandwidth and latency to perform
texture mapping directly from system memory.

BIOS (Basic Input/Output System)
BIOS is a set of routines that affect how the computer transfers data between com-
puter components, such as memory, disks, and the display adapter. The BIOS in-
structions are built into the computer’s read-only memory. BIOS parameters can be
configured by the user through the BIOS Setup program. The BIOS can be updated
using the provided utility to copy a new BIOS file into the EEPROM.
Bit (Binary Digit)
Represents the smallest unit of data used by the computer. A bit can have one of two
values: 0 or 1.

7. APPENDIX
Boot
Boot means to start the computer operating system by loading it into system memory.
When the manual instructs you to “boot” your system (or computer), it means to
turn ON your computer. “Reboot” means to restart your computer. When using Win-
dows 95 or later, selecting “Restart” from “Start | Shut Down...” will reboot your
computer.
Bus Master IDE
PIO (Programmable I/O) IDE requires that the CPU be involved in IDE access and
waiting for mechanical events. Bus master IDE transfers data to/from the memory
without interrupting the CPU. Bus master IDE driver and bus master IDE hard disk
drives are required to support bus master IDE mode.
Byte (Binary Term)
One byte is a group of eight contiguous bits. A byte is used to represent a single
alphanumeric character, punctuation mark, or other symbol.
COM Port
COM is a logical device name used by to designate the computer serial ports. Point-
ing devices, modems, and infrared modules can be connected to COM ports. Each
COM port is configured to use a different IRQ and address assignment.
Concurrent PCI
Concurrent PCI maximizes system performance with simultaneous CPU, PCI and
ISA bus activities. It includes multi-transaction timing, enhanced write performance,
a passive release mechanism and support for PCI 2.1 compliant delayed transac-
tions. Concurrent PCI provides increased bandwidth, reduced system latencies, im-
proves video and audio performance, and improves processing of host based appli-
cations.
CPU (Central Processing Unit)
The CPU, sometimes called “Processor,” actually functions as the “brain” of the
computer. It interprets and executes program commands and processes data stored
in memory. Currently, there are socket 370 (for Pentium III FC-PGA and Celeron-
PPGA), socket 7 (for Pentium, AMD, Cyrix, IBM), slot 1 (for Pentium II and III),
slot 2 (for Xeon), and slot A (for AMD) processors.
Device Driver
A device driver is a special set of instructions that allows the computer’s operating
system to communicate with devices such as VGA, audio, printer, or modem.
DOS (Disk Operating System)
DOS is the foundation on which all other programs and software applications oper-
ate, including Windows. DOS is responsible for allocating system resources such as
memory, CPU time, disk space, and access to peripheral devices. For this reason,
DOS constitutes the basic interface between you and your computer.
DRAM (Dynamic Random Access Memory)
There are several different types of DRAM such as, EDO DRAM (Extended Data
Output DRAM), SDRAM (Synchronous DRAM), and RDRAM (Rambus DRAM).
Flash ROM
The flash ROM is designed to be a resident program and can be updated by a spe-
cific programming method. Normally, the flash ROM is used for system BIOS which
initiates hardware devices and sets up necessary parameters for the OS. Since the
contents of flash ROM can be modified, users are able to update the BIOS by them-
selves.
IDE (Integrated Drive Electronics)
IDE devices integrate the drive control circuitry directly on the drive itself, elimi-
nating the need for a separate adapter card (in the case for SCSI devices). UltraDMA/
33 IDE devices can achieve up to 33MB/Sec transfer.

LPT Port (Line Printer Port)
Logical device name reserved by DOS for the computer parallel ports. Each LPT
port is configured to use a different IRQ and address assignment.
MMX
A set of 57 new instructions based on a technique called Single Instruction, Multiple
Data (SIMD), which is built into the new Intel Pentium PP/MT (P55C) and Pentium
II (Klamath) CPU as well as other x86-compatible microprocessors. The MMX in-
structions are designed to accelerate multimedia and communications applications,
such as 3D video, 3D sound, video conference.
OnNow
The OnNow design initiative is a comprehensive, system-wide approach to system
and device power control. OnNow is a term for PC that is always ON but appears
OFF and responds immediately to user or other requests. The OnNow design initia-
tive involves changes that will occur in the Microsoft Windows operating system,
device drivers, hardware, and applications, and also relies on the changes defined in
the Advanced Configuration and Power Interface (ACPI) specification.
PC100
SDRAM is Intel's goal is to ensure that memory subsystems continue to support
evolving platform requirements and to assure that memory does not become a bottle-
neck to system performance. It is especially important to ensure that the PC memory
roadmap evolves together with the performance roadmaps for the processors, I/O
and graphics.
PCI Bus (Peripheral Component Interconnect Local Bus)
PCI bus is a specification that defines a 32-bit data bus interface. PCI is a standard
widely used by expansion card manufacturers.
PCI Bus Master
The PCI Bus Master can perform data transfer without local CPU help and further-
more, the CPU can be treated as one of the Bus Masters. PCI 2.1 supports concur-
rent PCI operation to allow the local CPU and bus master to work simultaneously.
Plug and Play BIOS
The ISA bus architecture requires the allocation of memory and I/O address, DMA
channels and interrupt levels among multiple ISA cards. However, configuration of
ISA cards is typically done with jumpers that change the decode maps for memory
and I/O space and steer the DMA and interrupt signals to different pins on the bus.
Further, system configuration files may need to be updated to reflect these changes.
Users typically resolve sharing conflicts by referring to documentation provided by
each manufacturer. For the average user, this configuration process can be unreli-
able and frustrating. Plug and play (PnP) BIOS eliminates the ISA add-on card hard-
ware conflict problem. The PnP BIOS uses a memory block to define and remember
each card's configuration, which allows the user to change the card's IRQs and DMA
in BIOS either automatically or manually.
POST (Power On Self Test)
When you turn ON the computer, it will first run through the POST, a series of
software-controlled diagnostic tests. The POST checks system memory, the mother-
board circuitry, the display, the keyboard, the diskette drive, and other I/O devices.
PS/2 Port
PS/2 ports are based on IBM Micro Channel Architecture. This type of architecture
transfers data through a 16-bit or 32-bit bus. A PS/2 mouse and/or keyboard may be
used on ATX motherboards.
RDRAM (Rambus DRAM)
Developed by Rambus, Inc., this type of memory can deliver up to 1.6GB of data
per second. RDRAM is the first interface standard that can be directly implemented
on high performance VLSI components such as, CMOS DRAMs, memory control-
lers, and graphics/video ICs.

7. APPENDIX
ROM (Read Only Memory)
ROM is nonvolatile memory used to store permanent programs (called firmware)
used in certain computer components. Flash ROM (or EEPROM) can be repro-
grammed with new programs (or BIOS).
SCSI (Small Computer System Interface)
High speed multi-threaded I/O interface defined by the X3T9.2 committee of the
American National Standards Institute (ANSI) for connecting many peripheral de-
vices. The standard started from 10MBytes/sec to 160MBytes/sec available today.
SDRAM (Synchronous DRAM)
The SDRAM features a fully synchronous operation referenced to a positive edge
clock whereby all operations are synchronized at a clock input which enables the
coexistence of high performance and a simple user interface. SDRAM takes memory
access away from the CPU's control; internal registers in the chips accept the re-
quest, and let the CPU do something else while the data requested is assembled for
the next time the CPU talks to the memory. As they work on their own clock cycle,
the rest of the system can be clocked faster. There is a version optimized for video
cards, and main memory for motherboards.
SPD for SDRAM module
Serial Presence Detect (SPD) is most like an ID detect for SDRAM module, it using
a EEPROM component on DIMM module for storing module configuration infor-
mation inside. The Serial Presence Detect function is implemented using a 2048 bit
EEPROM component. This nonvolatile storage device contains data programmed
by the DIMM manufacturer that identifies the module type and various SDRAM
organization and timing parameters.
SSE (Streaming SIMD Extensions)
A set of new instructions added to existing architectures that enables a better visual
experience with an accelerated 3D geometry pipeline and support for new applica-
tions, such as real-time video encoding and speech recognition.
System Disk
A system disk contains the core file of an operating system and is used to boot up the
operating system.
UltraDMA
Ultra DMA/33 is a "synchronous DMA" protocol designed by Intel. This function is
included into Intel's PIIX4 chipset. The traditional IDE transfer only uses one edge
of the data stroke as the data transfer. Ultra DMA/33 uses both edges of data strobe
when the data is transferred. Hence, the data transfer rate is double of the PIO mode
4 or DMA mode 2 (16.6MB/s x2 = 33MB/s) on ATA-2 devices.
Ultra ATA/66, also known as Ultra DMA/66, is an extension of current Ultra ATA/
33 interface. This new high-speed interface has doubled the Ultra ATA/33 burst data
transfer rate to 66.6 Mbytes/sec and maximized disk performance under current PCI
local bus environment
USB (Universal Serial Bus)
A 4-pin serial cable bus that allows up to 127 plug and play computer peripherals
such as keyboard, mouse, joystick, scanner, printer, modem, and monitor to share a
bandwidth through a host scheduled token based protocol. This allows attaching or
detaching while the host and other peripherals are in operation. Supports synchro-
nous and asynchronous transfer types over the same set of wires up to 12Mbit/sec.
USB 2.0 provides twice the transfer rate compared to USB 1.0 and competes with
the 1394 standard.
Wake-On-LAN
The computer automatically wakes up upon receiving a wake-up packet through a
Network interface when it is under power soft-off, suspend or sleep mode.
