•ASUSJumperFree™Mode: JumperFree Mode supplies precise overclocking
of CPU external (FSB) frequency in 1 MHz increments through the BIOS.
JumperFree also permits Vcore voltage adjustments through BIOS setup.
Alternatively, easy-to-use DIPswitches instead of jumpers are supplied onboard
for manual adjustment of the processor’s external frequency.
•Around-the-Clock Intrusion Detection: The onboard battery supports detec-
tion even when normal power is removed and through a new design, battery
drain is even lower than the RTC used for keeping time!
•PC Health Monitoring: Provides an easy way to examine and manage system
status information like CPU and systerm voltages, temperatures, and fan speed
status using onboard hardware: ASUS ASIC, and ASUS PC Probe software.
•CNR Support: One Communication and Networking Riser (CNR) slot
provides interfaces to support very affordable multichannel audio, V.90 analog
modem, Home PNA, 10/100 Ethernet networking, USB hub, as well as future
technologies such as xDSL.
•PCI Expansion Slots: Provides six 32-bit PCI (PCI 2.2 compliant) expansion
slots. All PCI slots can support Bus Master PCI cards, such as SCSI or LAN
cards. (PCI supports up to 133MB/s maximum throughput.)
•Low Pin Count (LPC) Multi-I/O: Provides two high-speed UART compatible
serial ports and one parallel port with EPP and ECP capabilities. UART2 can
also be directed from COM2 to the Infrared Module for wireless connections.
•Enhanced ACPI & Anti-Boot Virus Protection: Programmable BIOS (Flash
EEPROM), offering enhanced ACPI for Windows 98/ME/2000 compatibility,
built-in firmware-based virus protection, and autodetection of most devices for
virtually automatic setup.
•Smart BIOS: 4Mbit firmware gives a new easy-to-use interface which provides
more control and protection over the motherboard. Provides Vcore and CPU/
SDRAM frequency adjustments, boot block write protection, and HD/SCSI/MO/
ZIP/CD/Floppy boot selection.
•Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-
ter busses to the memory and processor.
•Onboard LED: The onboard LED will light up when there is standby power to
the motherboard. 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,
peripherals, and/or components.
•OneTouch Management:Supports an optionalASUS iPanel, an easy to access
box with system information LED display, front I/O ports, and space reserved
for a hard disk drive. With an ASUS iPanel, you can monitor your computer
system’s vital components.
•LCD/TV Output: The Intel DVO (Digital Video Out) interface can support
either an optional LCD module for LCD output or a TV-out module for TV
output.
•SMBus:Features the System Management Businterface, which is used to physi-
cally transport commands and information between SMBus devices.

2.1.2 Specifications–Optional Components
The following onboard components are optional at the time of purchase:
•Onboard Audio: C-Media Audio Chip CMI8738 supporting the latest PCI 6
channel and HRTF 3D Audio sound circuitry. A software package helps setup
the multi-channel PC sound system.
•Promise
®
chip: Available on the TUSL2, the Promise IDE controller
chip supports the ATA-100 protocol and Ultra DMA/100 data transfer speeds.
The chip also delivers reliable redundancy and stable performance to RAID
levels 0 or 1. Data “striping,”or RAID 0, improves speed performance as
I/Otasks are spread between two hard disk drives. Data “mirroring,”or RAID 1,
improves system fault tolerance as the protocol optimizes two identical hard
disks to write data to each other.
2.1.3 Performance
•UltraPerformance:Onboard IDE BusMastercontrollerwithtwoconnectors that
support four IDE devices in two channels. Supports UltraDMA/100, UltraDMA/
66,UltraDMA/33(IDEDMA Mode 2), PIO Modes 3&4,and supports Enhanced
IDEdevices:DVD-ROM, CD-ROM, CD-R/RW, LS-120, andTape Backup drives.
•Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-
ter buses to memory and processor.
•SDRAM Optimized Performance: This motherboard supports PC133-com-
pliant Synchronous Dynamic RandomAccess Memory (SDRAM), which increases
the data transfer rate to 1066MB/s max.
•ACPIReady:ACPI(AdvancedConfigurationandPowerInterface)isalsoimple-
mented on all ASUS smart series motherboards. ACPI provides more Energy
Saving Features for operating systems (OS) supporting OS Direct Power Man-
agement (OSPM).With these features implemented in the OS, PCs can be ready
around the clock, yet satisfy all the energy saving standards. To gain all the
benefits, an ACPI-supported OS, such as Windows 98/2000/ME is required.
•Suspend and Go: Suspend-to-RAM (STR) provides maximum power savings
as an alternative to leaving the computer ON and QuickStart™so that you do
not have to wait for a long time for system bootup.
•NewCompliancy: Both the BIOS and hardware levels of the motherboard meet
the stringent requirements for PC 99 certification. The new PC 99 requirements
for systems and components are based on high-level goals: support for Plug and
Play compatibility and power management for managing all system compo-
nents, and 32-bit device drivers and installation procedures for Windows 95/98/
NT. Color-coded connectors and descriptive icons make identification easy.

2.1.4 Intelligence
•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 the fans are set for its normal RPM range and alarm thresholds.
•TemperatureMonitoringandAlert:Topreventsystemoverheatandsystemdam-
age, this motherboard supports processor thermal sensing and auto-protection.
•Voltage Monitoring andAlert: 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 ME,
Windows 2000, and OS/2, require much more memory and hard drive space to
present user interfaces and run large applications. The onboard hardwareASUS
ASIC in conjunction with either the bundled ASUS PC Probe or Intel LDCM
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.
•Dual Function Power Button: Through BIOS, the power button can be defined
as the “Stand by”(a.k.a. Suspend or Sleep) button or as the Soft-Off (see ATX
Power / Soft-Off Switch Lead in 3.8 Connectors for more information) button.
Regardless of the setting, pushing the power button for more than 4 seconds will
enter the Soft-Off mode.
•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 any information from their computers from anywhere in the world.
•Message LED (requiresACPI OS support): Message LEDs now act as infor-
mation providers. Through the way a particular LED illuminates, the user can
determine if a message has been received from a fax/modem.A simple glimpse
provides useful information to the user. This function requires ACPI OS and
driver support.
•Peripheral Power Up: Keyboard or Mouse power up can be enabled or dis-
abled through BIOS setup to allow the computer to be powered ON using your
keyboard or mouse click.

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
nothave one, touchboth of yourhands to asafely grounded objector to ametal
object, such as the power supply case.
3. Hold components by the edges and try not to touch the IC chips, leads or con-
nectors, or other components.
4. Placecomponentson a grounded antistatic pad oronthebag 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.
