stable current to critical motherboard components. Voltage specifications are
more critical for future processors, so monitoring is necessary to ensure proper
system configuration and management.
•
•
System ResourcesAlert! Today’s operating systems such as Windows 98, Win-
dows NT, and OS/2, require much more memory and hard drive space to present
enormous user interfaces and run large applications. The system resource moni-
tor will warn the user before the system resources are used up to prevent pos-
sible application crashes. Suggestions will give the user information on manag-
ing their limited resources more efficiently.
Dual Function Power Button! Through the BIOS, the power button can be
defined as the “Standby” (a.k.a. Suspend or Sleep) button or as the Soft-Off (see
ATX Power Switch Lead in 3.8 External Connectors for more information)
button. Regardless of the setting, pushing the power button for more than 4
seconds will enter the Soft-Off mode.
•
•
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 any information from their computers from anywhere in the world!
Message LED (requires ACPI OS support)! Chassis LEDs now act as infor-
mation providers. Through the way a particular LED illuminates, the user can
determine the stage the computer is in. A simple glimpse provides useful infor-
mation to the user.
•
Peripheral Power Up! Keyboard or Mouse power up can be enabled or dis-
abled through BIOS setup to allow the computer to be powered ON using your

3.5.1 General DIMM Notes
• When this motherboard operates at 100MHz, PC100-compliant modules must be
used because of the strict timing issues involved under this speed.
• 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, 64,128MB; double-sided come in 32, 64,
128, 256MB.

3.6 Central Processing Unit (CPU)
The motherboard provides a ZIF Socket 370. The CPU that came with the mother-
board 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. Without 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 (or corner with gold arrow) 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. With 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 processor or else
boot-up may not be possible. Socket 370 processors provide internal thermal sens-
ing so that a socket mounted thermal resistor is not needed.
CAUTION! Be careful not to scrape the motherboard when mounting a clamp-
style processor fan or else damage may occur to the motherboard.

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 hard-
ware 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.
5. Replace the computer system’s cover.
6. Set up the BIOS if necessary
(such as IRQ xx Used By ISA: Yes in 4.4.3 PCI Configuration)
7. Install the necessary software drivers for your expansion card.
ASUS CUWE User’s Manual

3. HARDWARE SETUP
3.7.2 Assigning IRQs for Expansion Cards
Some expansion cards need an IRQ to operate. Generally, an IRQ must be exclu-
sively 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 moth-
erboard also has MIDI enabled, another IRQ will be used, leaving 4 IRQs free.
The following table lists the default IRQ assignments for standard PC devices. Use

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.
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 Windows
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-
ever a PnP-compliant card is added to the system. For PnP cards, IRQs are assigned
automatically from those available.
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 does 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 as-
signs an IRQ to a PCI slot that has a card in it that requires an IRQ. To install a PCI
card, you need to set something called 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.
ASUS CUWE User’s Manual
29
3. HARDWARE SETUP
3.7.3 Assigning DMA Channels for ISA Cards
Some ISAcards, 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. To select a DMAchannel, see PCI/
PNP ISA DMA Resource Exclusion in 4.4.3 PCI Configuration. NOTE: The on-
board audio by default uses DMA1.
IMPORTANT: To avoid conflicts, reserve the necessary IRQs and DMAs for
legacy ISAcards (see PCI/PNPISAIRQ Resource Exclusion in 4.4.3 PCI Con-
figuration). 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 anAMR.
Main processing is done through software and controlled by the motherboard’s Intel I/
O Controller Hub (ICH). 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 must be disabled when using a primary AMR.
NOTE: An AMR is not included with this motherboard.

15) Chassis, CPU, &PowerSupplyFanConnectors(3-pinCHA_, CPU_, PWR_FAN)
These connectors support cooling fans of 350mA (4.2 Watts) or less. Orientate
the fans so that the heat sink fins allow airflow to go across the onboard heat
sink(s) instead of the expansion slots. Depending on the fan manufacturer, the
wiring and plug may be different. The red wire should be positive, while the
black should be ground. Connect the fan’s plug to the board taking into consid-
eration the polarity of the connector.
NOTE: The “Rotation” signal is to be used only by a specially designed fan with
rotation signal. The Rotations per Minute (RPM) can be monitored usingASUS PC
Probe Utility or Intel LDCM Utility (see 6. SOFTWARE REFERENCE).
WARNING! The CPU and/or motherboard will overheat if there is no airflow
across the CPU and onboard heatsinks. Damage may occur to the motherboard
and/or the CPU fan if these pins are incorrectly used. These are not jumpers,
do not place jumper caps over these pins.

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.

A Note about Passwords
The BIOS Setup program allows you to specify passwords in the Main menu. The
passwords control access to the BIOS during system startup. The passwords are not
case sensitive. In other words, it makes no difference whether you enter a password
using upper or lowercase letters.
The BIOS Setup program allows you to specify two separate passwords: a Supervisor
password and a User password. When disabled, anyone may access all BIOS Setup
program functions. When enabled, the Supervisor password is required for entering
the BIOS Setup program and having full access to all configuration fields.
