Desktop Management Interface (DMI)

The system board comes with a DMI 2.0 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 par t 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

• Supports Intel® processor thermal diode output (real processor
temperature)

• Opened chassis alarm

Refer to the “PC Health Status” section in chapter 3 and the
“Hardware Doctor” section in chapter 4 for more information.

1.1.3 Intelligence

Automatic System/Second Fan Off

The system and second fans will automatically turn off once the
system enters the Suspend mode.

Dual Function Power Button

Depending on the setting in the “Soft-Off By PWR-BTTN” 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 Ring” 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 ≥720mA.

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” in the Power Management Setup
section in chapter 3 for more information.

Important:

The 5VSB power source of your power supply must support

≥

720mA.

Wake-On-Keyboard/Wake-On-Mouse

This function allows you to use the keyboard or PS/2 mouse to
power-on the system. Refer to “Jumper Settings for Wake-On­Keyboard/Wake-On-Mouse” in chapter 2 and “Keyboard/Mouse
Power On” in the Integrated Peripherals section in chapter 3 for
more information.

Important:

• The power button will not function once a keyboard
password has been set in the “KB Power On Password”
field of the Integrated Peripherals submenu. You must type
the correct password to power-on the system. If you forgot
the password, power-off the system and remove the
battery. Wait for a few seconds and install it back before
powering-on the system.

• The 5VSB power source of your power supply must
support ≥720mA.

Wake-On-USB Keyboard

The Wake-On-USB Keyboard function allows you to use a USB
keyboard to wake up a system that is in the S3 (STR - Suspend To
RAM) state. Refer to “Jumper Settings for Wake-On-USB Keyboard”
in chapter 2 and “USB KB Wake-Up From S3” in the Power
Management Setup section in chapter 3 for more information.

Important:

• If you are using the Wake-On-USB Keyboard function for 2
USB ports, the 5VSB power source of your power supply
must support ≥1.5A.

• If you are using the Wake-On-USB Keyboard function for 3
or more USB ports, the 5VSB power source of your power
supply must support ≥2A.

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
On Alarm” in the Power Management Setup section in chapter 3 for
more information.

Introduction

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/XP
supports the ACPI function. ACPI when enabled in the Power
Management Setup will allow 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/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 5VSB power source of your power supply must support

≥

1A.

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 Integrated
Peripherals section in chapter 3 for more information.

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:

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 168-pin DIMM (Dual In-line
Memory Module) sockets that support unbuffered PC-133/PC-100
SDRAM DIMM for 133MHz/100MHz system memory bus. PC
SDRAM (Synchronous Dynamic Random Access Memory) is a fast
memory interface technology that uses 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.

Refer to chapter 1 for the type of memory suppor ted by the
system board.

2.8.2 PS/2 Mouse and PS/2 Keyboard Ports

The system board is equipped with an onboard PS/2 mouse
(Green) and PS/2 keyboard (Purple) ports - both at location CN6
of the ATX double deck ports of the system board. The PS/2
mouse port uses IRQ12. If a mouse is not connected to this port,
the system will reserve IRQ12 for other expansion cards.

Warning:

Make sure to turn off your computer prior to connecting or
disconnecting a mouse or keyboard. Failure to do so may
damage the system board.
