Specifications
•PCI & ISA Expansion Slots: Provides options of five 32-bit PCI (rev 2.2) with
two 16-bit ISA expansion slots, six PCI with one ISA, and six PCI with no ISA.
All PCI slots can support Bus Master PCI cards, such as SCSI or LAN cards.
(PCI supports up to 133MB/s maximum throughput.)

lel port with EPP and ECP capabilities. UART2 can also be directed from COM2
to the Infrared Module for wireless connections.
•UltraDMA/33 Bus Master IDE: Comes with an onboard PCI Bus Master IDE con-
troller with two connectors that support four IDE devices in two channels. Supports
UltraDMA/33, PIO Modes 3 and 4, and Bus Master IDE DMA Mode 2, as well as
EnhancedIDEdevices,suchasTapeBackup, CD-ROM, CD-R/W,andLS-120drives.
•Universal Retention Mechanism: Supports a Pentium
®

aged in a Single Edge Contact Cartridge (SECC2/SECC) or a Celeron
TM
proces-
sor packaged in a Single Edge Processor Package (SEPP).
•Wake-On-LAN Connector: Supports Wake-On-LAN activity through an op-
tional ASUS PCI-L101 10/100 Fast Ethernet PCI card (see 7.1 PCI-L101 Fast
Ethernet Card) or a similar ethernet card.
•Wake-On-Ring Connector: Supports Wake-On-Ring activity through a PCI
modem card which supports a WOR connector.
•IrDA: Supports an optional infrared port module for a wireless interface.
•Onboard LED: The onboard LED will light up when there is standby power to
the PCI bus. This acts as a reminder to the user to turn OFF the power before
plugging and unplugging devices so as not to damage the motherboard, periph-
erals, and/or components.

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, an ACPI-supported OS such as Windows
98 must be used.
•Suspend and Go: Suspend-to-RAM (STR) provides maximum power savings
(averageof5watts) as an alternativetoleavingthecomputer ON andQuickStart
TM
so that you do not fall asleep waiting for system bootup (Suspend-to-RAM re-
quires OS support and does not support ISA cards; ISA cards may fail to work
coming out of STR mode).
• 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-
duresforWindows 95/98/NT.Color-coded connectors anddescriptiveiconsmake
identification easy as required by PC’99.
•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.
• Double the IDE Transfer Speed: ASUS smart series motherboards with Intel
chipsets improves IDE transfer rate using Bus Master UltraDMA/33 IDE which
can handle data transfers up to 33MB/s.
• SDRAMOptimizedPerformance:Supportsthenewgenerationmemory-Syn-
chronous Dynamic RandomAccess Memory (SDRAM) which increases the data
transfer rate to 800MB/s max using PC100-compliant SDRAM.

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/Mouse Power Up:Keyboard/Mouse Power Up can be enabled
or disabled to allow the computer to be powered on by pressing the space bar on
the keyboard or moving the mouse.
• 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, Deschutte
Pentium II, and PPGA370 Celeron in conjunction with the ASUS S370-D or
S370-L transform 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.

3.3 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 explains in detail how to change your motherboard’s function settings
through the use of switches and/or jumpers.
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.

2) CPU External Frequency Selection (DSW-Switches 7-10)
This option tells the clock generator what frequency to send to the CPU, DRAM, and
the PCI bus.ThisallowstheselectionoftheCPU’sExternal frequency(orBUSClock).
The BUS Clock multiplied by the Frequency Multiple equals the CPU’s Internal fre-
quency (the advertised CPU speed).
NOTE: In JumperFree mode, all dip switches (DSW) 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 needed for the Pentium III /
II / Celeron processor because it sends VID signals directly to the onboard power
controller.
WARNING! Frequencies above 100MHz exceed the specifications for the
onboard Intel Chipset and are not guaranteed to be stable.

This option sets the frequency multiple between the Internal frequency of the
CPU and the CPU’s External frequency. These must be set in conjunction with the
CPU Bus Frequency.
