Introduction
11
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 for more information.
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.
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.
Important:
If you are using the (1) Suspend to RAM, (2) Wake-On-
Keyboard/Mouse and (3) Wake-On-LAN functions all at the
same time, the 5VSB power source of your power supply must
support a minimum of ≥ 1A. A ≥ 720mA 5VSB power source is
sufficient if you are using only one or two of these functions.
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

Introduction

the password, power-off the system and remove the
battery. Wait for a few seconds and install it back before
powering-on the system.
• If you are using the (1) Suspend to RAM, (2) Wake-On-
Keyboard/Mouse and (3) Wake-On-LAN functions all at the
same time, the 5VSB power source of your power supply
must support a minimum of ≥ 1A. A ≥ 720mA 5VSB power
source is sufficient if you are using only one or two of these
functions.
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) to en-
able a new security and manageability infrastructure for PC.
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. Currently, only Windows®®
®®
®98 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 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:
If you are using the (1) Suspend to RAM, (2) Wake-On-
Keyboard/Mouse and (3) Wake-On-LAN functions all at the
same time, the 5VSB power source of your power supply must
support a minimum of ≥ 1A. A ≥ 720mA 5VSB power source is
sufficient if you are using only one or two of these functions.
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
The system board is equipped
with two 168-pin DIMM (Dual In-
line Memory Module) sockets that
support unbuffered PC-100
SDRAM DIMM. 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 onboard VGA shares 1MB of the system memory. This is fixed
regardless of the size of the system memory. Aside from the 1MB
shared memory, it also uses Dynamic Video Memory Technology
(DVMT). DVMT freely changes in size because graphics memory is
allocated from the system memory according to current needs.
Refer to chapter 1 for the type of memory supported by the
system board.
Display Cache
The system board is mounted with 2 SDRAMs that serve as 4MB
display cache. The presence of the display cache will provide better
system performance.
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.

Hardware Installation
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 Jumper Settings for Clearing CMOS Data
Clear CMOS Data - Jumper JP5
If you encounter the following,
a) CMOS data becomes
corrupted.
b) You forgot the supervisor or
user password.
c) You are unable to boot-up the
computer system because the
processor’s clock/ratio was
incorrectly set in the BIOS.
you can reconfigure the system
with the default values stored in
the ROM BIOS.
To load the default values stored in the ROM BIOS, please follow
the steps below.
1. Power-off the system.
2. Set JP5 pins 2 and 3 to On. Wait for a few seconds and set JP5
back to its default setting, pins 1 and 2 On.
3. Now power-on the system.
If your reason for clearing the CMOS data is due to incorrect
setting of the processor’s clock/ratio in the BIOS, please proceed
to step 4.
4. After powering-on the system, press <Del> to enter the BIOS
setup utility.
5. Select the CPU Frequency Control submenu and press <Enter>.
6. Set the “CPU/PCI Clock (MHz)” or “CPU Clock Ratio” field to
its default setting or an appropriate bus clock or frequency ratio.
Refer to the CPU Frequency Control section in chapter 3 for
more information.

Wake-On-Keyboard/Wake-On-Mouse - Jumper JP1
The Wake-On-Keyboard/Wake-On-
Mouse 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 Periph-
erals submenu of the BIOS must be
set accordingly. Refer to chapter 3
for details.
Warning:
1. If JP1 was enabled with a
password set in the “KB Power On Password” field, and now
you wish to disable the 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 submenu. You must type
the correct password to power-on the system.
