PC100 SDRAM modules operate at 100MHz with a peak bandwidth of 0.8GB/s,
MCH dual channel Rambus DRAMs can operate at up to 400 MHz with a peak
bandwidth of 3.2GB/s.

• 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 W indows
98/2000/Millenium, 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 have to wait for a long time for system bootup.

• New Compliancy: Both the BIOS and hardware levels of the motherboard meet

the stringent requirements for PC 99 certification. 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/NT and later. Color-coded connectors and descrip­tive icons make identification easy as required by PC 99.

2.1.3 Intelligence

• Auto CPU Throttling Function: Incorporated into this motherboard is a new

technology to enable Pentium 4 processors auto throttling function. When auto
throttling is enabled, the CPU with throttle down to 50% of its duty cycle when
the CPU temperature reaches the threshold and return to 100% of its duty cycle
when temperature lowers to normal level. This function ensures the best
performance and reliability.

• Fan Status Monitoring and Alarm: To prevent system overheat and system

damage, the CPU, PCI, and MAIN fans can be monitored for RPM and failure.
All the fans are set for its normal RPM range and alarm thresholds.

• T emperature Monitoring and Alert: T o prevent system overheat and system dam-

age, 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.

Intelligence

2. FEATURES

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

Millenium, and W indows NT/2000, require much more memory and hard drive
space to present enormous user interfaces and run large applications. The onboard
hardware ASUS ASIC in conjunction with either the bundled ASUS PC Probe
or Intel LDCM 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 BIOS, the power button can be defined
as the “Stand by” (a.k.a. Suspend or Sleep) button or as the Soft-Off (see ATX
Power / Soft-Off Switch Lead in 3.8 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): Message LEDs now act as infor-
mation providers. Through the way a particular LED illuminates, the user can
determine if a message has been received from a fax/modem. A simple glimpse
provides useful information to the user. This function requires ACPI OS and
driver support.

• 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 click.

2) USB Device Wake Up (USBPWR)

This allows you to disable or enable the USB device wake up function. Set this
jumper to Enable if you wish to use your USB devices to wake up your computer .
This feature requires an ATX 12V power supply that can supply at least 2A on the
+5VSB lead. The default is set to Disable because not all computers have the
appropriate ATX power supply. Your computer will not power ON if you set this
to Enable and do not have the appropriate ATX power supply.

NOTES

1. This jumper must be set in conjunction with Wake On USB Device in 4.5.1

IMPORTANT

1. The memory configuration of channel A (RIMMA1 and RIMMA2) and chan­nel B (RIMMB1 and RIMMB2) must be identical (see below).

2. C-RIMMs (Continuity RIMM) must be used to complete the sockets that are
not populated by RDRAMs. A C-RIMM is necessary to avoid breaking the
signal lines, which are a serial connection in a Rambus interface, such as
used in this motherboard. This assures the electrical integrity of a Rambus
interface.

3. When C-RIMMs are required, it is recommended that they be inserted into
RIMMA2 and RIMMB2.

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 (see 3.3 Hardware Setup Proce-

dure for more information).

3.7.1 Expansion Card Installation Procedure

1. Read the documentation for your expansion card and make any necessary hard­ware 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 PNP AND PCI SETUP)

7. Install the necessary software drivers for your expansion card.

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 moth-

erboard also has MIDI enabled, another IRQ will be used, leaving 4 IRQs free.

3.8 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 cables must be less than 46 cm (18 in.), with the
second drive connector no more than 15 cm (6 in.) from the first connector.

1) PS/2 Mouse Connector (Green 6-pin PS2KBMS)

The system will direct IRQ12 to the PS/2 mouse if one is detected. If one is not
detected, expansion cards can use IRQ12. See PS/2 Mouse Function Control
in 4.4 Advanced Menu.

PS/2 Mouse (6-pin Female)

2) PS/2 Keyboard Connector (Purple 6-pin PS2KBMS)

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 monitored using a utility such
as ASUS PC Probe or Intel LDCM.

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.

This lead is for a chassis designed for chassis intrusion detection. After-market
toggle switches may also be installed to the chassis panel or on any removable
components. Two wires should be available from the chassis to connect to this
lead. When any chassis component is removed, the contact should open and the
motherboard will record a chassis intrusion event. The event can then be pro­cessed by software such as LDCM. If the chassis intrusion lead is not used, a

jumper cap must be placed over the pins to close the circuit.

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 W riter
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 floppy
disk. DO NOT copy AUTOEXEC.BAT & CONFIG.SYS to the disk.

2. Type COPY E:\AFLASH\AFLASH.EXE A:\ (assuming E 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.

Updating BIOS

4. BIOS SETUP

IMPORTANT! If “unknown” is displayed 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.

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. Care­less updating can result in your motherboard having more problems!

4. BIOS SETUP

Updating BIOS

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 Includ-
ing 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>.

ASUS P4T User’s Manual46

4. BIOS SETUP

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 necessary. 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 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 screens and descriptions are for reference purposes only and may not reflect
your BIOS screens exactly.

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.

Forgot the Password?

If you forgot the password, you can clear the password by erasing the CMOS Real
Time Clock (RTC) RAM. The RAM data containing the password information is
powered by the onboard button cell battery. To erase the RTC RAM: (1) Unplug
your computer, (2) Short the solder points, (3) Turn ON your computer, (4) Hold
down <Delete> during bootup and enter BIOS setup to re-enter user preferences.
