Dual Function Power Button
Depending on the setting in the BIOS setup, this switch will allow
the system to enter the Soft-Off or Suspend mode.
Watchdog Timer
The Watchdog Timer function allows your application to regularly
“clear” the system at the set time interval. If the system hangs or
fails to function, it will reset at the set time interval so that your
system will continue to operate. Refer to “Watchdog Timer Select”
in the Integrated Peripherals setup of the Award BIOS.
External Modem Ring-on
The Modem Ring-on feature allows the system that is in the
Suspend mode or Soft Power Off mode to wake-up/power-on to
respond to incoming calls.

This feature supports external modem only.
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.

Introduction

Wake-On-LAN Ready
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.
Important:
The 5VSB power source of your power supply must support
≥ 720mA (minimum).
Wake-On-Keyboard/Wake-On-Mouse
This function allows you to use the keyboard or 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 of the Award BIOS 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 setup. You must type
the correct password to power-on the system.
• The 5VSB power source of your power supply must
support ≥ 720mA (minimum).
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.
ACPI
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.

2.2 System Memory
The system board is equipped with three 168-pin DIMM (Dual
In-line Memory Module) sockets that support x64/x72 unbuffered
or registered PC SDRAM DIMM, 3.3V. 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 system board also supports the ECC (Error Checking and
Correction) function. To use this function, you must install DIMM
that supports parity. That is, DIMM that typically has 9 memory
chips per side. This kind of module has 8 standard memory chips
and a parity chip. DIMM with no parity has 8 standard memory
chips only. Refer to chapter 1 (System Memory section) for
detailed specification of the memory supported by the system
board.
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.

1. Pull the “tabs” which are at the ends of the socket to the side.
2. Position the DIMM above the socket with the “notches” in the
module aligned with the “keys” on the socket.
3. Seat the module vertically into the socket. Make sure it is
completely seated.The tabs will hold the DIMM in place.
2.3 Frequency Ratio Settings for Processors
Make sure you have set JP11 according to the type of processor
installed in the system board.
In the example on the left:
Switch1:Off
Switch2:On
Switch3:Off
Switch4:On
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 default setting is Auto - the
system will automatically run
according to the FSB of the
processor.
Warning:
Overclocking a 66MHz FSB
processor to 100MHz will
provide better system
performance. However, not all
66MHz FSB processors are
capable of running at
100MHz bus speed.
Therefore, if you are unable to boot your system when set at
100MHz, make sure to set JP2 and JP3 back to their default
settings.

reconfigured with the default values
stored in the ROM BIOS. To load
the default values, power off your
system and unplug the power
cord. Set JP8 pins 2 and 3 to On.
Wait for a few seconds and set JP8
back to its default setting, pins 1 and

Jumper JP1
Wake-On-Keyboard/Wake-On-Mouse
The system board supports the
Wake-On-Keyboard/Wake-On-
Mouse function. This function allows
you to use the keyboard or PS/2
mouse to power-on the system. By
default, JP1 is disabled. To use this
function, set JP1 to 2-3 On.
“Keyboard/Mouse Power On” in
the Integrated Peripherals setup of
the Award BIOS must be set
accordingly. Refer to chapter 3 for
details.
Warning:
1. If JP1 was previously enabled with a password set in the
“KB Power On Password” field, and now you wish to
disable the Wake-On-Keyboard (password) function, make
sure to set the “Keyboard/Mouse Power On” field to
Disabled prior to setting JP1 to disabled. You will not be
able to boot up the system if you fail to do so.
2. The power button will not function once a keyboard
password has been set in the “KB Power On Password”
field of the Integrated Peripherals setup. You must type
the correct password to power-on the system.
3. The 5VSB power source of your power supply must
support ≥ 720mA (minimum).
