2.1.3 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 (requir es 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.

Intelligence

2. FEATURES

• System Resources Alert: Today’s operating systems such as Windows 95/98/

2000/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.

• 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.

This motherboard uses only Dual Inline Memory Modules (DIMMs). Four DIMM
sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic
Random Access Memory (SDRAM) of 16, 32, 64, 128, 256, 512MB , or 1GB densities
for a system memory configuration of 32MB up to 1.5GB. One side (with memory
chips) of the DIMM takes up one row on the motherboard. This motherboard also
supports NEC’s Virtual Channel SDRAMs and Enhanced Memory System’s High-

speed DRAMs.

IMPORTANT (see General DIMM Notes below for more)

• SDRAMs used must be compatible with the current Intel PC133 SDRAM
specifications.

• DO NOT attempt to mix registered SDRAMs with VCM SDRAMs.

Install memory in any combination as follows:

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.

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

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.

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 makes the system unstable or cards inoperable.

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.

IMPORTANT! If the word “unknown” appears after Flash Memory:, the

memory chip is either not programmable or is not supported by the ACPI BIOS
and therefore, cannot be programmed by the Flash Memory Writer utility.

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.

it makes no difference whether you the password using uppercase or lowercase letters.
The BIOS Setup program allows you to specify two di fferent passwords: a Supervisor

password and a User password. If you did not set a Supervisor password, anyone can
access the BIOS Setup program. If you did, the Supervisor password is required to enter
the BIOS Setup program and to gain full access to the configuration fields.

Forgot the Password?

If you forget your password, you can clear it by erasing the CMOS Real T ime Clock (RTC)
RAM. The RAM data containing the password information is powered by the onboard button
cell battery. To erase the RTC RAM: (1) Turn OFF and unplug the computer, (2) Short the
solder points on the motherboard, (3) T urn ON the computer , (4) Hold down <Delete> during

1394

1394 is the IEEE designation for the high performance serial bus at 12.5, 25 or
50MBytes/sec speeds. 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, high-speed 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.

AC’97 (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.

BIOS (Basic Input/Output System)

BIOS is a set of routines that affect how the computer transfers data between com­puter components, such as memory, disks, and the display adapter. The BIOS in­structions are built into the computer’s read-only memory. BIOS parameters can be
configured by the user through the BIOS Setup program. The BIOS can be updated
using the provided utility to copy a new BIOS file into the EEPROM.

Bit (Binary Digit)

Represents the smallest unit of data used by the computer . A bit can have one of two
values: 0 or 1.

7. APPENDIX

Boot

Boot means to start the computer operating system by loading it into system memory .
When the manual instructs you to “boot” your system (or computer), it means to
turn ON your computer . “Reboot” means to restart your computer . When using W in­dows 95 or later, selecting “Restart” from “Start | Shut Down...” will reboot your
computer.

Bus Master IDE

PIO (Programmable I/O) IDE requires that the CPU be involved in IDE access and
waiting for mechanical events. Bus master IDE transfers data to/from the memory
without interrupting the CPU. Bus master IDE driver and bus master IDE hard disk
drives are required to support bus master IDE mode.

Byte (Binary Term)

One byte is a group of eight contiguous bits. A byte is used to represent a single
alphanumeric character, punctuation mark, or other symbol.

COM Port

COM is a logical device name used by to designate the computer serial ports. Point­ing devices, modems, and infrared modules can be connected to COM ports. Each
COM port is configured to use a different IRQ and address assignment.

Concurrent PCI

Concurrent PCI maximizes system performance with simultaneous CPU, PCI and
ISA bus activities. It includes multi-transaction timing, enhanced write performance,
a passive release mechanism and support for PCI 2.1 compliant delayed transac­tions. Concurrent PCI provides increased bandwidth, reduced system latencies, im­proves video and audio performance, and improves processing of host based appli­cations.

CPU (Central Processing Unit)

The CPU, sometimes called “Processor,” actually functions as the “brain” of the
computer. It interprets and executes program commands and processes data stored
in memory. Currently, there are socket 370 (for Pentium III FC-PGA and Celeron­PPGA), socket 7 (for Pentium, AMD, Cyrix, IBM), slot 1 (for Pentium II and III),
slot 2 (for Xeon), and slot A (for AMD) processors.

Device Driver

A device driver is a special set of instructions that allows the computer’s operating
system to communicate with devices such as VGA, audio, printer, or modem.

DOS (Disk Operating System)

DOS is the foundation on which all other programs and software applications oper­ate, including W indows. DOS is responsible for allocating system resources such as
memory, CPU time, disk space, and access to peripheral devices. For this reason,
DOS constitutes the basic interface between you and your computer.

DRAM (Dynamic Random Access Memory)

There are several different types of DRAM such as, EDO DRAM (Extended Data
Output DRAM), SDRAM (Synchronous DRAM), and RDRAM (Rambus DRAM).

Flash ROM

The flash ROM is designed to be a resident program and can be updated by a spe­cific programming method. Normally , the flash ROM is used for system BIOS which
initiates hardware devices and sets up necessary parameters for the OS. Since the
contents of flash ROM can be modified, users are able to update the BIOS by them­selves.

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.

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 based on a technique called Single Instruction, Multiple
Data (SIMD), which is built into the new Intel Pentium PP/MT (P55C) and Pentium
II (Klamath) CPU as well as other x86-compatible microprocessors. The MMX in­structions are designed to accelerate multimedia and communications applications,
such as 3D video, 3D sound, video conference.

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

SDRAM is Intel's goal is to ensure that memory subsystems continue to support
evolving platform requirements and to assure that memory does not become a bottle­neck to system performance. It is especially important to ensure that the PC memory
roadmap evolves together with the performance roadmaps for the processors, I/O
and graphics.

PCI Bus (Peripheral Component Interconnect Local Bus)

PCI bus is a specification that defines a 32-bit data bus interface. PCI is a standard
widely used by expansion card manufacturers.

PCI Bus Master

The PCI Bus Master can perform data transfer without local CPU help and further­more, 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.

Plug and Play BIOS

The ISA bus architecture requires the allocation of memory and I/O address, DMA
channels and interrupt levels among multiple ISA cards. However, configuration of
ISA cards is typically done with jumpers that change the decode maps for memory
and I/O space and steer the DMA and interrupt signals to different pins on the bus.
Further, system configuration files may need to be updated to reflect these changes.
Users typically resolve sharing conflicts by referring to documentation provided by
each manufacturer. For the average user, this configuration process can be unreli­able and frustrating. Plug and play (PnP) BIOS eliminates the ISA add-on card hard­ware conflict problem. The PnP BIOS uses a memory block to define and remember
each card's configuration, which allows the user to change the card's IRQs and DMA
in BIOS either automatically or manually.

POST (Power On Self Test)

When you turn ON the computer, it will first run through the POST, a series of
software-controlled diagnostic tests. The POST checks system memory , the mother ­board circuitry, the display, the keyboard, the diskette drive, and other I/O devices.

PS/2 Port

PS/2 ports are based on IBM Micro Channel Architecture. This type of architecture
transfers data through a 16-bit or 32-bit bus. A PS/2 mouse and/or keyboard may be
used on ATX motherboards.

ROM (Read Only Memory)

ROM is nonvolatile memory used to store permanent programs (called firmware)
used in certain computer components. Flash ROM (or EEPROM) can be repro­grammed with new programs (or BIOS).

SCSI (Small Computer System Interface)

High speed multi-threaded I/O interface defined by the X3T9.2 committee of the
American National Standards Institute (ANSI) for connecting many peripheral de­vices. The standard started from 10MBytes/sec to 160MBytes/sec available today.

SDRAM (Synchronous DRAM)

The SDRAM features a fully synchronous operation referenced to a positive edge
clock whereby all operations are synchronized at a clock input which enables the
coexistence of high performance and a simple user interface. SDRAM takes memory
access away from the CPU's control; internal registers in the chips accept the re­quest, and let the CPU do something else while the data requested is assembled for
the next time the CPU talks to the memory. As they work on their own clock cycle,
the rest of the system can be clocked faster. There is a version optimized for video
cards, and main memory for motherboards.

SPD for SDRAM module

Serial Presence Detect (SPD) is most like an ID detect for SDRAM module, it using
a EEPROM component on DIMM module for storing module configuration infor­mation inside. The Serial Presence Detect function is implemented using a 2048 bit
EEPROM component. This nonvolatile storage device contains data programmed
by the DIMM manufacturer that identifies the module type and various SDRAM
organization and timing parameters.

SSE (Streaming SIMD Extensions)

A set of new instructions added to existing architectures that enables a better visual
experience with an accelerated 3D geometry pipeline and support for new applica­tions, such as real-time video encoding and speech recognition.

System Disk

A system disk contains the core file of an operating system and is used to boot up the
operating system.

UltraDMA

Ultra DMA/33 is a "synchronous DMA" protocol designed by Intel. This function is
included into Intel's PIIX4 chipset. The traditional IDE transfer only uses one edge
of the data stroke as the data transfer . Ultra DMA/33 uses both edges of data strobe
when the data is transferred. Hence, the data transfer rate is double of the PIO mode
4 or DMA mode 2 (16.6MB/s x2 = 33MB/s) on ATA-2 devices.

Ultra ATA/66, also known as Ultra DMA/66, is an extension of current Ultra ATA/
33 interface. This new high-speed interface has doubled the Ultra AT A/33 burst data
transfer rate to 66.6 Mbytes/sec and maximized disk performance under current PCI
local bus environment

USB (Universal Serial Bus)

A 4-pin serial cable bus that allows up to 127 plug and play computer peripherals
such as keyboard, mouse, joystick, scanner, printer, modem, and monitor to share a
bandwidth through a host scheduled token based protocol. This allows attaching or
detaching while the host and other peripherals are in operation. Supports synchro­nous and asynchronous transfer types over the same set of wires up to 12Mbit/sec.
USB 2.0 provides twice the transfer rate compared to USB 1.0 and competes with
the 1394 standard.
