2.1.3 Special Features
•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 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 must be used.
•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’99 Compliant: Both the BIOS and hardware levels of ASUS smart series
motherboards meet PC’99 compliancy. The new PC’99 requirements for sys-
tems and components are based on the following high-level goals: Support for
Plug and Play compatibility and power management for configuring and man-
aging all system components, and 32-bit device drivers and installation proce-
duresforWindows95/98/NT. Color-coded connectors anddescriptive icons make
identification easy as required by PC’99.
•Symbios SCSI BIOS: Supports optional ASUS SCSI controller cards through
the onboard SYMBIOS firmware.
2.1.4 Performance Features
•Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-
ter busses to the memory and processor.
•High-Speed Data Transfer Interface: IDE transfers using UltraDMA/33 Bus
Master IDE can handle rates up to 33MB/s. This motherboard with its chipset
and support for UltraDMA/66 doubles the UltraDMA/33 burst transfer rate to
66.6MB/s. UltraDMA/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. (UltraDMA/66 requires a 40-pin
80-conductor cable to be enabled and/or for UltraDMA Mode 4.)
•VCM/SDRAMOptimizedPerformance:Thismotherboard supports a new gen-
eration memory, NEC’s 64Mb Virtual Channel Memory (VCM) Synchronous
Dynamic RandomAccess Memory (SDRAM), which is compatible to the indus-
try standard SDRAM. The VCM’s core design provides up to 50% higher
SDRAM speed at reduced power consumption of about 30%. This motherboard
also supports standard SDRAM, which increases the data transfer rate (1.064GB/s
max using PC133-compliant SDRAMs and 800MB/s max using PC100-compli-
ant SDRAMs).

Intelligence
2.1.5 Intelligence
•Auto Fan Off: The system fans will power 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.
•Dual Function Power Button: Pushing the power button for less than 4 sec-
onds 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, power supply, and system fans can be monitored for RPM
and failure. All fans are set for its normal RPM range and alarm thresholds.
•Message LED (requiresACPI OS support): Turbo LEDs now act as informa-
tion providers. Through the way a particular LED illuminates, the user can de-
termine if there are messages waiting in the mailbox.Asimple glimpse provides
useful information to the user.
•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!
•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 will give the user information on managing
their limited resources more efficiently.
•Temperature Monitoring and Alert: CPU temperature is monitored by the
ASUSASIC through the CPU’s internal thermal diode (on Pentium III, Pentium
II (Deschutes), and PPGA370 Celeron in conjunction with the ASUS S370 Se-
ries CPU card) 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.

WARNING! Computer motherboards and expansion cards contain very delicate
Integrated Circuit (IC) chips. To protect them against damage from static electric-
ity, 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 re-
moving 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.

2) I/O Voltage Setting (VIO)
VIO allows you to select the voltage supplied to the DRAM, chipset,AGP, PCI,
and the CPU’s I/O buffer. The default voltage (3.40V) should be used unless
processor overclocking requires a higher voltage.

WARNING! Using a higher voltage may help when overclocking but may result
in the shortening of your computer component’s life. It is strongly recommended
that you leave this setting on its default.

3) 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.ThisallowstheselectionoftheCPU’sExternalfrequency(orBUSClock).
The BUS Clock multiplied by the Frequency Multiple equals the CPU’s Internal
frequency (the advertised CPU speed).
