status information, such as CPU and system voltages, temperatures, and fan
status through the onboard hardware ASUS ASIC and the bundled ASUS PC
Probe.
•SMBus: Features the System Management Bus interface used to physically
transport commands and information between SMBus devices.

2.1.2 Performance
•ACPI Ready: Advanced Configuration Power Interface (ACPI) provides more
Energy Saving Features for operating systems that support OS Direct Power
Management (OSPM) functionality. With these features employed in the OS,
PCs can be ready around the clock but comply with energy saving standards. To
fully utilize the ACPI benefits, use an ACPI-supported OS such as Windows
98/ME/2000.
•PC’99 Compliant: Both the BIOS and hardware levels of ASUS smart series
motherboards are PC’99 compliant. The new PC’99 requirements for systems
and components are based on the following high-level goals: Support for Plug-
n-Play compatibility and power management for configuring and managing all
system components, and 32-bit device drivers and installation procedures for
Windows 98/ME/2000. Color-coded connectors and descriptive icons make
identification easy as required by PC’99.
•High-Speed Data Transfer Interface: Support for UltraDMA/100 through the
onboard IDE bus master controller. doubles the UltraDMA/33 burst transfer
rate to 66.6MB/s. UltraDMA/100 is backward compatible with DMA/66,
DMA/33, and other existing DMA devices to save the need to upgrade current
EIDE/IDE drives. (UltraDMA/100/66 requires a 40-pin 80-conductor cable).
•Concurrent PCI:ConcurrentPCI allowsmultiple PCI transfers from PCImaster
busses to the memory and processor.
•VCM/SDRAM Optimized Performance: This motherboard supports the new
generation memory, NEC 64Mb Virtual Channel Memory (VCM) Synchronous
Dynamic RandomAccess Memory (SDRAM), that is compatible to the industry
standard SDRAM. The VCM core design provides up to 50% higher SDRAM
speed at reduced power consumption of about 30%. This motherboard also
supportsthe standard SDRAM for a the data transfer rate of up to 1.067GB/s using
PC133-compliant SDRAMs and up to 800MB/s using PC100-compliant
SDRAMs.
•Power Saving Feature: Suspend-to-RAM (STR) provides maximum power
savings as an alternative to leaving the computer ON. STR allows QuickStart™
when you get back , so you don’t have to go through the long boot process.
(NOTE:This motherboard does not support the Suspend-to-RAM (STR) feature
when you install a DIMM into the DIMM4 socket.)

Intelligence
2.1.3 Intelligence
•Auto Fan Off: The system fans powers off automatically even in sleep mode.
This function reduces both energy consumption and system noise, and is an
important feature in implementing Silent PC systems.
•DualFunctionPower 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.
•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.
•PowerLED(requiresACPI OSsupport):The power LEDindicates the system
status.
•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 anywhere.
•System Resources Alert: Today’s operating systems such as Windows 95/98/
2000/NT and OS/2, require much more memory and hard drive space to present
enormoususer interfacesand runlargeapplications. The system resource monitor
warns the user before the system resources are used up to prevent possible
application crashes. Suggestions provide the user some information on managing
their limited resources more efficiently.
•Temperature Monitoring and Alert: CPU temperature is monitored by the
ASUS ASIC through the CPU’s internal thermal diode (on Pentium III and
Celeron) to prevent system overheat and system damage.
•Voltage Monitoring andAlert: System voltage levels are monitored to ensure
stable voltage to critical motherboard components. Voltage specifications are
more critical for future processors, so monitoring is necessary to ensure proper
system configuration and management.
•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.

3.3 Hardware Setup Procedure
Before using your computer, you must complete the following steps:
1. Check motherboard settings
2. Install memory modules
3. Install the Central Processing Unit (CPU)
4. Install Expansion Cards
5. Connect Ribbon Cables, Panel Wires, and Power Supply
6. Setup the BIOS Software
3.4 Motherboard Settings
This section tells you how to change motherboard function settings through the
switches and/or jumpers.
WARNING! Computer motherboards and expansion cards contain very delicate
Integrated Circuit (IC) chips. To avoid damaging them due to static electricity,
follow these precautions whenever you work on your computer.
1. Unplug the computer when working on the internal components.
2. Use a grounded wrist strap or touch a safely grounded object or to a metal
object,suchasthe powersupplycase, beforehandlingcomputercomponents.
3. Hold components by the edges and try not to touch the IC chips on them.
4. Wheneveryou uninstallany component,placethe componentsonagrounded
antistatic pad or in the bag that came with the components.
5. Beforeyouinstallorremoveanycomponent,ensurethattheATXpower
supply is switched off or the power cord is detached from the power
supply. Failure to do so may cause severe damage to the motherboard,
peripherals, and/or components.
(TIP:When lit, the onboard LED indicates that the system is in suspend or
soft-off mode, not powered OFF.)

Motherboard Frequency Settings (DIP Switches)
The motherboard frequency is adjusted through the DIP switches. The white block
represents the switch’s position. The example below shows all the switches in the
OFF position.
1) JumperFree™Mode (JEN)
This jumper allows you to enable or disable the JumperFree™mode. The
JumperFree™mode allows processor settings to be made through the BIOS
setup (see 4.4 Advanced Menu).
Setting JEN
Enable (JumperFree) [2-3] (default)
Disable (Jumper) [1-2]
NOTE: In JumperFree™mode, set all DIP switches (DIP_SW) to OFF.

2) CPU External Frequency Selection (DIP_SW Switches 5–8)
This option tells the clock generator what frequency to send to the CPU, DRAM,
and the PCI bus. This allows the selection of the CPU’s External frequency (or
BUS Clock). The BUS Clock multiplied by the Frequency Multiple equals the
CPU’s Internal frequency (the advertised CPU speed).

WARNING!Setthe CPU frequencyonly tothe recommended settings.Frequencies
other than the recommended CPU bus frequencies are not guaranteed to be stable.
Overclocking the processor is not recommended. It may result in a slower speed.
