1.1.3 Intelligence
Watchdog Timer
The system board supports the Watchdog Timer function. It 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
WatchdogTimer in appendix C for more information.
Automatic CPU/Chassis Fan Off
The CPU and chassis 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-Keyboard/Wake-On-Mouse
This function allows you to use the keyboard or PS/2 mouse to
power-on the system. Refer to “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.
RTCTimer 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
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.
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.
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.
1.2 Package Checklist
The system board package contains the following items:
!The system board
!A user’s manual

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 stacked SODIMM sockets
that support unbuffered PC-133/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.

Clear CMOS Data - Jumper JBAT1
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 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 JBAT1 pins 2 and 3 to On. Wait for a few seconds and set
JBAT1 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 ratio in the BIOS, please proceed to
step 4.
4. After powering-on the system, press <Del> to enter the main
menu of the BIOS.
5. Select the Frequency/Voltage Control submenu and press
<Enter>.
6. Set the “CPU Clock Ratio” field to its default setting or an
appropriate frequency ratio. Refer to the Frequency/Voltage
Control section in chapter 3 for more information.
7. Press <Esc> to return to the main menu of the BIOS setup
utility. Select “Save & Exit Setup” and press <Enter>.
