The Wake-On-LAN function is applicable only when you are using a
LAN add-in card that has the same function. It 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-OnLAN 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” (“Onboard Super IO Device” field) 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.

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® 98SE/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® 98SE/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.
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” (“Onboard Super
IO Device”) 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

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 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 doubling the
speed of data transfer.
Refer to chapter 1 (System Memory section) for detailed
specification of the memory supported by the system board.

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.
1. Pull the “tabs” which are at the ends of the socket to the side.
2. Position the DIMM above the socket with the “notch” in the
module aligned with the “key” 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.
