2.2 Unpacking Precautions
Some components of WAFER-C400EV SBC are very sensitive to static electric
charges and can be damaged by a sudden rush of power. To protect it from
unintended damage, be sure to note these precautions:
1. Ground yourself to remove any static charge before touching the
WAFER-C400EV SBC. You can do it by using a grounded wrist strap at all
times or by frequently touching any conducting materials that is connected
to the ground.
2. Handle WAFER-C400EV SBC by its edges. Don’t touch IC chips, leads or
circuitry if not necessary.
3. Do not plug any connector or jumper while the power is on.
2.3 System Memory DRAM
There is one 144-pin SO-DIMM socket to accept 3.3V non-buffered SDRAM. The
max Memory size is 512MB.
2.4 Watch-Dog Timer Setting
Reading port 443H enables the Watchdog Timer. It should be triggered before the
time-out period ends, otherwise it will assume th e program operation is abnormal
and will issue a reset signal to start again. Reading port 043/843H disables the
Watchdog Timer. Please refer to Appendix A for detailed information.
2.5 Clear CMOS Setup
If the user needs to clear the CMOS setup (for example, the user forgot the
password, then the setup should be cleared and the password should be re-set).
The user should short the JP1 about 3 seconds, and then open it again. Opening
JP1 can set the system back to normal operation mode.

Chapter 4 AMI BIOS Setup
4.1 Introduction
This chapter discusses AMI's setup program built into the 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.
4.2 Starting Setup
The AMI BIOS is immediately activated when you first boot up the computer. The
BIOS reads the system information contained in the CMOS and begins the process
of checking out the system and then configur es it. When it finishes, the BIOS will
seek an operating system on one of the disks and then launch and pass the
control over to the operating system.
While the BIOS is in charge, the Setup program can be activated in one of the
following 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.
Press DEL to enter SETUP.
If the message disappears before you respond and you still wish to enter Setup,
press the “RESET” button on the chassis or turn the power off then turn it back
on to restart the system then you can try again. You may also restart by
simultaneously pressing <Ctrl>, <Alt>, an d <Delete> keys. If you do not press
the keys at the correct moment and the system does not boot, an error message
will be displayed and you will again be asked to...
PRESS F1 TO ENTER SETUP OR PRESS F2 TO CONTINUE
23
4.3 Using Setup
In general, use the arrow keys to highlight options, 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.

If, after making and saving system changes with Setup, you discover that your
computer is no longer able to boot, the AMI BIOS supports an override to the
CMOS settings which can reset your system to its defaults.
The best advice is to alter only the settings which you thoroughly understand. To
this end, we strongly recommend not to make any changes to the chipset defaults.
These defaults have been carefully chosen by both AMI and the system
manufacturer to provide the optimum performance and reliability. Even a
seemingly little change to the chipset setup may shut the system down and need
the override program to reset it.

Enhanced Parallel Port(EPP) specification. EPP uses the existing
parallel port signals to provide asymmetric bidirectional data
transfer driven by the host device.
ECP: The parallel port can be used with devices that adhere to the
Extended Capabilities Port (ECP) specification. ECP uses the
DMA protocol to achieve data transfer rates up to 2.5 Megabits
per second. ECP provides symmetric bi-directional
communication.

4.13 Change Supervisor Password
You can set passwords for either supervisor or user password, or for both of them.
The differences between them are:
Supervisor Password:
It’s used to enter and change the settings of the setup menus.
User Password:
It’s used to only access the setup menus, but can’t change anything of it.
When you select this option, 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 existing password within CMOS
memory. You will be prompted to confirm the password. Type the password
again and press <Enter>. You may also press <Esc> to abort the selection
and not to enter a password.
To disable a password, just press <Enter> when you are prompted to enter
the password. A message which ask you to 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 user from
changing any bit of your system configuration.
Additionally, when a password is enabled, you can also require the BIOS to
request a password every time the system is booting. This would prevent
unauthorized uses of your computer.
The user can determine whether the password is needed for entering BIOS
Setup Program or other Security options (see Section 4.5). Once the
Password has been set, The user will be prompted to enter the password at
the beginning of booting and at the entry to Setup Menu.
39
Appendix A Watchdog Timer
The Watchdog Timer is a device to ensure that standalone systems can always
recover from catastrophic conditions that cause the CPU to crash. This condition
may have occurred by external EMI or a software bug. When the CPU stops
working normally, hardware on the board will perform hardware reset (cold boot)
to bring the system back to a known state.
Three I/O ports control the Watchdog Timer:
443 Write Set Watchdog Time period
443 (hex) Read Enable the refresh the Watchdog Timer
043/843 (hex) Read Disable the Watchdog Timer
Prior to enable the Watchdog Timer, user has to define Timer first. The output
data is a value of time interval and the range of the value is from 01(hex) to FF
(hex) and time interval 1 sec to 255 sec.
DATA TIME INTERVAL
01 1 sec
02 2 sec
03 3 sec
04 4 sec
- - - -
FF 255 sec
This will enable and activate the countdown timer which eventually t ime out and
reset the CPU to ensure that this reset condition does not occur; the Watch-Dog
Timer must be periodically refreshed by reading the same I/O port 043/843H
and 443H. This must be done within the time out period that is selected by
software, please refer to the example program.
A tolerance of at least 5% must be maintained to avoid unknown routines within
the operating system (DOS), such as disk I/O that can be very time consuming.
Therefore if the time-out period has been set to 10 seconds, the I/O port 443H
must be read within 7 seconds.
Note: When exiting a program it is necessary to disable the Watchdog Timer,
otherwise the system will reset.

Appendix B Digital I/O
One characteristic of digital circuit is its fast response to high or low signal. This
kind of response is highly needed for harsh and critical industrial operating
environment. That’s why we design 4-bit digital inputs and 4-bit digital outputs
on the WAFER-C400EV.
Digital Input and Output, generally, are control signals. You can use these signals
to control external devices that needs On/Off circuit or TTL devices. You can read
or write data to the selected address to enable the function of digital IO.
A BIOS function call (INT 15H) is used to control the Watchdog Timer:
INT 15H:
AH – 6FH
Sub-function:
AL – 8 : Set the Digital port is INPUT
AL : Digital I/O input value
Example Program:
MOV AX, 6F08H ;setting the Digital port is input
INT 15H ;
AL low byte = value
AH – 6FH
Sub-function:
AL – 9 : Set the Digital port is OUTPUT
BL : Digital I/O output value
Example program:
MOV AX, 6F09H ;setting the Digital port is output
MOV BL, 09H ;Digital value is 09H
INT 15H ;Digital Output is 1001b
