2.1.2 Specifications–Optional Components

The following onboard components are optional at the time of purchase:

• Onboard Audio: C-Media Audio Chip CMI8738 supporting the latest PCI 6

channel and HRTF 3D Audio sound circuitry. A software package helps setup
the multi-channel PC sound system.

®

• Promise

chip supports the ATA-100 protocol and Ultra DMA/100 data transfer speeds.
The chip also delivers reliable redundancy and stable performance to RAID
levels 0 or 1. Data “striping,” or RAID 0, improves speed performance as
I/Otasks are spread between two hard disk drives. Data “mirroring,” or RAID 1,
improves system fault tolerance as the protocol optimizes two identical hard
disks to write data to each other.

2.1.3 Performance

• UltraPerformance: Onboard IDE Bus Master controller with two connectors that

support four IDE devices in two channels. Supports UltraDMA/100, UltraDMA/
66, UltraDMA/33 (IDE DMA Mode 2), PIO Modes 3 & 4, and supports Enhanced
IDE devices:DVD-ROM, CD-ROM, CD-R/RW, LS-120, and T ape Backup drives.

chip: Available on the TUSL2, the Promise IDE controller

• 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 operating systems (OS) supporting OS Direct Power Man­agement (OSPM). W ith these features implemented in the OS, PCs can be ready
around the clock, yet satisfy all the energy saving standards. To gain all the
benefits, an ACPI-supported OS, such as Windows 98/2000/ME is required.

• 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 high-level goals: support for Plug and
Play compatibility and power management for 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.

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 ME,

Windows 2000, and OS/2, require much more memory and hard drive space to
present 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 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.

3.5 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). One side (with memory chips) of the DIMM takes up one
row on the motherboard.

Memory speed setup is recommended through SDRAM Configuration in 4.4.1

Chip Configuration.

Install memory in any combination as follows:

DIMM Location 168-pin DIMM Total Memory

Socket 1 (Rows 0&1) SDRAM 8, 16, 32, 64, 128, 256, 512MB x1
Socket 2 (Rows 2&3) SDRAM 8, 16, 32, 64, 128, 256, 512MB x1
Socket 3 (Rows 4&5) SDRAM 8, 16, 32, 64, 128, 256, 512MB x1

Total System Memory (Max 512MB) =

NOTE: Make sure the total installed memory does not exceeds 512MB. Otherwise,

the system may hang during startup.

3.5.1 General DIMM Notes

• ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the
memory of choice for best performance vs. stability.

• BIOS shows SDRAM memory on bootup screen.

• Single-sided DIMMs come in 16, 32, 64,128, 256MB; double-sided come in 32,

64, 128, 256, 512MB.

NOTE: For PC133 SDRAM to run at 133MHz, the system CPU bus must also
operate at that speed.

cause severe damage to both your motherboard and expansion cards (see 3.3
Hardware Setup Procedure for more information).

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. DRAM SIMM
modules have the same pin contacts on both sides. SDRAM DIMMs have different
pin contacts on each side and therefore have a higher pin density.

Gold Arrow

1. Locate the Socket 370 and open it by pulling
the lever gently sideways away from the socket.
Then lift the lever upwards. The socket lever
must be fully opened (90 to 100 degrees).

2. Insert the CPU with the correct orientation. The
gold arrow of the CPU must be oriented
toward the outer corner of the socket base
nearest to the tip of the lever handle.

CAUTION! The CPU fits in one orientation

and should drop easily into place. Do not force
the CPU into the socket to avoid bending the

pins. If the CPU does not fit, check its
alignment and look for bent pins.

3. Once completely inserted, press the CPU firmly and close the socket lever until it
snaps into its locked position.

4. Install an Intel fan heatsink. The heatsink should entirely cover the CPU. Care­fully attach the heatsink locking brace to the plastic clips on the socket base. W ith
the added weight of the CPU fan and heatsink locking brace, no extra force is
required to keep the CPU in place. 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.
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: a socket mounted thermal resistor is not needed.

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 moth-

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