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 PC133-com-

pliant Synchronous Dynamic Random Access Memory (SDRAM), which increases
the data transfer rate to 1066MB/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
98/2000/Millenium, must be used.

• 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. 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: Today’s operating systems, such as Windows 98/

Millenium, W indows NT/2000, 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 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.

Intelligence

2. FEATURES

• Peripheral Power Up: Keyboard power up can be enabled or disabled through
BIOS setup to allow the computer to be powered ON using your keyboard.

grated 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.

3. HARDWARE SETUP

1) JumperFree™ Mode (JEN)

3.5 System Memory (DIMM)

NOTE: No hardware or BIOS setup is required after adding or removing memory.
This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are

available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Ac-
cess Memory (SDRAM) of 16, 32, 64, 128MB, 256 or 512MB. to form a memory size
between 16MB and 1.5GB. One side (with memory chips) of the DIMM takes up one
row on the motherboard. This motherboard also supports NEC’s V irtual Channel (VC)
SDRAMs.

To use the chipset’s Error Checking and Correction (ECC) feature, you must use a
DIMM with 9 chips per side (standard 8 chips/side + 1 ECC chip).

Memory speed setup is recommended through Configure SDRAM T iming by SPD
(see 4.4.2 Advanced Chipset Setup).

3.5.2 DIMM Memory Installation

Insert the module(s) as shown. Because the number of pins are different on either
side of the breaks, the module will only fit in the orientation shown. DIMM mod­ules are longer and have different pin contact on each side and therefore have a
higher pin density. SIMM modules have the same pin contact on both sides.

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. After the CPU is , 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.

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.

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.

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