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.
