2. FEATURES
2.1.2 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, anACPI-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’98 Compliant: Both the BIOS and hardware levels of ASUS smart series
motherboards meet PC’98 compliancy.The 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
Windows95/98/NT.
•Symbios SCSI BIOS: Supports optional ASUS SCSI controller cards through
the onboard SYMBIOS firmware.
2.1.3 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/HSDRAM Optimized Performance: Supports the new generation
memory, NEC’s Virtual Channel (VC) SDRAMs (Synchronous Dynamic Ran-
dom Access Memory) or Enhanced Memory System’s High-speed DRAMs
(HSDRAMs) for higher system performance at minimal cost premium.

2. FEATURES
Intelligence
2.1.4 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.
•PS/2Keyboard/MousePower Up:Keyboard/Mouse Power Up can be enabled
or disabled to allow the computer to be powered on by either pressing the space
bar, Ctrl-Esc, or Power keys (see 4.5.1 Power Up Control).
•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 theASUS S370-133
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.

3. CPU Bus Frequency Selection (U12–Switches 7, 8, 9, 10)
This option tells the clock generator what frequency to send to the CPU, DRAM, and
PCI bus. This allows the selection of the CPU’s External frequency (or BUS Clock).
The BUS Clock multiplied by the BUS Multiple equals the CPU’s Internal frequency
(the advertised CPU speed).
NOTE: In JumperFree mode, all dip switches must be set to OFF.

NOTE: Overclocking your processor is not recommended. It may result in a slower
speed. Voltage Regulator Output Selection (VID) is not required for Pentium III/II
processors because they send signals directly to the onboard power regulator.
WARNING! Frequencies above 133MHz exceed the specifications for the on-
board chipset and are not guaranteed to be stable.

3.5 System Memory (DIMM)
This motherboard uses only Dual Inline Memory Modules (DIMMs). Four sockets
are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random
Access Memory (SDRAM) of 8, 16, 32, 64, 128, 256, or 512MB to form a memory
size between 8MB to 2GB. One side (with memory chips) of the DIMM takes up one
row on the motherboard. This motherboard also supports NEC’s Virtual Channel
(VC) SDRAMs and Enhanced MemorySystem’s High-speed DRAMs (HSDRAMs).
Memory speed setup is recommended through 4.4.1 Chip Configuration.
IMPORTANT (see General DIMM Notes below for more)
•SDRAMs used must be compatible with the current Intel PC133 SDRAM
specification.
•DO NOT attempt to mix registered SDRAMs with VC SDRAMs.
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, 256, 512MB x1
Socket 2 (Rows 2&3) SDRAM 8, 16, 32, 64, 128, 256, 512MB x1
Socket 3 (Rows 4&5) SDRAM 8, 16, 32, 64, 128, 256, 512MB x1
Socket 4 (Rows 6&7) SDRAM 8, 16, 32, 64, 128, 256, 512MB x1
Total System Memory (Max 2GB) =
General DIMM Notes
•DIMMs that have more than 18 chips are not supported on this motherboard.
•For the system bus to operate at 100MHz, use only PC100- or PC133-compliant
DIMMs;forthesystembustooperateat133MHz,usePC133-compliantDIMMs.
•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, 64,128, or 256MB; double-sided come in 32,
64, 128, 256, or 512MB.
