2.1.3 Performance
•UltraPerformance:OnboardIDE Bus Master controllerwithtwoconnectorsthat
support four IDE devices in two channels. Supports UltraDMA/66, UltraDMA/33
(IDEDMAMode2),PIOModes 3 & 4, andsupportsEnhancedIDEdevices,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 Configuration andPowerInterface)isalso imple-
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.
•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 fall asleep waiting for system bootup.
•NewCompliancy:Both the BIOS and hardware levels of the motherboard meet
PC 99 compliancy. The new PC 99 requirements for systems and components
are based on the following high-level goals: support for Plug and Play compat-
ibility and power management for configuring and 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 as
required by PC 99.

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-OffSwitchLeadin3.8External 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 if there are messages waiting in the email inbox. A simple glimpse
provides useful information 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.

3.3 Hardware Setup Procedure
Before using your computer, you must complete the following steps:
•Check Motherboard Settings
•Install Memory Modules
•Install the Central Processing Unit (CPU)
•Install Expansion Cards
•Connect Ribbon Cables, Panel Wires, and Power Supply
3.4 Motherboard Settings
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, 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. Placecomponentsonagroundedantistatic pad or on the bagthatcamewiththe
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.

3) Safe Mode Setting (JP10)
Usually Slot 1 processors have locked frequency multiples. In this case, there is
no way to exceed the specified multiple whether through motherboard settings or
BIOS setup. With unlocked Slot 1 processors, exceeding the specified multiple is
possiblethroughBIOSsetup. Exceeding thespecifiedmultiplemayresult in hang-
ing during bootup. If this occurs, enable Safe Mode to force a multiple of 2 and
100MHz FSB to enter BIOS setup to correct the problem.

4) Automatic Timeout Reboot Setting (JP12)
The motherboard is set so that when the BIOS detects a hang (timeout) during
bootup, the motherboard will automatically reboot. If rebooting is repeating in-
effectively, set this jumper to No Reboot to disable auto-reboot. However, if
Safe Mode Setting (JP10) is set to Safe Mode, setting Automatic Timeout
Reboot Setting (JP12) to No Reboot will bring the system to Safe Mode so you
may correct any problem.
