2.1.3 Performance
•UltraPerformance:OnboardIDE Bus Mastercontrollerwithtwoconnectors that
support four IDE devices in two channels. Supports UltraDMA/66, UltraDMA/33
(IDEDMAMode2),PIO Modes 3 &4,andsupportsEnhancedIDE devices, such
as DVD-ROM, CD-ROM, CD-R/RW, LS-120, and Tape Backup drives.
•Dual Speeds: CPU frequency can operate at either 133MHz or 100MHz.
•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.)
•Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-
ter buses to memory to CPU.
•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, must be used.
•PC 99 Compliancy: Both the BIOS and hardware levels of the motherboard

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 thermal sensing and auto-protec-
tion.
•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.
•SystemResourcesAlert:Today’s operating systems such as Windows 98, Win-
dows NT, and OS/2, require much more memory and hard drive space to present
enormous user interfaces and run large applications. The system resource moni-
tor will warn the user before the system resources are used up to prevent pos-
sible application crashes. Suggestions will give the user information on manag-
ing 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 25)ATX
Power/Soft-OffSwitchLeadin3.8 External Connectors for more information)
button. Regardless of the setting, pushing the power button for more than 4 sec-
onds 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 the stage the computer is in. A simple glimpse provides useful infor-
mation to the user.
•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.

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.
Motherboard Feature Settings
The motherboard’s onboard functions are either adjusted through jumpers or DIP
switches. When using DIP switches, the white block represents the switch’s posi-
tion. The example below shows all the switches in the OFF position.

1) JumperFree™ Mode (JEN)
This jumper allows you to enable or disable the JumperFree™ mode. The
JumperFree™ mode allows processor settings to be made through the BIOS
setup (see 4.4 Advanced Menu).
NOTE: In JumperFree™ mode, all dip switches (DSW) must be set to OFF.

2) CPU External Frequency Setting (DSW-1, -2, -3, -4, -5)
This option tells the clock generator what frequency to send to the CPU and the
PCI bus. This allows the selection of the CPU’s External frequency.
IMPORTANT:
1. In JumperFree mode, all dip switches (DSW-1–DSW-5) must be set to OFF.
2. When JumperFree mode is enabled, use BIOS setup in place of these switches
(see CPU Speed in 4.4 Advanced Menu).
NOTE: Only selected switches are illustrated. For a complete frequency listing,
see next page.

NOTE:If your processor does not have a locked Frequency Multiple, you must
use CPU Core:Bus Freq. Multiple in 4.4 Advanced Menu of the BIOS setup
to set the Frequency Multiple. If the Frequency Multiple is locked, setting the
Frequency Multiple in BIOS setup will have no effect.
