•PC Health Monitoring: Provides an easy way to test and manage system 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. FEATURES
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
98/2000/Millenium.
•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 95/98/NT. 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 triples the UltraDMA/33 burst transfer rate.
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).
•ConcurrentPCI:Concurrent PCIallows multiplePCI transfers fromPCI master
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.

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 you press the power button 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(requiresACPIOSsupport):The powerLED indicatesthe system
status.
•Remote Ring-On (requires modem): This feature allows you to turn off the
computer 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 98/
Millenium and Windows NT/2000, require much more memory and hard drive
space to present enormous user interfaces and run large applications. The system
resourcemonitor warnstheuser beforethesystem resourcesareused uptoprevent
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
ASUSASIC through the thermal sensor of SocketAto 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
Complete the following steps before using your computer:
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 cables
6. Configure the BIOS parameter settings
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 powersupply case,beforehandling computer components.
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

2) CPU External Frequency Selection (FSW Switches 1–5)
This option tells the clock generator what frequency to send to the CPU, DRAM,
and the PCI and AGP buses. This allows the selection of the CPU’s External
frequency(or BUSClock).The BUSClockmultiplied bytheFrequency Multiple
equals the CPU’s Internal frequency (the advertised CPU speed).
3. HARDWARE SETUP
WARNING! Frequencies other than the recommended CPU bus frequencies are
not guaranteed to be stable.

3) Clear RTC RAM
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS.
You can clear the CMOS memory of date, time, and system setup parameters by
erasingthe CMOSRTCRAM data.The RAMdata inCMOS, thatinclude system
setup information such as system passwords, is powered by the onboard button
cell battery.
To erase the RTC RAM: (1) unplug the computer, (2) short the jumper, (3) turn
ON the computer, (4) hold down the <Del> key during the boot process and
enter BIOS setup to re-enter data.
For updated processor settings, visit the ASUS web site. See also ASUS CONTACT
INFORMATION at the beginning of this manual.

4) USB Device Wake-up Jumper (3-pin USB_UP)
This jumper allows you to enable or disable the USB device wake up feature.
Set this jumper to ENABLE if you wish to use the USB devices to wake up the
computer. This feature requires anATX power supply that can supply at least 2A
on the +5VSB lead. The default setting is DISABLE.
NOTES:
1. Before setting either of this jumper to ENABLE, make sure that you have the
appropriate power supply, otherwise the computer will not power up.
2. The total current consumed must NOT exceed the power supply capability
(+5VSB) whether under normal working conditions or in sleep mode.
