supports peripheral devices that meet the IrDA and ASKIR standard.
USB Ports
The system board supports 6 USB por ts. Two onboard USB por ts
are located at the ATX double deck ports of the board. The J29
and J31 connectors on the system board allow you to connect 4
more optional USB ports. These optional USB ports, which are

DMI utility in the BIOS automatically records various information
about your system configuration and stores these information in the
DMI pool, which is a part of the system board's Plug and Play
BIOS. DMI, along with the appropriately networked software, is
designed to make inventory, maintenance and troubleshooting of
computer systems easier. Refer to chapter 4 for instructions on using
the DMI utility.
Introduction

1.1.2 System Health Monitor Functions
The system board is capable of monitoring the following system
health conditions.
Monitors CPU/system temperature
Monitors ±12V/±5V/3.3V/VCORE voltages
Monitors CPU/chassis fan speed
Automatic chassis fan on/off control
Read back capability that displays temperature, voltage and fan
speed
Refer to the PC Health Status section in chapter 3 and the
Hardware Monitor section in chapter 4 for more information.
1.1.3 Intelligence
CPU Fan Protection
The CPU Fan Protection function has the capability of monitoring the
CPU fan during system boot-up and will automatically power-off the
system once it has detected that the CPU fan did not rotate. This
preventive measure has been added to protect the CPU from
damage and insure a safe computing environment. Refer to CPU
Fan Connector with CPU Fan Protection Function in chapter 2 and
CPU Fan Protection in the PC Health Status section in chapter 3
for more information.
Over Voltage
The Over Voltage function allows you to manually adjust to a higher
core voltage that is supplied to the CPU. Although this function is
supported, we do not recommend that you use a higher voltage
because unstable current may be supplied to the system board
causing damage. Refer to CPU-Vcore Adjust in the Frequency/
Voltage Control section in chapter 3 for more information.
Introduction
12
CPU Overclocking
The CPU Overclocking function allows you to adjust the processors
bus clock. However, overclocking may result to the processors or
systems instability and are not guaranteed to provide better system
performance. Refer to Clock By Slight Adjust in the Frequency/
Voltage Control section in chapter 3 for more information.
Automatic Chassis Fan Off
The chassis fan will automatically turn off once the system enters the
Suspend mode.
Dual Function Power Button
Depending on the setting in the Soft-Off By PWRBTN field of the
Power Management Setup, this switch will allow the system to enter
the Soft-Off or Suspend mode.
Wake-On-Ring
This feature allows the system that is in the Suspend mode or Soft
Power Off mode to wake-up/power-on to respond to calls coming
through an internal or external modem. Refer to Wake-On-Ring
Connector in chapter 2 and Resume On LAN/Ring (Wake Up
Events field) in the Power Management Setup section in chapter 3
for more information.
Important:
If you are using a modem add-in card, the 5VSB power source
of your power supply must support a minimum of ≥720mA.
RTC Timer to Power-on the System
The RTC installed on the system board allows your system to
automatically power-on on the set date and time. Refer to Resume
By-Alarm (Wake Up Events field) in the Power Management
Setup section in chapter 3 for more information.
Introduction
13
Wake-On-LAN
The Wake-On-LAN function allows the network to remotely wake
up a Soft Power Down (Soft-Off) PC . Your LAN card must support
the remote wakeup function. Refer to Wake-On-LAN Connector in
chapter 2 and Resume On LAN/Ring (Wake Up Events field) in
the Power Management Setup section in chapter 3 for more
information.
Important:
The 5VSB power source of your power supply must support a
minimum of ≥720mA.
AC Power Failure Recovery
When power returns after an AC power failure, you may choose to
either power-on the system manually, let the system power-on
automatically or return to the state where you left off before power
failure occurs. Refer to PWR Lost Resume State in the Power
Management Setup section in chapter 3 for more information.
ACPI STR
The system board is designed to meet the ACPI (Advanced
Configuration and Power Interface) specification. ACPI has energy
saving features that enables PCs to implement Power Management
and Plug-and-Play with operating systems that support OS Direct
Power Management. Currently, only Windows® 98/2000/ME suppor ts
the ACPI function allowing you to use the Suspend to RAM function.
With the Suspend to RAM function enabled, you can power-off the
system at once by pressing the power button or selecting Standby
when you shut down Windows® 98/2000/ME without having to go
through the sometimes tiresome process of closing files, applications
and operating system. This is because the system is capable of
storing all programs and data files during the entire operating session
into RAM (Random Access Memory) when it powers-off. The
operating session will resume exactly where you left off the next time
you power-on the system. Refer to Using the Suspend to RAM
Function in appendix A for more information.
Important:
The 5VSB power source of your power supply must support
≥
1A.
Introduction

Virus Protection
Most viruses today destroy data stored in hard drives. The system
board is designed to protect the boot sector and partition table of
your hard disk drive.

2.2 System Memory
Warning:
To ensure proper boot up and operation of your system, you
must power-off the system then turn off the power supplys
switch or unplug the AC power cord prior to altering the setting
of a jumper or replacing the CPU.
Electrostatic discharge (ESD) can damage your system board,
processor, disk drives, add-in boards, and other components.
Perform the upgrade instruction procedures described at an ESD
workstation only. If such a station is not available, you can provide
some ESD protection by wearing an antistatic wrist strap and
attaching it to a metal part of the system chassis. If a wrist
strap is unavailable, establish and maintain contact with the
system chassis throughout any procedures requiring ESD
protection.
The system board is equipped with two 184-pin DDR SDRAM
DIMM (Dual I n-line Memory Module) sockets that suppor t 2.5V
DDR SDRAM DIMM. Double Data Rate SDRAM (DDR SDRAM) is
a type of SDRAM that doubles the data rate through reading and
writing at both the rising and falling edge of each clock. This
effectively doubles the speed of operation therefore providing two
times faster data transfer.
18
Hardware Installation
2.2.1 Installing the DIM Module
A DIM module simply snaps into a DIMM socket on the system
board. Pin 1 of the DIM module must correspond with Pin 1 of the
socket.
The system board is also equipped with two 168-pin PC SDRAM
DIMM (Dual In-line Memory Module) sockets that support 3.3V PC
SDRAM DIMM. PC SDRAM (Synchronous Dynamic Random Access
Memory) uses a fast memory interface technology that includes using
the clock on the chip to synchronize with the CPU clock so that the
timing of the memory chips and the timing of the CPU are
synchronized. This saves time during transmission of data,
subsequently increasing system performance.
The auto voltage switch function can automatically switch between
2.5V DDR SDRAM and 3.3V PC SDRAM DIMMs.
Important:
DO NOT use DDR SDRAM DIMM and PC SDRAM DIMM at
the same time.
Refer to chapter 1 (System Memory section) for detailed
specification of the memory supported by the system board.

Important:
We do not recommend that you adjust the CPU to a higher
frequency ratio because it may result to the CPUs or systems
instability and are not guaranteed to provide better system
performance. If you are unable to boot up the system with the
frequency ratio you selected, please power off the system and
set SW1 pins 1-5 to Off (Auto).
L1s four bridges closed (short).
L1s four bridges open.
CPU Frequency Ratio Select - SW1
The table shows the available frequency ratios and their
corresponding DIP switch setting. The black rectangles on the SW1
illustration denote the part that is protruding, the adjustable switch.
Make sure SW1 is set correctly before applying power, otherwise
you will not be able to power-on the system.
Not all AMD CPUs support the multiplier overclocking function.
Please give special attention to L1 on the CPU. L1s four bridges
must be closed (short) in order for the frequency ratio selected on
SW1 to take effect. The figure below will help you identify the type
of CPU that would allow you to adjust its frequency ratio.
