Temperature Monitoring andAlert:To 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.
•
System Resources Alert: Today’s operating systems, such as Windows 98/
Millenium, and Windows 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” (ie.: 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.

IMPORTANT: Due to Pentium 4 CPU’s power consumption requirement, an
ATX12V power supply is recommended for this motherboard. For typical system
configurations, an ATX12V power supply that can supply at least 230W and at least
8.5A on the +12V lead is required. For heavily-loaded configurations, an ATX12V
power supply that can supply at least 300W is required.
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
WARNING! Computer motherboards and expansion cards contain very delicate
Integrated Circuit (IC) chips. To protect them against damage from static electric-
ity, 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 con-
nectors, 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.
5. Ensure that the ATX power supply is switched off before you plug in or
remove the ATX power connector on the motherboard.
WARNING! Make sure that you unplug your power supply when adding or
removing system components. Failure to do so may cause severe damage to
your motherboard, peripherals, and/or components.

ASUS P4T-CM User’s Manual
3. HARDWARE SETUP
Step 2: Mount the Heatsink:
1. Open the retaining clips. Place the
heatsink on the CPU. The heatsink
should entirely cover the CPU. Then
close and snap the clips into the locked
position plastic heatsink support braces
have built-in retaining clips, right. With
the added weight of the CPU fan and
heatsink locking brace, no extra force is
required to keep the CPU in place.
2. Connect the CPU fan cable to the fan connector. (See 3.1 Motherboard
Layout / 3.8 Connectors).
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.
WARNING! Be sure that there is sufficient air circulation across the
processor’s heatsink by regularly checking that your CPU fan is work-
ing. Without sufficient circulation, the processor could overheat and
damage both the processor and the motherboard. You may install an
auxiliary fan, if necessary.

3.6 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).
3.6.1 Expansion Card Installation Procedure
1. Read the documentation for your expansion card and make any necessary hard-
ware 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.
3.6.2 Assigning IRQs for Expansion Cards
Some expansion cards need an IRQ to operate. Generally, an IRQ must be exclu-
sively 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.

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
floppy disk. DO NOT copy AUTOEXEC.BAT & CONFIG.SYS to the
disk.
2. Type COPYD:\AFLASH\AFLASH.EXEA:\ (assuming D 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.
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.

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!
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
Including Boot Block and ESCD screen appears.
5. Type the filename of your new BIOS and the path, for example, A:\XXX-

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 per-
sists, 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 press-
ing 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 re-
flect your BIOS screens exactly.

using upper or lowercase letters. The BIOS Setup program allows you to specify two
separate passwords: a Supervisor password and a User password. When disabled, any-
one 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)Uncap
the blue jumper cap from default [1-2]; (3)Place the jumper cap onto pins [2-3] to
short the RTC CMOS registry and erase its memory; (4)Uncap the jumpers and
return the cap to the operational default position [1-2]; (5)Turn ON your computer; (6)

lent way to create professional quality video mails from PC video/audio input de-
vices and to send the mails to any recipients via VLM 3’s built-in e-mail system
through the Internet. VLM 3’s mails comprise video, sound, or snapshot informa-
tion; and thus may convey the most profound information to target audiences. It is
very convenient for mail recipients who do not need to install additional software
component in order to view VLM 3 mails.
VLM 3 works as a very applicant sales tool. It efficiently delivers profound and live
product information to your target customers without costing a fortune. VLM 3 also
helps corporate managers easily give vivid speeches and broadcast through corpo-
rate E-mail system. For personal or home users, VLM 3 easily records live video
clips allowing users to send them to friends or family members across the Internet.
VLM 3 loads video messages from PC cameras, digital camcorders, analog camcorder
via video capture cards, or from an existing AVI video clips, and captures audio
messages from PC microphones. Video and audio messages are encoded at a very
high compressed rate in a real-time mode. From data input, data conversion, to
sending video mails via Internet, or saving data to disks, the whole procedure is
done in an easy and continuous process.
VLM 3’s video clip compression rate is up to 1:900, and its playback rate is up to 30
frame per second. VLM 3 provides CIF (352 x 288 pixel) display resolution, and

7.1 Glossary
1394
1394 is the IEEE designation for a high performance serial bus tht offers data trans-
fers 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, 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.
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 in-
tegrate the components necessary to support next-generation auto-intensive PC ap-
plications such as DVD, 3-D multiplayer gaming and interactive music. The speci-
fication 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)
TheACPI specification defines a cross-platform interface designed to support many
operating systems. ACPI defines a flexible and abstract hardware interface that pro-
vides a standard way to integrate power management features throughout a PC sys-
tem, including hardware, operating system and application software. This enables
the system to automatically turn ON and OFF peripherals such as CD-ROMs, net-
work 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 com-
puter components, such as memory, disks, and the display adapter. The BIOS in-
structions 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.
ASUS P4T-CM User’s Manual
81
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 Win-
dows 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. Point-
ing 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 transac-
tions. Concurrent PCI provides increased bandwidth, reduced system latencies, im-
proves video and audio performance, and improves processing of host based appli-
cations.
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 Celeron-
PPGA), 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 oper-
ate, including Windows. 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 spe-
cific 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 them-
selves.
IDE (Integrated Drive Electronics)
IDE devices integrate the drive control circuitry directly on the drive itself, elimi-
nating the need for a separate adapter card (in the case for SCSI devices). UltraDMA/
33 IDE devices can achieve up to 33MB/Sec transfer.
82
ASUS P4T-CM User’s Manual
7. APPENDIX
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 in-
structions 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 initia-
tive 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 bottle-
neck 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 further-
more, the CPU can be treated as one of the Bus Masters. PCI 2.1 supports concur-
rent 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 unreli-
able and frustrating. Plug and play (PnP) BIOS eliminates the ISA add-on card hard-
ware 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.
RDRAM (Rambus DRAM)
Developed by Rambus, Inc., this type of memory can deliver up to 1.6GB of data
per second. RDRAM is the first interface standard that can be directly implemented
on high performance VLSI components such as, CMOS DRAMs, memory control-
lers, and graphics/video ICs.
ASUS P4T-CM User’s Manual

7. APPENDIX
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 repro-
grammed 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 de-
vices. 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 re-
quest, 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 infor-
mation 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 applica-
tions, 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 ATA/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 synchro-
nous 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.
Wake-On-LAN
Computer will automatically wake-up upon receiving a wake-up packet through a
Network interface when it is under power soft-off, suspend or sleep mode.
