2.FEATURES

•Around-the-Clock Intrusion Detection! Supports chassis intrusion monitoring through the ASUS ASIC. The onboard battery supports detection even when normal power is removed and through a new design, battery drain is even lower than the RTC used for keeping time!

•Firmware Hub! Provides security and other latest power computing features.

•Monitoring for your PC’s Health! Provided ASUS PC Probe or Intel LDCM allows PC health monitoring.

•Enhanced ACPI & Anti-Boot Virus Protection! Programmable BIOS (Flash EEPROM), offering enhanced ACPI for Windows 98 compatibility, built-in firm- ware-based virus protection, and autodetection of most devices for virtually automatic setup.

•Smart BIOS! 4Mbit firmware gives a new easy-to-use interface which provides more control and protection over the motherboard. Provides Vcore and CPU/ SDRAM frequency adjustments, boot block write protection, and HD/SCSI/MO/ ZIP/CD/Floppy boot selection. Hardware random number generator supports new security software for data protection and secured Internet transactions.

2.1.2 Optional Components

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

•Smart Audio! Software Audio and Hardware AC’97 V2.1 Codec compliant, Analog Device’s 3D sound circuitry, sample rate conversion from 7kHz to 48kHz.

•Space Savings! Digital Flat Panel (DFP) Interface gives a direct digital connection 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 optional remote control package for wireless interfacing with external peripherals, personal gadgets, or an optional remote controller.

Performance	2.FEATURES

2.FEATURES

2.1.3Performance

•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 Transfer 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 optimizes system performance with concurrent PCI and CPU bus activities.

•SDRAM Optimized Performance! ASUS smart series motherboards support the new generation memory, Synchronous Dynamic RandomAccess 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 implemented on all ASUS smart series motherboards. ACPI provides more Energy Saving Features for future operating systems (OS) supporting OS Direct Power Management (OSPM) functionality. With 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 Windows 95/98/NT. Colorcoded connectors and descriptive icons make identification easy as required by PC’99.

•HighestAudio 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 CUW-RM User’s Manual

2.FEATURES

2.1.4Intelligence

•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-protec- tion.

•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! Today’s operating systems such as Windows 98, Windows 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.

•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 information 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 disabled through BIOS setup to allow the computer to be powered ON using your keyboard or mouse.

3.4Motherboard 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.

7)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: You 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.

(JumperFree Mode)

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 current 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.

3.5System Memory (DIMM)

NOTE: No hardware or BIOS setup is required after adding or removing memory.

This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM) of 16, 32, 64, 128MB, or 256MB (512MB maximum system memory using 128Mbit 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.

Install memory in any combination as follows:

Location	168-pin DIMM SDRAM		Total Memory
DIMM1	Single-Sided
(Rows 0&1)	Double-Sided	x1
DIMM2	Single-Sided (must be occupied before DIMM3)
(Rows 2&3)	Double-Sided (DIMM3 must be empty)	x1
DIMM3	Single-Sided (DIMM2 must be single-sided)
(Rows 3&2)	(Double-Sided DIMM cannot be used here!)	x1
	(must be same or half DIMM2 memory size)
	Total System Memory (Max 512MB)	=

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

3.5.2Memory 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.

3.6Central 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. 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 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 clampstyle processor fan or else damage may occur to the motherboard.

3.7.2Assigning 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 this table when configuring your system and for resolving IRQ conflicts.

Standard Interrupt Assignments

IRQ	Priority	Standard Function
0	1	System Timer
1	2	Keyboard Controller
2	N/A	Programmable Interrupt
3*	11	Communications Port (COM2)

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.
