2. FEATURES

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.

• Desktop Management Interface (DMI): Supports DMI through BIOS,

which allows hardware to communicate within a standard protocol
creating a higher level of compatibility. (Requires DMI-enabled
components.)

• Color-coded Connectors: To enhance user accessibility to system

components and to meet PC 99 compliancy, major connectors in this
motherboard are color-coded.

2. FEATURES

• 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 vital information from their computers from
anywhere in the world!

• New Compliancy: Both the BIOS and hardware levels of this mother-

board 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
Windows95/98/NT. Color-coded connectors and descriptive icons make
identification easy as required by PC 99.

• Fan Status Monitoring and Alarm: To prevent system overheat and

system damage, the CPU and system fans can be monitored for RPM
and failure. All fans are set for its normal RPM range and alarm thresh­olds.

2.1.4 Performance and Intelligence

• Enhanced ACPI & Anti-Boot V irus Protection: Programmable BIOS

(Flash EEPROM), offering enhanced ACPI for Windows 98/2000
compatibility , built-in firmware-based virus protection, and autodetection
of most devices for virtually automatic setup.

• Message LED (requires ACPI OS support): Message LEDs now act

as information 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.

• Wake-On-Ring: Supports Wake-On-Ring through a PCI modem card

or an external modem.

• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from

PCI master busses to the memory and processor.

• SMBus: The System Management Bus interface conveys commands

and information between SMBus devices.

• Onboard LED: The onboard LED will light up when there is standby

power to the motherboard. This acts as a reminder to the user to turn
OFF the power before plugging and unplugging devices so as not to
damage the motherboard, peripherals, and/or components.

• System Resources Alert: Today’s operating systems such as Windows

98/Millenium and Windows NT/2000, require much more memory and
hard drive space to accomodate 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.

• 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.

• Chassis Intrusion Detection: Supports chassis-intrusion monitoring

through the ASUS ASIC. A chassis intrusion event is kept in memory on
battery power for more protection.

• Peripheral Power Up: Keyboard or Mouse power up can be enabled or

disabled through BIOS setup to allow the computer to be powered ON
using your keyboard or mouse click.

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

seconds 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 (see PWR Button < 4 Secs in 4.5 Power Menu). When
the power button is pressed for more than 4 seconds, the system enters
the soft-off mode regardless of the BIOS setting.

2) USB Device Wake Up (USBPWR01, USBPWR23)

These allow you to disable or enable the USB device wake up function. Set these
jumpers to Enable if you wish to use your USB device s to wake up your computer.
This feature requires an ATX power supply that can supply at least 2A on the
+5VSB lead. The default is set to Disable because not all computers have the
appropriate ATX power supply . Your computer will not power ON if you set this
to Enable and do not have the appropriate A TX power supply . NOTE: This jumper
must be set in conjunction with W ake On USB for STR State in 4.5.1 Power Up

Control.
NOTES

1. For suspend to RAM function, these jumpers must be set to Enable.

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, 256MB x1
Socket 2 (Rows 2&3) SDRAM 8, 16, 32, 64, 128, 256MB x1

Total System Memory (Max 512 MB) =

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, 64,128MB; double-sided come in 32, 64,

128, 256MB.

3.5.2 Memory Installation

WARNING! Make sure that you unplug your power supply when adding or

removing memory modules or other system components. Failure to do so may
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.

3. H/W SETUP

The DIMMs must be 3.3Volt unbuffered SDRAMs. To determine the DIMM type,
check the notches on the DIMMs (see figure below).

The notches on the DIMM will shift between left, center, or right to identify the type
and also to prevent the wrong type from being inserted into the DIMM slot on the
motherboard. You must tell your retailer the correct DIMM type before purchasing.
This motherboard supports four clock signals per DIMM.

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. H/W SETUP

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 Expansion Cards

In the future, you may need to install expansion cards. The motherboard has three
PCI expansion slots to support these cards. Follow the steps in the next section
when installing expansion cards.

WARNING! Unplug the system power cord when adding or removing expan-

sion cards or other system components. Failure to do so may cause severe dam­age to both the motherboard and expansion cards.

3.7.1 Installing an Expansion Card

1. Read the documentation that comes with the expansion card and make any nec­essary hardware settings for the card before installing it.

2. Remove the system unit cover and the bracket plate on the slot you intend to use.
Keep the screw for later use.

3. Align the card connectors with the slot and press firmly until the card fits in
place.

4. Secure the card to the slot with the screw you removed earlier.

5. Replace the system cover.

6. Change the necessary BIOS settings, if any.
(see section 4.4.3 PCI Configuration to change the settings.)

7. Install the necessary software drivers for the 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 moth-

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

Onboard Audio — shared ———shared ——

IMPORTANT: If using PCI cards on shared slots, make sure that the drivers sup-

port “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.

3.7.3 Communication and Networking Riser (CNR) Slot

This connector supports specially designed network, audio, or modem riser cards.
Main processing is done through software and controlled by the motherboard’s sys-
tem chipset. This provides upgradeable network, audio, and/or modem solutions at
an incredibly low cost.

NOTE: CNR LAN is not supported if this version of the motherboard features
the Intel onboard LAN chipset.

A CNR is not included with this motherboard.
