2. FEATURES

2.1.3 Performance

• 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 DVD-ROM, CD-ROM, CD-R/RW , LS-120, and Tape Backup drives.

• Dual Speeds: CPU frequency can operate at either 133MHz or 100MHz.

• High-Speed Data Transfer Interface: IDE transfers using UltraDMA/33 Bus

Master IDE can handle rates up to 33MB/s. This motherboard with its chipset
and support for UltraDMA/66 doubles the UltraDMA/33 burst transfer rate to

66.6MB/s. UltraDMA/66 is backward compatible with both DMA/33 and DMA
and with existing DMA devices and systems so there is no need to upgrade
current EIDE/IDE drives and host systems. (UltraDMA/66 requires a 40-pin
80-conductor cable to be enabled and/or for UltraDMA Mode 4.)

• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-

ter buses to memory to CPU.

• RDRAM Optimized Performance: This motherboard supports the new gen-

eration memory , Rambus Dynamic Random Access Memory (RDRAM). While
PC100 SDRAM modules operate at 100MHz with a peak bandwidth of 0.8GB/s,
Rambus DRAMs can operate at up to 800MHz with a peak bandwidth of 1.6GB/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 Windows
98, must be used.

• PC 99 Compliancy: Both the BIOS and hardware levels of the motherboard

meet PC 99 System Design requirements. The 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. Color-coded connectors and descriptive icons make identi­fication easy as required by PC 99.

ASUS P3C-D User’s Manual

2. FEATURES

2.1.4 Intelligence

• 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-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: T oday’s operating systems such as Windows 98, W in-

dows 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 BIOS, the power button can be defined
as the “Stand by” (a.k.a. Suspend or Sleep) button or as the Soft-Off (see 25) A TX
Power / Soft-Off 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): Message LEDs now act as infor-
mation 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 dis-
abled through BIOS setup to allow the computer to be powered ON using your
keyboard or mouse click.

• Check Motherboard Settings

• Install Memory Modules

• Install the Central Processing Unit (CPU)

• Install Expansion Cards

• Connect Ribbon Cables, Panel Wires, and Power Supply

3.4 Motherboard Settings

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

3.5 System Memory

NOTE: No hardware or BIOS setup is required after adding or removing memory.
This motherboard has three Rambus Inline Memory Module (RIMM) sockets. The

first two sockets (see Important notes for details) support Direct RDRAMs (both
ECC and non-ECC are supported) in 64, 96, 128, 192, 256, and 512MB densities for
a maximum of 1GB.

With the optional ASUS DR1 DIMM Riser, unbuffered Synchronous Dynamic Ran­dom Access Memory (SDRAM, 3.3V power level) in 64, 128 , 256, or 512MB densi­ties with Serial Presence Detect (SPD) can be used on the third socket for a maxi­mum of 1GB.

The chipset’s Error Checking and Correction (ECC) feature is available only when
using RDRAMs. ECC feature is not available when using SDRAM with an ASUS
DIMM Riser (ECC memory modules may still be used, but the ECC function will
not be available).

3.6.7 Precautions

Operating a processor at temperatures above its maximum specified operating tem­perature will shorten the processor lifetime and may cause unreliable operation. To
prevent system overheat and/or damage, it is important to have accurate tempera­ture readings of the processor core (the main source of power dissipation) for sys­tem thermal management. Included inside Pentium III, Pentium II (Deschutes), FC­PGA370 Celeron, and PPGA370 Celeron processors is a thermal sensor that is con­nected to the internal thermal diode.

Unlike other motherboards, this motherboard was designed to acquire thermal data
directly from the processor thermal diode. Therefore, the CPU temperature reported
may be higher than those from motherboards that take readings from thermal sen­sors external to the processor. This is not a cause for alarm. If, however, the BIOS
and/or your hardware monitoring program is reporting a CPU temperature above
the threshold, check the following:

1. An Intel recommended fan heatsink is used.

2. Good quality thermal interface material is used.

3. The heatsink is correctly installed onto the processor with a strong retention clip.

4. There is no visible gap between the processor die and heatsink.

The thermal interface material
should be continuous with no
through-holes or debris.

8) Primary / Secondary IDE Connectors (Two 40-1pin IDE)

These connectors support the provided UltraDMA/66 IDE hard disk ribbon cable.
Connect the cable’s blue connector to the motherboard’s primary (recommended)
or secondary IDE connector, and then connect the gray connector to your
UltraDMA/66 slave device (hard disk drive) and the black connector to your
UltraDMA/66 master device. It is recommended that non-UltraDMA/66 devices
be connected to the secondary IDE connector . If you install two hard disks, you
must configure the second drive to Slave mode by setting its jumper accord­ingly . Refer to your hard disk documentation for the jumper settings. BIOS now
supports specific device bootup (see 4.4.1 Advanced CMOS Setup). (Pin 20 is

removed to prevent inserting in the wrong orientation when using ribbon
cables with pin 20 plugged). If you have more than two UltraDMA/66 devices,

you will need to purchase another UltraDMA/66 cable.

NOTE: The hole near the blue connector on the UltraDMA/66 cable is intentional.

TIP: You may configure two hard disks to be both Masters with two ribbon

cables – one for the primary IDE connector and another for the secondary IDE
connector . You may install one operating system on an IDE drive and another on
a SCSI drive and select the boot disk through 4.4.1 Advanced CMOS 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 left­hand 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.

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.
