2.1.3 Performance
•UltraPerformance:OnboardIDE Bus Mastercontrollerwithtwoconnectors that
supportfour IDEdevicesintwochannels.SupportsUltraDMA/100/66,UltraDMA/
33 (IDE DMA Mode 2), PIO Modes 3 & 4, and supports Enhanced IDE devices,
such as DVD-ROM, CD-ROM, CD-R/RW, LS-120, and Tape Backup drives.
•High-Speed Data Transfer Interface: IDE transfers using UltraDMA/66 Bus
Master IDE can handle rates up to 66.6MB/s. This motherboard with its chipset
and support for UltraDMA/100 increases the data transfer rate to 100MB/s.
UltraDMA/100 is backward compatible with DMA/66, 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/66/100 requires a 40-pin 80-
conductor cable to be enabled.)
•Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-
ter buses to memory and processor.
•RDRAM Optimized Performance: This motherboard supports the new gen-
eration memory, Rambus Dynamic RandomAccess Memory (RDRAM). While
PC100 SDRAM modules operate at 100MHz with a peak bandwidth of 0.8GB/s,
Rambus DRAMs can operate at up to 800MHz with a peak bandwidth of 1.6GB/s.
•ACPIReady:ACPI (Advanced ConfigurationandPowerInterface) is alsoimple-
mented on all ASUS smart series motherboards. ACPI provides more Energy
Saving Features for future operating systems (OS) supporting 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
98/2000/Millenium, must be used.
•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 the following high-level goals: sup-
port for Plug and Play compatibility and power management for configuring
and managing all system components, and 32-bit device drivers and installation
procedures for Windows 95/NT and later. Color-coded connectors and descrip-
tive icons make identification easy as required by PC 99.

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:Topreventsystemoverheatand systemdam-
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 98/
Millenium,Windows NT/2000, and OS/2, require much more memory and hard
drive 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 (requires ACPI 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.

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, 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 con-
nectors, or other components.
4. Placecomponentsonagrounded antistatic pad or on thebagthatcamewiththe
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.
