power supply provides a range of 4.75 volts minimum to 5.25 volts maximum DC power source.

Power Consumption

For typical configurations, the CPU board is designed to operate with at least a 250 W power supply. A
higher-wattage power supply should be used for heavily-loaded configurations. The power supply must
meet the following requirements:

- Rise time for power supply: 2 ms - 20 ms

- Minimum delay for reset to Power Good: 100 ms

- Minimum Power down warning: 1 ms

The following table lists the power supply’s tolerances for DC voltages:

3. Hardware Installations

CPU Installation

The SPC-8520-LA supports a single Intel(R) Celeron M or Pentium M processor (FSB 400MHz). The
processor’s VID pins automatically program the voltage regulator on the CPU board to the required
processor voltage. The host bus speed is automatically selected. The processor connects to the CPU
board through the 478-pins socket.

The socket-478 contains a turn lock to secure the processor. Make sure the notch on the corner of the
CPU corresponds with the notch on the inside of the socket.

The CPU should always have a Heat Sink and a cooling fan attached to prevent overheating.
Refer to the user’s guide of optional heat sink fan appending for attachment of a heat sink fan.
(The user’s manual for the optional heat sink fan [HSF-PM] is available on the CD-ROM attached to this

product.)

CAUTION

Ensure that the CPU heat sink and the CPU top surface are in total contact to avoid CPU overheating
problem that would cause your system to hang or be unstable.

6. Watch-Dog-Timer (WDT) Setting

The watchdog timer serves as a safeguard against possible system lock-up in your industrial computer
system. In most industrial environments, there are heavy equipment, generators, high-voltage power
lines, or power drops that have adverse effects on your computer system. For instance, when a power
drop occurs, it could cause the CPU to come to a halt state or enter into an infinite loop, resulting in a
system lock-up.

The application software created by user with the watchdog timer enabled, a RESET automatically
generated unless the software periodically triggers the timer within the setting time-out interval. That is,
while the system gets hung up, the running program can’t trigger the timer periodically. The timer will
generate a reset signal to reboot the system. This feature allows a running program to restart in an
orderly way when a power glitch or any abnormal condition occurs.

The watchdog timer comes with 255-level time-out interval, 1 - 255 seconds per interval, which can be
adjusted by software setting. There is a tolerance of 2 second for this time-out interval. For example,
if the time-out interval has been set to 32 seconds, your program should trigger the watchdog timer before
28 seconds are escaped. Otherwise, after 28-32 seconds are escaped, the system will automatically
reboot. To keep the system running normally, your program should trigger the watchdog timer every 28
seconds.

The I/O port is defined at address 2eH. You can trigger/enable disable the timer by writing address 2e.
Here is an example for flow chart and programming how to use the watch-dog-timer.

7. BIOS Setup

Introduction

This chapter discusses Award’s Setup program built into the FLASH ROM BIOS. The Setup program
allows users to modify the basic system configuration. This special information is then stored in battery­backed RAM so that it retains the Setup information when the power is turned off.

The rest of this chapter is intended to guide you through the process of configuring your system using
Setup.

Starting Setup

The Award BIOS is immediately activated when you first power on the computer. The BIOS reads the
system information contained in the CMOS and begins the process of checking out the system and
configuring it. When it’s finish , the BIOS will seek an operating system on one of the disks and then
launch and turn control over to the operating system.

While the BIOS is in control, the Setup program can be activated in one of two ways:

1. By pressing <Del> immediately after switching the system on, or

2. By pressing the <Del> key when the following message appears briefly at the bottom of the screen
during the POST (Power On Self-Test).

Press DEL to enter SETUP.

If the message disappears before you respond and you still wish to enter Setup, restart the system to try
again by turning it OFF then ON or pressing the "RESET" button on the system case. You may also
restart by simultaneously pressing <Ctrl>, <Alt>, and <Delete> keys. If you do not press the keys at the
correct time and the system does not boot, an error message will be displayed and you will again be asked
to...

Press F1 to continue, DEL to enter SETUP

Using Setup

In general, you use the arrow keys to highlight items, press <Enter> to select, use the PageUp and
PageDown keys to change entries, press <F1> for help and press <Esc> to quit. The following table
provides more detail about how to navigate in the Setup program using the keyboard.

Getting Help
Press F1 to pop up a small help window that describes the appropriate keys to use and the possible

selections for the highlighted item. To exit the Help Window press <Esc> or the F1 key again.

In Case of Problems
If after making and saving system changes with Setup, you discover that your computer no longer is able

to boot, the AwardBIOS supports an override to the CMOS settings which resets your system to its
defaults.

The best advice is to only alter settings which you thoroughly understand. To this end, we strongly
recommend that you avoid making any changes to the chipset defaults. These defaults have been
carefully chosen by both Award and your systems manufacturer to provide the absolute maximum
performance and reliability. Even a seemingly small change to the chipset setup has the potential for
causing you to use the override.

A Final Note About Setup
The information in this chapter is subject to change without notice.

PnP/PCI Configuration Setup

This section describes configuring the PCI bus system. PCI, or Personal Computer Interconnect, is a
system which allows I/O devices to operate at speeds nearing the speed the CPU itself uses when
communicating with its own special components. This section covers some very technical items and it
is strongly recommended that only experienced users should make any changes to the default settings.

Defaults Menu

Selecting “Defaults” from the main menu shows you two options which are described below

Load Fail-Safe Defaults
When you press <Enter> on this item you get a confirmation dialog box with a message similar to:

Load Fail-Safe Defaults (Y/N) ? N

Pressing ‘Y’ loads the BIOS default values for the most stable, minimal-performance system operations.

Load Optimized Defaults
When you press <Enter> on this item you get a confirmation dialog box with a message similar to:

Load Optimized Defaults ( Y/N) ? N

Pressing ‘Y’ loads the default values that are factory settings for optimal performance system operations.

Supervisor/User Password Setting

You can set either supervisor or user password, or both of them. The differences between are:

SUPERVISOR PASSWORD
USER PASSWORD

When you select this unction, the following message will appear at the center of the screen to assist you
in creating a password.

Type the password, up to eight characters in length, and press <Enter>. The password typed now will
clear any previously entered password from CMOS memory. You will be asked to confirm the password.
Type the password again and press <Enter>. You may also press <Esc> to abort the selection and not
enter a password.

To disable a password, just press <Enter> when you are prompted to enter the password. A message
will confirm the password will be disabled. Once the password is disabled, the system will boot and you
can enter Setup freely.

When a password has been enabled, you will be prompted to enter it every time you try to enter Setup.
This prevents an unauthorized person from changing any part of your system configuration.

Additionally, when a password is enabled, you can also require the BIOS to request a password every
time your system is rebooted. This would prevent unauthorized use of your computer.

You determine when the password is required within the BIOS Features Setup Menu and its Security
option (see Section 3). If the Security option is set to “System”, the password will be required both at boot
and at entry to Setup. If set to “Setup”, prompting only occurs when trying to enter Setup.

Save & Exit Setup
Pressing <Enter> on this item asks for confirmation:

Save to CMOS and EXIT (Y/N)? Y

Pressing “Y” stores the selections made in the menus in CMOS – a special section of memory that stays
on after you turn your system off. The next time you boot your computer, the BIOS configures your
system according to the Setup selections stored in CMOS. After saving the values the system is restarted
again.

Exit Without Saving
Pressing <Enter> on this item asks for confirmation:

Quit without saving (Y/N)? Y

This allows you to exit Setup without storing in CMOS any change. The previous selections remain in
effect. This exits the Setup utility and restarts your computer.

POST Messages

During the Power On Self-Test (POST), if the BIOS detects an error requiring you to do something to fix,
it will either sound a beep code or display a message.

If a message is displayed, it will be accompanied by:

PRESS F1 TO CONTINUE, CTRL-ALT-ESC OR DEL TO ENTER SETUP

POST Beep

Currently there are two kinds of beep codes in BIOS. This code indicates that a video error has occurred
and the BIOS cannot initialize the video screen to display any additional information. This beep code
consists of a single long beep followed by two short beeps. The other code indicates that your DRAM
error has occurred. This beep code consists of a single long beep repeatedly.
