BIOS

• Award BIOS, Windows® 98/2000/ME/XP Plug and Play
compatible

• Flash EPROM for easy BIOS upgrades

• Supports DMI 2.0 function

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 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 and overheat
alarm

• Monitors 5VSB/VBAT/3.3V/5V/±12V/CPU voltages
and failure alarm

• Monitors the fan speed of the CPU fan, system fan
and second fan; and failure alarm

• Automatic system fan and second fan on/off control

• Read back capability that displays temperature,
voltage and fan speed

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 PWR­BTTN” 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-On-Keyboard/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 4 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 By Alarm” 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 Plug­and-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.

Year 2000 Compliant

• Supports hardware Y2K function.

• Supports hardware Random Number Generator (RNG)

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 three 168-pin DIMM (Dual In­line Memory Module) sockets that support unbuffered PC-133/PC­100 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.

The system board also supports the ECC (Error Checking and
Correction) function. To use this function, you must install DIMM that
supports parity. Refer to chapter 1 (System Memory section) for
