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.

2. FEATURES

Performance

• 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 and processor.

• SDRAM Optimized Performance: This motherboard supports PC100-com-

pliant Synchronous Dynamic Random Access Memory (SDRAM), which increases
the data transfer rate to 800MB/s max

• 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.

• 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 W indows 95/98/NT . Color-coded connectors and descriptive icons
make identification easy as required by PC 99.

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.

• 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.

• System Resources Alert: T oday’s operating systems, such as Windows 98, Win-

dows NT , and OS/2, 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 25) A TX
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.

Intelligence

2. FEATURES

• 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.

3.3 Hardware Setup Procedure

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

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
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. The onboard LED when
lit acts as a reminder that the system is in suspend or soft-off mode and not
powered OFF.

3.6 Central Processing Unit (CPU)

The motherboard provides a ZIF Socket 370. The CPU that came with the mother­board should have a fan attached to it to prevent overheating. If this is not the case,
then purchase a fan before you turn on your system.

WARNING! Be sure that there is sufficient air circulation across the processor’s

heatsink by regularly checking that your CPU fan is working. W ithout sufficient
circulation, the processor could overheat and damage both the processor and the
motherboard. You may install an auxiliary fan, if necessary.

To install a CPU, first turn off your system and remove its cover. Locate the ZIF
socket and open it by first pulling the lever sideways away from the socket then
upwards to a 90-degree angle. Insert the CPU with the correct orientation as shown.
The notched corner should point towards the end of the lever . Because the CPU has
a corner pin for two of the four corners, the CPU will only fit in the orientation as
shown. The picture is for reference only; you should have a CPU fan that covers the
face of the CPU. With the added weight of the CPU fan, no force is required to
insert the CPU. Once completely inserted, close the socket’s lever while holding
down the CPU. Next, install an Intel recommended fan heatsink. Locate the CPU
fan connector (see 3.1 Motherboard Layout or 3.8 Connectors) and connect the
CPU fan cable to it.

3. H/W SETUP

NOTE: Do not forget to set the correct Bus Frequency and Multiple (frequency
multiple setting is available only on unlocked processors) for your Socket 370 pro­cessor or else boot-up may not be possible. Socket 370 processors provide internal
thermal sensing so that a socket mounted thermal resistor is not needed.

CAUTION! Be careful not to scrape the motherboard when mounting a clamp-

style processor fan or else damage may occur to the motherboard.

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.

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.

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 will 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.

ASUS CUC2000 User’s Manual 29

Both ISA and PCI expansion cards may require IRQs. System IRQs are available to
cards installed in the ISA expansion bus first, then any remaining IRQs are available
to PCI cards. Currently, there are two types of ISA cards.

The original ISA expansion card design, now referred to as legacy ISA cards, re­quires that you configure the card’s jumpers manually and then install it in any
available slot on the ISA bus. To see a map of your used and free IRQs in W indows
98, the Control Panel icon in My Computer, contains a System icon, which gives
you a Device Manager tab. Double-clicking on a specific hardware device gives
you the Resources tab which shows the Interrupt number and address. Double-click
Computer to see all the interrupts and addresses for your system. Make sure that no
two devices use the same IRQ or your computer will experience problems when
those two devices are in use at the same time.

To simplify this process, this motherboard complies with the Plug and Play (PNP)
specification which was developed to allow automatic system configuration when-

3. H/W SETUP

DMA Channels

ever a PNP-compliant card is added to the system. For PNP cards, IRQs are as­signed automatically from those available.

3. HARDWARE SETUP

If the system has both legacy and PNP ISA cards installed, IRQs are
assigned to PNP cards from those not used by legacy cards. The PCI and PNP con­figuration of the BIOS setup utility can be used to indicate which IRQs are being
used by legacy cards. For older legacy cards that do not work with the BIOS, you
can contact your vendor for an ISA Configuration Utility.

An IRQ number is automatically assigned to PCI expansion cards after those used
by legacy and PNP ISA cards. In the PCI bus design, the BIOS automatically as­signs an IRQ to PCI cards that require an IRQ. To install a PCI card, you need to set
the INT (interrupt) assignment. Since all the PCI slots on this motherboard use an
INTA #, be sure that the jumpers on your PCI cards are set to INT A.

Assigning DMA Channels for ISA Cards

Some ISA cards, both legacy and PNP , may also need to use a DMA (Direct Memory
Access) channel. DMA assignments for this motherboard are handled the same way
as the IRQ assignment process described earlier. You can select a DMA channel in
the PCI and PNP configuration section of the BIOS Setup utility.

IMPORTANT: To avoid conflicts, reserve the necessary IRQs and DMAs for

legacy ISA cards (see 4.4.3 PCI Configuration. Choose Yes in IRQ xx Used By
ISA and DMA x Used By ISA for those IRQs and DMAs you want to reserve).

3.7.4 Audio Modem Riser (AMR) Slot

This connector supports a specially designed audio and/or modem card called an AMR.
Main processing is done through software and controlled by the motherboard’s sys-
tem chipset. This provides an upgradeable audio and/or modem solution at an incred­ibly low cost. There are two types of AMR, one defined as primary and another de­fined as secondary. This motherboard uses the primary channel so that a secondary
AMR can coexist without the need to disable the onboard CODEC. The motherboard’s
onboard CODEC (optional) must be disabled when using a primary AMR.

NOTE: An AMR is not included with this motherboard.

sion module to be installed (see 7. APPENDIX). If the chassis intrusion lead is
not used, a jumper cap must be placed over the pins to close the circuit.

9) Primary (Blue) / Secondary IDE Connectors (40-1 pin IDE1/IDE2)

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.

IMPORT ANT: UltraDMA/66 IDE devices must use a 40-pin 80-conductor IDE cable.

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.

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.

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.

case sensitive. In other words, it makes no difference whether you enter a password
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, 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) Remove the battery from the motherboard.
(3) Wait at least 30 seconds and replace the battery.
(4) Short the solder points (see below for location).
