Special Features
•Enhanced ACPI and Anti-Boot Virus BIOS: Features a programmable BIOS,
offering enhanced ACPI for Windows 98 compatibility, built-in firmware-based
virus protection through Trend ChipAway Virus codes, and autodetection of most
devices for virtually automatic setup.
• 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.) (See SOFTWARE
REFERENCE.)
• Easy Installation: Incorporates BIOS that supports autodetection of hard disk
drives, PS/2 mouse, and Plug and Play devices to make the setup of hard disk
drives, expansion cards, and other devices virtually automatic.
• PC’98 Compliant: Both the BIOS and hardware levels of this motherboard meet
PC’98 compliancy.The new PC’98 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 Windows 95/98/NT.
•Symbios SCSI BIOS: Supports optional ASUS SCSI controller cards or other
Symbios SCSI cards through the onboard SYMBIOS firmware.
Performance Features
•Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-
ter busses to the memory and processor.
• High-SpeedDataTransferInterface:This motherboard with its chipsetand sup-
port for Ultra DMA/66 doubles the Ultra DMA/33 burst transfer rate to 66.6MB/s.
Ultra DMA/66 is backward compatible with both DMA/33 and DMA and with
existing DMA devices and systems so there is no need to upgrade current EIDE/
IDE drives and host systems. (Ultra DMA/66 requires a 40-pin 80-conductor cable
to be enabled and/or for Ultra DMA Mode 4.)
• SDRAM Optimized Performance: Supports the new generation memory —
Synchronous Dynamic Random Access Memory (SDRAM) — which increases
the data transfer rate to 800MB/s max using PC100-compliant SDRAM.
Intelligent Features
• Fan Status Monitoring and Alarm: To prevent system overheat and system
damage, the CPU fan and system fans are monitored for RPM and failure. Each
fan can be set for its normal RPM range and alarm thresholds.
•TemperatureMonitoringandAlert:Toavoid anyfailures triggered by extremely
high temperature, there is a heat sensor under the CPU to make sure your system
is operating at a safe heat level.

Smart Series
II. FEATURES
• AutoFanOff:The system fans will power off automatically evenin sleepmode.
This function reduces both energy consumption and system noise, and is an im-
portant feature in implementing silent PC systems.
• Dual Function PowerButton(requiresATXpowersupply): 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 setting (see Power Management Setup under BIOS SETUP). When the
power button is pressed for more than 4 seconds, the system enters the soft-off
mode regardless of the BIOS setting.
• Keyboard Power Up: Keyboard Power Up can be enabled or disabled to allow
the computer to be powered on by pressing the keyboard’s spacebar.
•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 95/98/
NT and OS/2, require much more memory and hard drive space to present enor-
mous 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 on managing the user’s limited resources more
efficiently are provided.
• CPU Slow Down: When CPU fans or system fans malfunction, the system will
deactivate the CPU Clock line to decrease CPU utilization to the speed upon
detection of system overheat. This will prevent CPU damage from system over-
heat. The CPU utilization will restore normal operations when temperature falls
below a safe level.
• Remote Ring On (requires external modem): This feature allows a computer to
be turned on remotely through an external modem. With this benefit on hand, any
user can access vital information from their computer from anywhere in the world!
• Message LED (requires ACPI-supported OS): Turbo LEDs now act as infor-
mation providers. Through the way a particular LED illuminates, the user can
determine the stage the computer is in. A simple glimpse provides useful infor-
mation to the user.

III.H/WSETUP
WARNING!Computer motherboards, baseboards and components, such asSCSI
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.
Jumpers
1. VGAInterrupt Selection (VIRQ) / 2. VGA Setting (VEN_DIS)
VIRQ allows you to set the VGA interrupt method. The default enables the

Thesejumpers tell the clock generatorwhat frequency to send tothe CPU, chipset,
and AGP. These allow the selection of the CPU’s External frequency (or BUS
Clock). The BUS Clock times the BUS Ratio equals the CPU's Internal fre-
quency (the advertised CPU speed).
7. CPU to BUS Frequency Multiple (BF0, BF1, BF2)
These jumpers set the frequency ratio between the Internal frequency of the CPU
and the Externalfrequency (called the BUS Clock) within the CPU. These must be
set together with the jumpers for CPU External (BUS) Frequency Selection.

2. System Memory (DIMM)
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 either 8, 16, 32, 64, 128MB, or 256MB to form a memory
size between 8MB and 768MB. One side (with memory chips) of the DIMM takes up
one row on the motherboard.
To utilize the chipset’s Error Checking and Correction (ECC) feature, you must use a
DIMM module with 9 chips per side (standard 8 chips/side + 1 ECC chip) and make
the proper settings through “Chipset Features Setup” in BIOS setup.
Memoryspeed setup is recommended through SDRAM Configuration under “Chipset
Features Setup” in BIOS setup.
IMPORTANT (see Notes below)
• To make using bus speeds ≥95MHz possible, SDRAMs used must be com-
patible with the current Intel PC100 SDRAM specification..
Install memory in any combination as follows:
DIMM Location 168-pin DIMM Total Memory
DIMM1 (Rows 0&1) SDRAM 8, 16, 32, 64, 128, 256MB x1
DIMM2 (Rows 2&3) SDRAM 8, 16, 32, 64, 128, 256MB x1
DIMM3 (Rows 4&5) SDRAM 8, 16, 32, 64, 128, 256MB x1
Total System Memory (Max 768MB) =
NOTES
• At the time this User’s Manual was written, 256MB DIMMs are available either as
registered memory or 128Mbit DIMMs.
•DIMMs that have more than 18 chips are not supported on this motherboard.
•Forthesystem CPUbus tooperate ≥95MHz,useonly PC100-compliantDIMMs.
When this motherboard operates at ≥95MHz, most system will not even boot if non-
compliant modules are used because of the strict timing issues involved under these
speeds. If your DIMMs are not PC100-compliant, set the CPU bus frequency to
66MHz for system stability.
• 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.
• BIOS shows SDRAM memory on bootup screen.
• Single-sided DIMMs come in 16, 32, 64,128MB; double-sided come in 32, 64, 128,
256MB.
