Desktop Management Interface (DMI)
The system board comes with a DMI .0 built into the BIOS. The
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.
1.1.2 System Health Monitor Functions
The system board is capable of monitoring the following system
health conditions.
 Monitors CPU/system temperature
 Monitors ±1 V/±5V/3.3V/CPU/VBAT(V)/5VSB(V) 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 Temperature Protection
The CPU Temperature Protection function has the capability of
monitoring the CPUs temperature during system boot-up. Once it
has detected that the CPUs temperature exceeded the CPU
temperature limit defined in the BIOS, the system will automatically
power-off after 5 warning beeps. Refer to CPU Temp. Prot. Function
and CPU Temp. Prot. Alarm in the PC Health Status section in
chapter 3 for more information.

Introduction
11
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 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.
CPU Overclocking
The CPU Overclocking function allows you to adjust the processors
bus clock. However, overclocking may result to the processors or
systems 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.

Introduction

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 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 VSB 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.
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 and Resume On LAN/Ring (Wake Up Events field) in
the Power Management Setup section in chapter 3 for more
information.
Important:
The VSB 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.

Introduction
13
ACPI STR
The system board is designed to meet the ACPI (Advanced Con-
figuration 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/ 000/ME/XP
supports the ACPI function allowing you to use the Suspend to
RAM function. The Suspend to RAM function is optional.
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/ 000/ME/XP 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 VSB power source of your power supply must support
≥ 1A.
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 supplys
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 three 184-pin DDR SDRAM
DIMM (Dual In-line Memory Module sockets that support 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.
