This page contains a summary of the important notes that must be
given special attention to prior to using the system board.
Over Voltage
The Over Voltage function allows you to manually adjust to a higher
core voltage that is supplied to the CPU. Although this function is
supported, we do not recommend that you use a higher voltage
because unstable current may be supplied to the system board
causing damage.
CPU Overclocking
The CPU Overclocking function allows you to adjust the processors
bus clock by 1MHz stepping. However, overclocking may result to
the processors or systems instability and are not guaranteed to
provide better system performance.
GPA
The system board supports 4MB display cache. To use this function,
you must install a 4MB GPA (Graphics Performance Accelerator)
card into the AGP slot.The GPA card is optional.
Processor
 The frequency ratio of some processors may have been locked
by the manufacturer. If you are using this kind of processor,
setting an extended ratio for the processor will have no effect.
The system will instead use its factory default ratio.
 The frequency ratio of processors greater than 8x has been
locked by the manufacturer and will no longer have the flexibility
of using extended ratios. Therefore, the system will use the
processors factory default ratio.
 If you want to manually select the CPUs FSB (using JP9 and
JP10) instead of using its default setting which is Auto, make sure
the Open Slight Adjust field in the CPU Frequency Control
submenu of the BIOS is set to Disabled.

5VSB Power
 If you are using the (1) Wake-On-KB/Mouse, (2) Wake-On-LAN
and/or (3) Wake-On-Ring (internal modem) functions, the 5VSB
power source of your power supply must support ≥720mA.
 If you are using the Suspend to RAM function, the 5VSB power
source of your power supply must support ≥1A.
 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 must
support ≥2A.
Drivers
Make sure to reboot the system after each driver installation.
Problems will occur if you reboot only after installing all the drivers.

1.1.3 Intelligence
Over Voltage
The Over Voltage function allows you to manually adjust to a higher
core voltage that is supplied to the CPU. Although this function is
supported, we do not recommend that you use a higher voltage
because unstable current may be supplied to the system board
causing damage. Refer to CPU Vcore Select in the CPU Frequency
Control section in chapter 3 for more information.
CPU Overclocking
The CPU Overclocking function allows you to set the processors
bus clock by 1MHz stepping. However, overclocking may result to
the processors or systems instability and are not guaranteed to
provide better system performance. Refer to Open Slight Adjust
and Clock By Slight Adjust in the CPU Frequency Control section
in chapter 3 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-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 and Resume On Ring in the Power
Management Setup section in chapter 3 for more information.
Important:
If you are using a modem add-in card, the 5VSB power source
of your power supply must support ≥ 720mA.

Introduction

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 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-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
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
The Wake-On-USB Keyboard function allows you to use a USB
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 2 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.

1
Introduction
15
 If you are using the Wake-On-USB Keyboard function for 4
USB ports, the 5VSB power source of your power supply
must support ≥ 2A.
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. Refer to Resume
On Alarm in the Power Management Setup section in chapter 3 for
more information.
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®98/2000 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®98/2000 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.

2.2 System Memory
The system board is equipped with
three 168-pin DIMM (Dual In-line
Memory Module) sockets that support
unbuffered PC-133/PC-100 SDRAM
DIMM for 133MHz/100MHz 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.
Refer to System Memory Frequency in the Advanced Chipset
Features section in chapter 3 for more information.
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.
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.
