* Component life is not guaranteed value but only referential value.

The backup time at a temperature of 25°C with the power disconnected is 10 years.

The NandFlash can be rewritten 60,000 times or more.

As a reference value, the rewritable lifetime can be determined by the following
calculation.

Rewritable lifetime (number of times) = ((capacity [MB] / management block size

[MB]) × 60,000 times) / (number of management blocks rewritten each time)
Example: If a 4 MB file is created and is rewritten once every 10 seconds
Rewritable lifetime = ((3577/2) × 60000)) / 2 = 53,655,000 (number of times)

≒

Lifetime = 53,655,000 / ((60/10) × 60 × 24 × 365)

Introduction

This chapter discusses AMI’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 FLASH
ROM 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 BIOS is immediately activated when you first power on the computer. The BIOS reads the system
information contained in the FLASH ROM 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> or <F2> immediately after switching the system on, or
2 By pressing the <Del> or <F2> key when the following message appears briefly at the bottom of

the screen during the POST (Power On Self-Test).

Press <DEL> or <F2> 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. You may also restart by simultaneously pressing <Ctrl>, <Alt>, and
<Delete> keys.

CAUTION

For the Windows Embedded Standard 7 model (BX-955SD-DC6312), the BIOS SETUP screen

may not be displayed when some RGB displays are connected. In this situation, set "Boot Display
Type" to "CRT" on the "Intel IGD Configuration" menu.

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 it is not possible to boot the computer after system settings have been changed and saved during setup,
this product will need to be repaired.

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 AMI and your systems manufacturer to provide the absolute maximum
performance and reliability. If chipset settings are changed even slightly, it may become necessary to
repair the unit.

A Final Note About Setup

The information in this chapter is subject to change without notice.

Baud Rate Settings
A baud rate is set by software by dividing the clock input (1.8432MHz). The baud rate in terms of

hardware can be set to a maximum of 115,200 bps for SERIAL A, B, C, D. The baud rates available in
practice depend on the operating environment (cable, software, etc.). The table below lists typical baud
rates and their respective values to be written to the divisor latch register (LSB, MSB).

Watch-Dog-Timer

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. To maintain the
normal system operation, trigger the timer periodically by the user-created program in consideration of
the tolerance.

Ex.) If the time-out interval is set to 30 seconds, the user-created program must retrigger the watchdog

timer before 28 seconds will have elapsed in consideration of the tolerance. If the program failed to
retrigger the timer (if 28 - 32 seconds have elapsed), the system will automatically reboot.

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.

* It is also possible not to perform [WDT Stop] instead of performing [WDT Stop] to [WDT Start], but to perform

}

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

No

END

If [WDT Stop] is not performed within the limit time set up
by [WDT Start], system reset occurs.
