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 (requires ACPI 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. Temperature Monitoring and Alert: CPU temperature is monitored by the ASUS ASIC through the CPUs 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. Chassis Intrusion Detection: Supports chassis-intrusion monitoring through the ASUS ASIC. A chassis intrusion event is kept in memory on battery power for more protection.

3.5.3 General DIMM Memo

DIMMs that have more than 18 chips are not supported on this motherboard. For the system CPU bus to operate at 200MHz/266MHz, use only PC1600-/ PC2100-compliant DIMMs. ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the memory of choice for best performance vs. stability. Single-sided DDR DIMMs come in 64, 128, and 256MB; double-sided come in 128, 256, and 512MB.

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.
3. H/W SETUP CPU Installation
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.

4.2 BIOS Setup Program

This motherboard supports a programmable EEPROM that you can update using the provided utility 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 pressing 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 setup screens and descriptions are for reference purposes only, and may not exactly match what you see on your screen.

7. APPENDIX

7.1 Glossary
is the IEEE designation for a high performance serial bus tht offers data transfers at 100/ 200/400 Mbps. 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 version is the integration of I/O connectivity at the back panel of personal computers using a low-cost, scalable, highspeed serial interface. The 1394 standard also provides new services such as live connect/ disconnect capability for external devices including disk drives, printers and hand-held peripherals such as scanners and cameras. 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 integrate the components necessary to support next-generation auto-intensive PC applications such as DVD, 3-D multiplayer gaming and interactive music. The specification 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) The ACPI specification defines a cross-platform interface designed to support many operating systems. ACPI defines a flexible and abstract hardware interface that provides a standard way to integrate power management features throughout a PC system, including hardware, operating system and application software. This enables the system to automatically turn ON and OFF peripherals such as CD-ROMs, network 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. Bus PCI AGP 1X AGP 2X AGP 4X Bus Frequency 33MHz 66MHz 66MHz 66MHz Bandwidth 33MHz 66MHz 133MHz 266MHz Data Transfer Rate 133MByte/sec 266MByte/sec 512MByte/sec 1024MByte/sec

A type of RAM that requires refresh cycles to prevent the loss of the data stored in it.
There are several different types of DRAM such as, EDO DRAM (Extended Data Output DRAM), SDRAM (Synchronous DRAM), and RDRAM (Rambus DRAM) and DDR DRAM, (Double-Data Rate DRAM). Flash ROM non-volatile memory device that retains its data even when power is removed. This device is similar to EPROM, but unlike EPROM which can be erased only using an ultra-violet light, flash ROM can be electrically erased. Flash ROM is normally used for system BIOS, which initiates hardware devices and sets up necessary parameters for the OS. Since the flash ROM contents can be modified, users can easily update the BIOS.
IDE (Integrated Drive Electronics) IDE devices integrate the drive control circuitry directly on the drive itself, eliminating the need for a separate adapter card (in the case for SCSI devices). UltraDMA/33 IDE devices can achieve up to 33MB/Sec transfer. I/O (Input/Output) The data transfers from the input devices like a keyboard, mouse, or scanner, to the output devices like a printer or the monitor screen. I/O Address The specific memory location for a particular device. Two devices cannot share the same I/O address space. IrDA (Infrared Data Association) An internaltional organization that creates and promotes inter-operable, low cost, infrared data interconnection standards that support a walk-up, point-to-point model. The IrDA protocol is designed to support transmission of data between two devices over short-range pointto-point infrared at speeds between 9.6Kbps and 4Mbps. ISP (Internet Service Provider) A company that provides customer access to the Internet and the World Wide Web for a fee. The ISP also provides Internet utilities and services like e-mail, newsgroup, weather reports, and a host of others. The user can connect to the ISP using a modem installed in the computer and connected to a phone line. 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 designed to accelerate multimedia and communications applications, such as 3D video, 3D sound, video conference. Modem A device that allows a computer to talk to another computer through the phone system. Network An interconnected computer system linked by telephone wires, or other means. 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 initiative 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. PC100/133 This is an industry-standard designation for memory capacity as a measure of the speed of the memory bus. New platform requirements ensure that memory does not become a bottleneck to system performance. PCI Bus (Peripheral Component Interconnect Local Bus) PCI bus is a standard specification that defines a 32-bit data bus interface. PCI Bus Master The PCI Bus Master can perform data transfer without local CPU help and the CPU can be treated as one of the Bus Masters. PCI 2.1 supports concurrent PCI operation to allow the local CPU and bus master to work simultaneously. POST (Power On Self Test) Powering on the computer initiates the POST, a series of software-controlled diagnostic tests. The POST checks system memory, the motherboard circuitry, the display, the keyboard, the diskette drive, and other I/O devices

3.5.1 General DIMM Notes
DIMMs that have more than 18 chips are not supported on this motherboard. ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the memory of choice for best performance vs. stability. BIOS shows SDRAM memory on bootup screen. Single-sided DDR DIMMs come in 64, 128, and 256MB; double-sided come in 128, 256, and 512MB.
WARNING! Be sure that the DIMMs you use can handle the specified DDR RAM MHz or else bootup will not be possible.
3.5.2 Memory Installation
26 WARNING! Make sure that you unplug your power supply when adding or removing memory modules or other system components. Failure to do so may cause severe damage to both your motherboard and expansion cards (see 3.3 Hardware Setup Procedure for more information). 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. A 184-pin DDR DRAM DIMM has a single notch slightly to the right of center.

2. Insert the CPU with the correct orientation. The notched corner of the CPU must be oriented toward the inner corner of the socket base nearest to the lever hinge. CAUTION! The CPU fits in one orientation and should drop easily into place. Do not force the CPU into the socket to avoid bending the pins. If the CPU does not fit, check its alignment and look for bent pins. 3. Once completely inserted, press the CPU firmly and close the socket lever until it snaps into its locked position. 4. Place the CPU fan and heatsink on the CPU. The heatsink should entirely cover the CPU. Carefully attach the heatsink locking brace to the plastic clips on the socket base. With the added weight of the CPU fan and heatsink locking brace, no extra force is required to keep the CPU in place. CAUTION! Take care not to scrape the motherboard surface when mounting a clamp-style processor fan, or else damage may occur. When mounting a heatsink onto your CPU, make sure that exposed CPU capacitors do not touch the heatsink, or else damage may occur! Refer to heatsink/CPU documentation. NOTE! Do not forget to set the correct Bus Frequency and Multiple (available only on unlocked processors) to avoid start-up problems.

1. Locate the Socket 462 and open it by pulling the lever gently sideways away from the socket. Then lift the lever upwards. The socket lever must be fully opened (90 to 100 degrees).

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.
3. H/W SETUP CPU Installation
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.
Standard Interrupt Assignments

3.7.4 Advanced Communication Riser (ACR) Slot
This motherboard has an Advanced Communication Riser (ACR) slot for communications and audio subsystems. The slot supports modem, audio, LAN, and Home Phoneline Networking Alliance (HPNA) or Home Networking cards. The ACR slot is backward compatible with the Audio Modem Riser (AMR) cards. IMPORTANT! The ACR slot on the motherboard shares the same expansion slot with PCI Slot 5.

3.8 Connectors

3.8.1 External Connectors
WARNING! Some pins are used for connectors or power sources. These are clearly distinguished from jumpers in the Motherboard Layout. Placing jumper caps over these connector pins will cause damage to your motherboard. IMPORTANT: Ribbon cables should always be connected with the red stripe to Pin 1 on the connectors. Pin 1 is usually on the side closest to the power connector on hard drives and CD-ROM drives, but may be on the opposite side on floppy disk drives. Check the connectors before installation because there may be exceptions. IDE ribbon cable must be less than 46 cm (18 in.), with the second drive connector no more than 15 cm (6 in.) from the first connector.

For ATX power supplies, you can press the ATX power switch after exiting or shutting down the operating system. If you use Windows 9X, click the Start button, click Shut Down, then click Shut down the computer? The power supply should turn off after Windows shuts down. NOTE: The message You can now safely turn off your computer does not appear when shutting down with ATX power supplies.

4. BIOS SETUP

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 motherboard, 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 disk. DO NOT copy AUTOEXEC.BAT and CONFIG.SYS to the disk. 2. Type COPY D:\AFLASH\AFLASH.EXE A:\ (assuming D is your CD-ROM drive) to copy AFLASH.EXE to the boot disk you created. NOTE: AFLASH works only in DOS mode. It does not work in the DOS prompt within Windows and does not work with certain memory drivers that may be loaded when you boot from the hard drive. It is recommended that you reboot using a floppy disk. 3. Reboot the 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.
