1.1.3 Intelligence

W atchdog Timer

The system board suppor ts the Watchdog Timer function. It allows
your application to regularly “clear” the system at the set time
inter val. If the system hangs or fails to function, it will reset at the set
time inter val so that your system will continue to operate. Refer to
Watchdog Timer 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.

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
By Alar m” 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
Peripher als section in chapter 3 for more information.

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.

2.4.4 Floppy Disk Drive Connector

The system board is equipped with a shrouded floppy disk drive
connector that suppor ts two standard floppy disk drives. To prevent
improper floppy cable installation, the shrouded floppy disk header
has a keying mechanism. The 34-pin connector on the floppy cable
can be placed into the header only if pin 1 of the connector is
aligned with pin 1 of the header. You may enable or disable this
function in the Integrated Peripherals submenu of the BIOS.

Connecting the Floppy Disk Drive Cable

1. Install the 34-pin header connector of the floppy disk drive cable
into the shrouded floppy disk header (FDD1) on the system
board. The colored edge of the ribbon should be aligned with pin
1 of FDD1.

2. Install the other 34-pin header connector(s) into the disk drive(s).
Align the colored edge of the daisy chained ribbon cable with pin
1 of the drive edge connector(s). The end-most connector should
be attached to the drive you want to designate as Drive A.

Hardware Installation

2.4.5 IDE Disk Drive Connector

The system board is equipped with two shrouded PCI IDE headers
that will interface four Enhanced IDE (Integrated Drive Electronics)
disk drives. To prevent improper IDE cable installation, each shrouded
PCI IDE header has a keying mechanism. The 40-pin connector on
the IDE cable can be placed into the header only if pin 1 of the
connector is aligned with pin 1 of the header. You may enable or
disable the onboard primary or secondary IDE controller in the
Integrated Peripherals submenu of the BIOS.

Connecting the IDE Disk Drive Cable

1. If you are connecting two IDE drives, install the 40-pin connector
of the IDE cable into the primar y shrouded IDE header (IDE1). If
you are adding a third or fourth IDE device, install the 40-pin
connector of the other IDE cable into the secondary shrouded
IDE header (IDE2).

2. Install the other 40-pin header connector(s) into the device with
the colored edge of the ribbon cable aligned with pin 1 of the
drive edge connector(s).

Note:

Refer to the disk drive user’s manual for information about
selecting proper drive settings.
