1. Manual Objectives
This manual describes in detail the Evalue Technology ECB-862 Single Board.
We have tried to include as much information as possible but we have not duplicated
information that is provided in the standard IBM Technical References, unless it proved to
be necessary to aid in the understanding of this board. The manual is sectioned and
includes a User’s Guide that will help the non-technical user to get the unit up and running.
A Troubleshooting Guide is also included to help when things go wrong.
We strongly recommend that you study this manual carefully before attempting to interface
with ECB-862 or change the standard configurations. Whilst all the necessary information
is available in this manual we would recommend that unless you are confident, you contact
your supplier for guidance.
Please be aware that it is possible to create configurations within the CMOS RAM that
make booting impossible. If this should happen, clear the CMOS settings, (see the
description of the Jumper Settings for details).
If you have any suggestions or find any errors concerning this manual and want to inform
us of these, please contact our Customer Service department with the relevant details.

3.8 Setting Jumpers
You can configure your board to match the needs of your application by setting jumpers. A
jumper is the simplest kind of electric switch.
It consists of two metal pins and a small metal clip (often protected by a plastic cover) that
slides over the pins to connect them. To “close” a jumper you connect the pins with the clip.
To “open” a jumper you remove the clip. Sometimes a jumper will have three pins, labeled
1, 2, and 3. In this case, you would connect either two pins.
The jumper settings are schematically depicted in this manual as follows:
A pair of needle-nose pliers may be helpful when working with jumpers.
If you have any doubts about the best hardware configuration for your application, contact
your local distributor or sales representative before you make any changes.

4. Award BIOS Setup
4.1 Starting Setup
The AwardBIOS™ 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:
By pressing <Del> immediately after switching the system on, or
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

4.3 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.
4.4 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.
4.5 Main Menu
Once you enter the AwardBIOS™ CMOS Setup Utility, the Main Menu will appear on the
screen. The Main Menu allows you to select from several setup functions and two exit
choices. Use the arrow keys to select among the items and press <Enter> to accept and
enter the sub-menu.

Note:
It is strongly recommended to reload Optimized setting if CMOS is lost or BIOS is
updated.

4.5.4 Advanced Chipset Setup Defaults
This Setup is very important to keep system’s stability. If you are not technical person, do
not attempt to change any parameters. The best way is to choose optimal default setting.
Figure 4: The Advanced Chipset Features
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.
The first chipset settings deal with CPU access to dynamic random access memory
(DRAM). The default timings have been carefully chosen and should only be altered if
data is being lost. Such a scenario might well occur if your system had mixed speed
DRAM chips installed so that greater delays may be required to preserve the integrity of
the data held in the slower memory chips.

Appendix C: AWARD BIOS 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.
CMOS Checksum Error
Checksum of CMOS is incorrect. This can indicate that CMOS has become corrupt. This
error may have been caused by a weak battery. Check the battery and replace if
necessary.
Disk Boot Failure, 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. Insert a system disk into Drive A: and
press <Enter>. If you assumed the system would boot from the hard drive, make sure the
controller is inserted correctly and all cables are properly attached. Also be sure the disk is
formatted as a boot device. Then reboot the system.
Diskette Drives Or Types Mismatch Error – Run Setup
Type of diskette drive installed in the system is different from the CMOS definition. Run
Setup to reconfigure the drive type correctly.
ECB-862/862L User’s Manual 93
User’s Manual
Display Switch Is Set Incorrectly
Display switch on the motherboard can be set to either monochrome or color. This
indicates the switch is set to a different setting than indicated in Setup. Determine which
setting is correct, and then either turn off the system and change the jumper, or enter
Setup and change the VIDEO selection.
Display Type Has Changed Since Last Boot
Since last powering off the system, the display adapter has been changed. You must
configure the system for the new display type.
EISA Configuration Checksum Error
Please Run EISA Configuration Utility
The EISA non-volatile RAM checksum is incorrect or cannot correctly read the EISA slot.
This can indicate either the EISA non-volatile memory has become corrupt or the slot has
been configured incorrectly. Also be sure the card is installed firmly in the slot.
EISA Configuration Is Not Complete
Please Run EISA Configuration Utility
The slot configuration information stored in the EISA non-volatile memory is incomplete.
Note: When either of these errors appear, the system will boot in ISA mode, which allows you to run the
EISA Configuration Utility.
Error Encountered initializing Hard Drive
Hard drive cannot be initialized. Be sure the adapter is installed correctly and all cables are
correctly and firmly attached. Also be sure the correct hard drive type is selected in Setup.
Error Initializing Hard Disk Controller
Cannot initialize controller. Make sure the cord is correctly and firmly installed in the bus.
Be sure the correct hard drive type is selected in Setup. Also check to see if any jumper
needs to be set correctly on the hard drive.
Floppy Disk Cntrlr Error Or No Cntrlr Present
Cannot find or initialize the floppy drive controller. Make sure the controller is installed
correctly and firmly. If there are no floppy drives installed, be sure the Diskette Drive
selection in Setup is set to NONE.

Invalid EISA Configuration
Please Run EISA Configuration Utility
The non-volatile memory containing EISA configuration information was programmed
incorrectly or has become corrupt. Re-run EISA configuration utility to correctly program
the memory.
NOTE: When this error appears, the system will boot in ISA mode, which allows you to run the EISA
Configuration Utility.
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. You can use this location along
with the memory map for your system to find and replace the bad memory chips.
Memory Parity Error At...
Indicates a memory parity error at a specific location. You can use this location along with
the memory map for your system to find and replace the bad memory chips.
Memory Size Has Changed Since Last Boot
Memory has been added or removed since the last boot. In EISA mode use Configuration
Utility to reconfigure the memory configuration. In ISA mode enter Setup and enter the
new memory size in the memory fields.
Memory Verify Error At...
Indicates an error verifying a value already written to memory. Use the location along with
your system's memory map to locate the bad chip.
Offending Address Not Found
This message is used in conjunction with the I/O CHANNEL CHECK and RAM PARITY
