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 and Resume On Ring in the Power

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 and Resume On LAN in the Power Management Setup

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

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 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

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/ 000/ME 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/ 000/ME 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 three 168-pin DIMM (Dual In-
line Memory Module) sockets that support unbuffered PC-133
SDRAM DIMM for 133MHz 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
detailed specification of the memory supported by the system
board.

Hardware Installation
1. Pull the tabs which are at the ends of the socket to the side.
. 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 JP6
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 ratio/clock 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.
. Set JP6 pins and 3 to On. Wait for a few seconds and set JP6
back to its default setting, pins 1 and On.

menu of the BIOS.
5. Select the CPU Frequency Control submenu and press <Enter>.
6. Set the CPU Clock Ratio or Clock By Slight Adjust field to its
default setting or an appropriate frequency ratio or bus clock.
Refer to the CPU Frequency Control section in chapter 3 for
