•Around-the-Clock Intrusion Detection: Chassis intrusion circuitry can log
chassis open events into LDCM. The onboard battery supports detection 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, such as CPU and systerm voltages, temperatures, and fan
status through the onboard hardware ASUS ASIC and the bundled ASUS PC
Probe or Intel LDCM software.
•CNR Support: A Communication and Networking Riser (CNR) slot provides
an interface to support very affordable multichannel audio,V.90 analog modem,
Home PNA, 10/100 Ethernet networking, and USB hub.
•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 98/2000/Millenium
compatibility,built-infirmware-based virus protection, andautodetection of most
devices for virtually automatic setup.
•Smart BIOS: The firmware hub gives a new easy-to-use interface which pro-
videsmorecontrolandprotectionoverthemotherboard.ProvidesVcore and CPU/
SDRAM frequency adjustments, boot block write protection, and HD/SCSI/MO/
ZIP/CD/Floppybootselection. Hardware random number generator supportsnew
security software for data protection and secured Internet transactions.
•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.
•SMBus:Features the System Management Businterface,which is used to physi-
cally transport commands and information between SMBus devices.

2.1.2 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.
•Smart Card Reader Compatible: PC/SC compliant Smart Card Reader
connectivity.
2.1.3 Performance
•UltraPerformance:OnboardIDEBusMastercontrollerwithtwoconnectorsthat
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,andTapeBackupdrives.
•Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI
master 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.

Intelligence
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.
•Temperature Monitoring and Alert: To prevent system overheat and system
damage,this motherboard supports processor thermalsensing 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 98/
Millenium,Windows NT/2000,require much morememory and harddrive space
to present enormous user interfaces and run large applications. The onboard
hardware ASUS 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.

3.4 Motherboard Settings
WARNING! Computer motherboards and expansion cards contain delicate
Integrated Circuit (IC) chips. To protect them against damage from static
electricity, take precautions whenever working on the computer.
1. Unplug the computer when working on the inside.
2. Use a grounded wrist strap before handling computer components. If you do
nothave one, touch both hands to a safelygrounded object or toa 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. 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 plugging in or
removing the ATX power connector on the motherboard.

2) USB Device Wake Up (USWR01, USWR56)
These jumpers disable or enable the USB device wake up function. Set these
jumpers to Enable to wake up the computer with USB devices. This
feature requires an ATX power supply that can supply at least 2A on the +5VSB
lead. The default is set to Disable because not all computers have the appropriate
ATX power supply. The computer will not power ON if the jumper is set to
Enable and if the wrong ATX power supply is connected. NOTE: This jumper
must be set in conjunction with Wake On USB for STR State in 4.5.1 Power Up
Control.
NOTES
1. For enabling Wakeup during STR/STD/Soft off functions, set to Enable.
2. The total current consumed must NOT exceed the power supply capability
(+5VSB) whether under normal working conditions or in the sleep mode.

4) Keyboard Power Up (KBPWR)
This jumper disables or enables the keyboard power up function. Set this jumper
to Enable if you wish the keyboard (by pressing <Spacebar>) to power up the
computer. This feature requires an ATX power supply that can supply at least
300mA on the +5VSB lead. The default is set to Disable because not all
computers have the appropriateATX power supply. The computer will not power
ON if you set this to Enable and if the wrong ATX power supply is connected.
NOTE: This jumper must be set in conjunction with Wake On PS2 KB/PS2
