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

• Dual Speeds! CPU frequency can operate at either 66MHz or 100MHz while

system memory operates at 100MHz. This asynchronous design can optimize the

VGA performance under shared memory configuration.

• DoubleorQuadrupletheIDETransferSpeed!IDEtransfers using UltraDMA/

33 Bus Master IDE can handle rates up to 33MB/s and up to 66MB/s using

UltraDMA/66 technology. The best of all is that these new technology is com-

patible with existing ATA-2 IDE specifications so there is no need to upgrade

current IDE devices or cables.

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

ter buses to memory to CPU.

• SDRAM Optimized Performance! ASUS smart series motherboards support

the new generation memory, Synchronous Dynamic Random Access Memory

(SDRAM), which increases the data transfer rate to 800MB/s max using PC100

SDRAM.

• ACPIReady!ACPI provides more Energy Saving Features for future operating

systems (OS) supporting OS Direct Power Management (OSPM) functionality.

With 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.

•Extreme Graphics! The integrated motion compensation allows for smooth

MPEG1 or MPEG2 video playback. Fast 3D graphics engine allows for an ex-

citing gameplay experience.

• Auto Fan Off: The system fans will power off automatically even in standby

mode. This function reduces both energy consumption and system noise, and is

an important feature in implementing silent PC systems.

• Dual Function Power Button: Pushing the power button for less than 4 sec-

onds when the system is in the working state places the system into one of two

states: sleep mode or soft-off mode, depending on the BIOS or OS setting. When

the power button is pressed for more than 4 seconds, the system enters the soft-

off mode regardless of the BIOS setting.

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

nothave one, touch bothof your hands toa safely grounded objector 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. Placecomponents ona groundedantistatic pad or on the bag thatcame withthe

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.

2.5.1 General DIMM Notes

•ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the

memory of choice for best performance vs. stability.

•SDRAM chips are generally thinner with higher pin density than EDO (Extended

Data Output) chips.

•Single-sided DIMMs come in 16, 32, 64,128MB; double-sided come in 32, 64,

128, 256MB.

2.5 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, or 256MB.

This chipset does not support ECC. However, ECC memory modules may still be

used, but the ECC function will not be available.

2.5.2 DIMM 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 mod-

ules are longer and have different pin contact on each side and therefore have a

higher pin density. SIMMs have the same pin contact on both sides.

2.6 Central Processing Unit (CPU)

The motherboard provides a ZIF Socket 370. The CPU that came with the mother-

board 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.Without 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.

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

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