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 2e/2fH. You can trigger/enable disable the timer by writing address
2e/2fH.
Here is an example for flow chart and programming how to use the watch-dog-timer.

When performing the re-start of WDT, it repeats [WDT Start] and [WDT Stop].

8. BIOS Setup
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 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 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

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.

This section allows you to configure the system based on the specific features of the installed chipset.
This chipset manages bus speeds and access to system memory resources, such as DRAM and the
external cache. It also coordinates communications between the conventional ISA bus and the PCI bus. It
must be stated that these items should never need to be altered. The default settings have been chosen
because they provide the best operating conditions for your system. The only time you might consider
making any changes would be if you discovered that data was being lost while using your system.

Select the precharge delay timer.
DRAM RAS# to CAS# delay
This field lets you insert a timing delay between
the CAS and RAS strobe signals, used when
DRAM is written to, read from, or refreshed.
Fast gives faster performance; and Slow gives
more stable performance. This field applies only
when synchronous DRAM is installed in the
system.
DRAM RAS# Precharge
The precharge time is the number of cycles it
takes for the RAS to accumulate its charge
before DRAM refresh. If insufficient time is
allowed, refresh may be incomplete and the
DRAM may fail to retain data.
