2.1.3 Performance
•UltraPerformance! Onboard IDE Bus Master controller with two connectors
thatsupport fourIDE devicesintwo channels.Supports UltraDMA/66, UltraDMA/
33 (IDE DMA Mode 2), PIO Modes 3 & 4, and supports Enhanced IDE devices,
such as Tape Backup, CD-ROM, CD-R/RW, and LS-120 drives.
• Dual Speeds! CPU frequency can operate at either 66MHz or 100MHz while
systemmemory operatesat either100MHzor66MHz.(100MHzCPUwith 66MHz
SDRAM setting not supported) This asynchronous design can optimize the VGA
performance under shared memory configuration. Of course 100MHz/100MHz
synchronous host/DRAM clock is recommended for maximum performance.
• DoubleorQuadrupletheIDETransferSpeed!IDEtransfersusingUltraDMA/
33 Bus Master IDE can handle rates up to 33MB/s and up to 66MB/s using
UltraDMA/66 technology. The best of all is that these new technology is com-
patible with existing ATA-2 IDE specifications so there is no need to upgrade
current IDE devices or cables.
•Concurrent PCI! Concurrent PCI allows multiple PCI transfers from PCI mas-
ter buses to memory to CPU.
• SDRAM Optimized Performance! ASUS smart series motherboards support the
newgenerationmemory,SynchronousDynamicRandomAccessMemory(SDRAM),
which increases the data transfer rate to 800MB/s max using PC100 SDRAM.
• 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.
• 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. (STR requires OS support and does
not support ISA cards; ISA cards may fail to work coming out of STR mode.)
• New Compliancy! Both the BIOS and hardware levels of the motherboard meet
PC’99 compliancy (on model without ISA). The new PC’99 requirements for
systems and components are based on the following high-level goals: Support for
Plug and Play compatibility and power management for configuring and manag-
ing all system components, and 32-bit device drivers and installation procedures
forWindows95/98/NT. Color-codedconnectors and descriptiveiconsmake iden-
tification easy as required by PC’99.
•Highest Audio Quality! AC’97 DAC/ADC built into the audio CODEC reduces
noisetoimprove audio qualityandperformance for aSNR (signal to noise ratio) of
+90dB. These features greatly improve voice synthesis and recognition.
•Extreme Graphics! The integrated motion compensation allows for smooth
MPEG1 or MPEG2 video playback. Fast 3D graphics engine allows for an ex-
citing gameplay experience.

ASUS MEW User’s Manual 11
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 Socket 370 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 ResourcesAlert! (Requires the future release of LDCM v6.0) Today’s
operating systems such as Windows 98, Windows NT, and OS/2, require much
more memory and hard drive space to present enormous user interfaces and run
large applications. The system resource monitor will warn the user before the
system resources are used up to prevent possible application crashes. Sugges-
tions will give the user information on managing their limited resources more
efficiently.
• DualFunction PowerButton!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 Switch 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)! Chassis 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.

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
This section explains in detail how to change your motherboard’s function settings
through the use of switches and/or jumpers.
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. Placecomponentsona grounded antistatic pad or onthebagthatcame with the
component whenever the components are separated from the system.
Motherboard Feature Settings (DSW)
Besides jumper settings, some of the motherboard’s onboard functions are adjusted
through the DIP switches. The white block represents the switch’s position. The
example below shows all the switches in the OFF position.

2) Voltage I/O Setting (VIO)
This jumper allows you to select the voltage supplied to the DRAM, chipset,
PCI, and the CPU’s I/O buffer. The default voltage should be used unless pro-
cessor overclocking requires a higher voltage.

WARNING! Using a higher voltage may help when overclocking but may result
in the shortening of your computer component’s life. It is strongly recommended
that you leave this setting on its default.
3) Onboard Audio Setting (available on audio model only)
The onboard audio CODEC may be enabled or disabled using all of these jump-
ers. Disable the onboard audio CODEC if you are using an ISA or PCI audio card
on any of the expansion slots or a primaryAMR on theAMR slot (seeAMR Slot
laterinthis section).Ifusingan ISAor PCIaudioexpansion card, OnboardAC’97
Audio Controller in 4.2 I/O Device Configuration must also be disabled.
