6. Watch-Dog-Timer (WDT) Setting
Introduction
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.
With the watchdog timer enabled, a RESET can be automatically generated unless the CPU periodically
triggers the timer within the 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 2e/2fH. You can trigger/enable disable the timer by writing
port2e/2fH.
Here is an example for flow chart and programming how to use the watch-dog-timer.

8. 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
battery-backed 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 finishes, 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

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.

Spread Spectrum
When the system clock generator pulses, the extreme values
of the pulse generate excess EMI. Enabling pulse spectrum
spread modulation changes the extreme values from spikes
to flat curves, thus reducing EMI. This benefit may in
some cases be outweighed by problems with timing-critical
devices, such as a clock-sensitive SCSI device.

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.
PASSWORD DISABLED.
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.
