1. INTRODUCTION
IMPORTANT: It is strongly recommended that at least a 200-watt (235W for full
configuration) ATX power supply be used for this motherboard. Make sure that
your ATX power supply can supply at least 20 amperes on the +5-volt lead and
10mAon the +5-volt standby lead (+5VSB) (see 19)ATX Power Suppy Connec-
tor in 3.8 External Connectors). Your system may become unstable/unreliable
and may experience difficulty in powering up if your power supply is inadequate.

2.1.2 Performance
•100/100MHz Synchronous Host/DRAM Clock Support: CPU frequency can
operate at 100MHz while system memory operates at 100MHz.
•High-Speed Data Transfer Interface: 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.
•SDRAM Optimized Performance: This motherboard supports the new genera-
tion memory, Synchronous Dynamic RandomAccess Memory (SDRAM), which
increasesthedatatransferrateto800MB/smaxusingPC100-compliantSDRAM.
•ACPI Ready: ACPI (Advanced Configuration and Power Interface) provides
more Energy Saving Features for future operating systems (OS) supporting OS
Direct Power Management (OSPM) functionality. With these features imple-
mented 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.
•PC99Compliancy:BoththeBIOS and hardwarelevelsofthe motherboardmeets
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 compatibility
and power management for configuring and managing all system components,
and 32-bit device drivers and installation procedures for Windows 95/98/NT.

Intelligence
2.1.3 Intelligence (only with optional hardware monitor)
•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.
•Voltage Monitoring andAlert: Processor and system voltage levels are moni-
tored to ensure stable current to critical motherboard components. Voltage speci-
fications are more critical for future processors, so monitoring is necessary to
ensure proper system configuration and management.
•Auto Fan Off: The system fans will power off automatically even in sleep
mode. This function reduces both energy consumption and system noise, and is
an important feature to implement silent PC systems.
•Remote Ring On (requires modem): This allows a computer with this
motherboard to be turned on remotely through an internal or external modem.
With this feature, users can access their computer from anywhere in the world!

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 Inte-
grated Circuit (IC) chips. To protect them against damage from static electricity, 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 not have
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 connectors, or
other components.
4. Place components on a grounded antistatic pad or on the bag that came with the compo-
nent 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 (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.

This jumper lets you select the onboard 3.3Vfrom the motherboard if yourATX
power supply does not have a 3.3V lead and 3.3V optional components are
mounted on the motherboard. This motherboard normally does not have the
3.3V components and therefore requires a standard ATX power supply with its
own 3.3V lead.

4) CPU External Frequency Setting (DSW)
Thisoptiontellsthe clock generator what frequencytosendtothe CPU, SDRAM,
and the chipset. This allows the selection of the CPU’s External frequency. The
CPUExternalFrequencymultipliedbytheFrequency Multiple equals the CPU’s
Internal frequency (the advertised CPU speed).The CPU is running at the same
speed as the SDRAM.
NOTE: To use this feature, CPU Frequency Selection in BIOS setup must be
set to [By Jumper] (see 4.4.2 Advanced Chipset Setup).
