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,andsupportsEnhanced IDE 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.)

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 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
proceduresforWindows95/98/NT. Color-codedconnectorsanddescriptiveicons
make identification easy as required by PC 99.

and failure. All the fans are set for its normal RPM range and alarm thresholds.
•TemperatureMonitoringandAlert:Topreventsystemoverheatandsystemdam-
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.
•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
enormoususerinterfacesandrun largeapplications.The onboard hardwareASUS
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 25)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.

•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. Placecomponentsonagrounded antistatic pad or onthebagthatcame with the
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.

WARNING! Make sure that you unplug your power supply when adding or
removing system components. Failure to do so may cause severe damage to
your motherboard, peripherals, and/or components. The onboard LED when
lit acts as a reminder that the system is in suspend or soft-off mode and not
powered OFF.

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 (SW2) must be set to OFF.

3) Safe Mode Setting (SAFE_MODE)
Usually 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 processors, exceeding the specified multiple is possible
through BIOS setup. Exceeding the specified multiple may result in hanging dur-
ing bootup. If this occurs, enable Safe Mode to force a multiple of 2 and 100MHz
FSB to enter BIOS setup to correct the problem.

2) USB Device Wake Up (USBPWR)
This allows you to disable or enable the USB device power up function. Set this
jumper to Enable if you wish to use your USB device to wake up your computer.
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. Your computer will not power ON if you set this
toEnableand donothavethe appropriateATXpowersupply. NOTE:Thisjumper
must be set in conjunction with Wake On USB Device in 4.5.1 Power Up Control.
NOTE: For suspend to RAM function, this jumper must be set to Enable.

4) Automatic Timeout Reboot Setting (NO_REBOOT)
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 (SAFE_MODE) is set to Safe Mode, setting Automatic
Timeout Reboot Setting (NO_REBOOT) to No Reboot will bring the system
to Safe Mode so you may be able to correct any problems.

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 later in this section). If using an ISA or PCI audio expansion card, On-
boardAC97Audio Controllerin 4.4.2 I/O Device Configuration must also be
disabled.
