and positional capability. Includes complete online help to guide you through
the audio software.

• Space Savings! Digital Flat Panel (DFP) Interface gives a direct digital connec-
tion for connecting a digital flat panel (analog flat panel must be connected to
the VGA-out connector) to your PC. This interface transmits sharp, bright im­ages by eliminating digital-to-analog and analog-to-digital conversions, which
can accumulate noise and degrade image quality.

• No Messy Wires! Integrated Consumer IR and Standard IR supports an op-
tional remote control package for wireless interfacing with external peripherals,

personal gadgets, or an optional remote controller.

ASUS CUWE-RM User’s Manual 9

2. FEATURES

Performance

2. FEATURES

2.1.3 Performance

• UltraPerformance! Onboard IDE Bus Master controller with two connectors

that support four IDE devices in two channels. Supports UltraDMA/66, UltraDMA/
33 (IDE DMA Mode 2), PIO Modes 3 & 4, and supports Enhanced IDE devices,
such as Tape Backup, CD-ROM, CD-R/RW, and LS-120 drives.

• Double or Quadruple the IDE T ransfer Speed! IDE transfers using UltraDMA/

33 Bus Master IDE can handle rates up to 33MB/s and up to 66MB/s using
UltraDMA/66 technology. The best of all is that these new technology is com­patible with existing ATA-2 IDE specifications so there is no need to upgrade
current IDE devices or cables.

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

ter buses to memory to CPU.

• SDRAM Optimized Performance! ASUS smart series motherboards support the

new generation memory , Synchronous Dynamic Random Access Memory (SDRAM),
which increases the data transfer rate to 800MB/s max using PC100-compliant
SDRAM.

• ACPI Ready! ACPI (Advanced Configuration and Power Interface) is also imple-

mented on all ASUS smart series motherboards. ACPI provides more Energy
Saving Features for future operating systems (OS) supporting 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.

• Suspend and Go! Suspend-To-RAM (STR) provides maximum power savings

as an alternative to leaving the computer ON and QuickStart™ so that you do
not fall asleep waiting for system bootup. (STR requires OS support)

• New Compliancy! Both the BIOS and hardware levels of the motherboard 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 . Color­coded connectors and descriptive icons make identification easy as required by
PC’99.

• Highest Audio Quality! AC’97 DAC/ADC built into the audio codec reduces noise

to improve audio quality and performance for a SNR (signal to noise ratio) of
+90dB. These features greatly improve voice synthesis and recognition.

• Extreme Graphics! The integrated motion compensation allows for smooth

MPEG1 or MPEG2 video playback. Fast 3D graphics engine allows for an ex­citing gameplay experience.

10 ASUS CUWE-RM User’s Manual

2. FEATURES

2.1.4 Intelligence

• 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 the fans are set for its normal RPM range and alarm thresholds.

• Temperature Monitoring and Alert! To prevent system overheat and system

damage, this motherboard supports processor thermal sensing and auto-protec­tion.

• Voltage Monitoring and Alert! System voltage levels are monitored to ensure

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 Resources Alert! T oday’s operating systems such as W indows 98, W in-

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 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.

Intelligence

2. FEATURES

• 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 infor­mation 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
keyboard or mouse.

3.3 Hardware Setup Procedure

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

• Check Motherboard Settings

• Install Memory Modules

• Install the Central Processing Unit (CPU)

• Install Expansion Cards

• Connect Ribbon Cables, Panel Wires, and Power Supply

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.

WARNING! 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.

8) CPU External Frequency Setting (DSW)

This option tells the clock generator what frequency to send to the CPU, DRAM,
and the PCI bus. This allows the selection of the CPU’s External frequency . The
CPU External Frequency multiplied by the Frequency Multiple equals the CPU’s
Internal frequency (the advertised CPU speed). NOTE: Y ou may set the memory
speed independently from the CPU External Frequency. Depending on your
memory type, select the appropriate “SDRAM” speed along with the appropri­ate “CPU” speed.
IMPORTANT: When JumperFree mode is enabled, use BIOS setup in place of
these switches (see CPU Speed in 4.4 Advanced Menu). Only selected switches
are illustrated, see the next page for a complete frequency listing.
NOTE: In JumperFree mode, all DIP switches (DSW) must be set to OFF.

NOTE: Frequency Multiple settings are not available here because usually
Socket 370 processors have locked Frequency Multiples. If your Socket 370
processor does not have a locked Frequency Multiple, you must use CPU
Core:Bus Freq. Multiple in 4.4 Advanced Menu of the BIOS setup to set the
Frequency Multiple. If the Frequency Multiple is locked, setting the Frequency
Multiple in BIOS setup will have no effect.

WARNING! CPU frequencies above 66MHz exceed the specifications for cur-

rent Celeron processors and are not guaranteed to be stable. For Coppermine pro­cessors, CPU frequencies other than the recommended bus frequencies are not
guaranteed to be stable. Premature wearing of the processor may result when
overclocking. Be sure that the DIMM you use can handle the specified SDRAM
MHz or else bootup will not be possible.

3.5 System Memory (DIMM)

NOTE: No hardware or BIOS setup is required after adding or removing memory.
This motherboard uses only Dual Inline Memory Modules (DIMMs). S ockets are

available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Ac-
cess Memory (SDRAM) of 16, 32, 64, 128MB, or 256MB (512MB maximum sys­tem memory using 128Mb technology).

This chipset does not support ECC. However, ECC memory modules may still be
used, but the ECC function will not be available.

Memory speed setup is recommended through SDRAM Configuration in 4.4.1

Chip Configuration.

NOTE: At the time this User’s Manual was written, 256MB DIMMs are only avail-

able as Double-Sided registered memory. Using 2x2x2 SDRAM can greatly im­prove the onboard graphics’ performance.

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.

3.5.2 Memory Installation

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. DIMM mod­ules are longer and have different pin contact on each side and therefore have a
higher pin density. SIMMs have the same pin contact on both sides.

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 (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. 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-

style processor fan or else damage may occur to the motherboard.

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.

The following table lists the default IRQ assignments for standard PC devices. Use

3.7.3 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 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.
