AMI Setup program enables 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.
4.2 Starting Setup
AMI BIOS will be activated immediately when you first power on the
computer. BIOS reads the system information contained in CMOS
and begins the process of checking out the system and configuring it.
When the process is completed, BIOS will seek an operating system
on one of the disks and then launch and turn control over to the
operating system.
When 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 <Del> 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, restart the system to try again by turning it OFF. Then
turn ON the system or press the "RESET" button on the system case.
You may also restart the system 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 F2 TO CONTINUE, DEL TO ENTER SETUP
26
4.3 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 details about how to navigate in the Setup program
using the keyboard.
Up arrow Move to the previous item
Down arrow Move to the next item
Left arrow Move to the item on the left
Right arrow Move to the item on the right
Esc key Main Menu— Quit and not save changes into CMOS
Status Page Setup Menu and Option Page Setup
Menu— Exit current page and return to Main Menu
PgUp key Increase the numeric value or make changes
PgDn key Decrease the numeric value or make changes
+ key Increase the numeric value or make changes
- key Decrease the numeric value or make changes
F1 key General help, only for Status Page Setup Menu and
Option Page Setup Menu
F2 /F3 key Change color from total 16 colors. F2 to select

Press F1, a help window will pop and describe 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.
If you discover that your computer is no longer able to boot after
making and saving system changes with Setup, AMI BIOS supports
an override to the CMOS settings which resets your system to its
defaults.
It is strongly recommended that you should avoid making any
changes to the chipset defaults. Otherwise, it may cause system
malfunction.

Type the password of up to eight characters in length, and press
<Enter>. Previous password will be cleared from CMOS memory.
Confirm the new password and press <Enter>. To quit, press
<Esc>.
To disable a password, press <Enter> when you are prompted to
enter the password. A message will ask you to confirm disabling the
password. Once the password is disabled, the system will boot and
you can enter Setup freely.
PASSWORD DISABLED:
When a password is 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. 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 (see Section 3). If the
Security option is set to “Always”, a password will be required both
at boot and at entry to Setup. If set to “Setup”, prompting will only
occur when trying to enter Setup.

Appendix A: Watchdog Timer
The Watchdog Timer is a device to ensure that standalone systems can always
recover from abnormal conditions that system crash. These conditions may
result from an external EMI or a software bug. When the system stops working,
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 operation of Watchdog Timer:
443 (hex) Write Set Watchdog Time period
443 (hex) Read Enable Watchdog Timer
043/843 (hex) Read Disable Watchdog Timer
Prior to enable Watchdog Timer, users have to set the time-out period. The
resolution of the timer is 1 second and the range of the timer is from 1 second to
255 seconds. You need to send the time-out value to the I/O port— 443H, and
then enable it by reading data from the same I/O port— 443H. This will activate
the timer that will eventually time out and reset the CPU board. To ensure that
this reset condition won’t occur, Watchdog Timer must be periodically refreshed
by reading the same I/O port 443H. This must be done within the time-out
period that is set by the software, please refer to the example program. Finally,
we have to disable the Watchdog Timer by reading the I/O port— 843H or 043H.
Otherwise the system could reset unconditionally.
A tolerance of at least 5% must be maintained to avoid unk nown routines in the
operating system (DOS). For example, if the time-out period has been set to 10
seconds, the I/O port 443H must be read within 7 seconds.

Appendix C: How to Use Wake-up Function
JUKI-EDEN/C3 provides two kinds of Wake-up function. This page describes how
to use Modem Wake-Up and LAN Wake-Up functions. Wake-Up function only
works with ATX power supply.
Wake-Up On Modem (Ring):
You must set the option Wake-Up On LAN/Ring of CMOS SETUP to be enabled.
ATX power supply will be switched on when there is a ring signal detect ed on pin
“RI” of serial port.
Wake-Up On LAN:
When your computer is in power-down status, LAN Link/Active LED will flash.
This indicates that the LAN chip has entered standby mode and is waiting for
Wake-Up signal. You can use other computers to wake up yours by sending ID to
it.
ID: ID is the MAC address of your system LAN. Every LAN chip has a factory-set
ID, which you can find it from network information in Windows.
ID’s format is xxxxxxxxxxxx
Example ID: 009027388320

Appendix D: Digital I/O
One of digital circuit’s characteristics is its fast response to high or low signal.
This kind of response is highly needed for harsh and critical industrial operat ing
environment. Therefore, JUKI-EDEN/C3 is designed with 4-bit digital inputs and
4-bit digital outputs.
There are two kinds of signals (Input and Output) used by the Digital I/O function.
These signals are used to control external devices that need On/Off circuit or TTL
devices. When one of the signals has been selected, users can read or write data
to the system through the Digital I/O function.
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 as 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 as 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 ;
