1. Introduction

- Slitless/fanless design that reduces maintenance work
This product's spindleless design eliminates the heat dissipating slit and CPU fan and adopts CF card for
the storage. It is free from dusts and foreign objects, and the use the parts that degrades over the years is
avoided in most case, resulting in drastic alleviation of the maintenance burden.

- Remote power management function to reduce operation tasks
This product supports timed/automated system start-up (Resume By Alarm). For example, it enables
unattended operation, such as starting to show information of an establishment in unison at opening time.
Also, it supports system start-up externally via network (Wake On LAN) and modem (Power On by Ring).
It encourages significant labor saving in operation.

- Major types of peripherals are supported with rich interfaces including the two CF card slots
It has a variety of extended interface such as 1000BASE-T x 2, USB2.0 x 4, serial (RS-232C) x 2.
It has 2 CF card slots that can use for OS and data. They are very useful because you can use one slot for
system start-up and the other for maintenance, system log, or taking away the collected data.

- Falling-off prevention tools and fixing clamps provided to avoid trouble caused by disconnected cable
This product stays trouble-free, being equipped with USB removal prevention fitting and cable clamp for
connectors with no locking mechanism, such as USB cable, and with hardware to properly mount and
avoid falling out of CF card.

- Safety design required for embedded applications
Retention of CMOS data by EEPROM allows the system to start up even when the battery has run out.

For Windows Embedded Standard installed model, it is possible to use the EWF*1 function of OS. It is
designed for safety required for embedding purpose, for example, prohibiting unwanted writing to the CF
card with EWF function will relieve the concern about the writing limits to the CF card and prevent an
unintentional system alteration.

*1 EWF (Enhanced Write Filter) is a function specific to Windows Embedded Standard that protects the disk from being actually written

by

redirecting the writing to RAM.

- A wide range of power supplies (10.8 - 31.2VDC) supported
As the product supports a wide range of power (10.8 - 31.2VDC), it can be used in a variety of power

environments. The separately available AC adapter adds support for 100VAC power.

(For information on the latest version of IPC-SLIB-01, check the CONTEC's Web site.)

- You need to set the screen resolution if the display cable is not connected to this DVI-D interface at
OS startup, but connected after OS startup (hereinafter referred to as “Late Insertion”). For more
details on this, refer to the CONTEC’s Web site [IPC-SLIB-01].

- You need to set the screen resolution against the analog interface. For more details on the setting
method, refer to the CONTEC’s Web site [IPC-SLIB-01].

- When using the DVI interface, resolution 640 x 480 may not be displayed normally. To display it
normally, you need to set the screen resolution. For more details on the setting method, refer to the
CONTEC’s Web site [IPC-SLIB-01].

- When the analog display is used, Windows MS-DOS may not be properly displayed in full-screen
mode.
This is because the frequency and resolution of Windows and MS-DOS (full-screen display) are the
same due to the screen settings while the display parameters are different.
For display, as only one parameter can be stored for one frequency or resolution, only either of
Windows or MS-DOS screen can be displayed properly.
In this case, change the resolution or display frequency of Windows so that it is not the same as for
the MS-DOS display.

5. BIOS Setup

5. 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

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.

Table 5.1. Using 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.

*1 About the CF Backup Feature
To use the CF Backup feature, a separately-available CF for backup is required. The CF for backup must be the CF of the same model

or larger capacity. Using the CF that is not our optional parts can be the cause of unidentified problems and it must be ensured that the
CF works with your system without problem before using this feature.
Also, before performing backup, read the licensing terms of your operating system carefully so that the backup is carried out within the
scope of given license.

Followings are the steps to use the CF Backup feature.
<Using the CF Backup Feature>

(1) Connect display and keyboard to the box computer.
(2) Insert the CF and the CF for backup to the respective CF slot before turning the power on.
(3) Press the “DEL” key before the startup to invoke the BIOS setting screen, and select “CF Backup” from menu.
(4) Follow the messages on the screen to proceed with the process. For the copy process, the Source Disk (the CF to be backed up)

and the Destination Disk (the CF for backup) must be specified. The contents of the Source Disk can be lost if the Disks are
wrongly assigned: ensure the correct operation by carefully reading the displayed message and performing the procedures
accordingly.

(5) When the backup process is finished, the message “BACKUP finish, Press any key reboot.” is displayed. Enter any one of the

46

alphabet keys from A to Z. The system reboots upon the key input.

(6) Backup completes when the above steps are done.

Description

Choices

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.

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 setup Defaults (Y/N) ? N

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

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

ENTER 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.

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. 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.

5. BIOS Setup

Exit Selecting

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.

Error Messages

One or more of the following messages may be displayed if the BIOS detects an error during the POST.
This list includes messages for both the ISA and the EISA BIOS.

CMOS battery has failed

CMOS battery is no longer functional. It should be replaced.

Disk boot failed
[INSERT SYSTEM DISK AND PRESS ENTER]

No boot device was found. This could mean that either a boot drive was not detected or the drive does not
contain proper system boot files. Make sure the connection of boot drive and its content.

Error encountered initializing hard drive

Disk drive cannot be initialized. Be sure all recording media such as HDD/SSD/CF are installed correctly.
Also be sure the correct hard drive type is selected in Setup.

Error initializing hard disk controller

Cannot initialize disk drive controller. Be sure all recording media such as HDD/SSD/CF are installed
correctly. Also be sure the correct hard drive type is selected in Setup.

Keyboard error or no keyboard present

Cannot initialize the keyboard. Make sure the keyboard is attached correctly and no keys are being
pressed during the boot.

If you are purposely configuring the system without a keyboard, set the error halt condition in Setup to
HALT ON ALL, BUT KEYBOARD. This will cause the BIOS to ignore the missing keyboard and
continue the boot.

Memory address error at…

Indicates a memory address error at a specific location.

Press a key to REBOOT

This will be displayed at the bottom screen when an error occurs that requires you to reboot.

Press F1 to disable NMI, F2 to REBOOT

When BIOS detects a Non-maskable Interrupt condition during boot, this will allow you to disable the
NMI and continue to boot, or you can reboot the system with the NMI enabled.

System halted, (CTRL-ALT-DEL) to REBOOT…

Indicates the present boot attempt has been aborted and the system must be rebooted. Press and hold
down the CTRL and ALT keys and press DEL.
