specification. The existing parallel port signals will be used by EPP to provide
asymmetric bi-directional data transfer driven by the host devices. ECP
passes the parallel port to be used with devices which stick to the ECP
specification.

• Parallel Port IRQ: To define the Interrupt Request (IRQ) which is used by the
parallel port.

• Parallel Port DMA Channel: To set the DMA Channel used by the parallel port.

4.6 Auto-Detect Hard Disk

This option detects the parameters of an IDE hard disk drive (HDD sector, cylinder,
head, etc) automatically and will put the parameters into the Standard CMOS
Setup screen. Up to 4 IDE drives can be detected and the parameters will be
listed in the box. Press <Y> if you accept these parameters. Press <N> to skip
the next IDE drives.

Note: If your IDE HDD was formatted in previous older system, incorrect
parameters may be detected. In this case, you need to enter the correct
parameters manually or low-level format the disk.

4.7 Change Supervisor Password

This option sets a password that is used to protect your system and Setup Utility.
Supervisor Password has higher priority than User Password. Once you setup the
password, the system will always ask you to key-in password every time you
enter the BIOS SETUP. If you enter the BIOS SETUP with Supervisor Password,
you can choose every setup/option on the main menu but with User Password,
you can only choose three setup/options (USER PASSWORD, SAVE SETTING AND
EXIT and EXIT WITHOUT SAVING). To disable these passwords, enter the BIOS
SETUP room with Supervisor Password and then just press the <Enter> key
instead of entering a new password when the 'Enter Password' prompt pops up.
N.B.: if you forget the password, do the Clear/Reset CMOS procedure (see Part

2.8 the CPU Setting for JUKI-750E >> Clear CMOS SETUP)

4.8 Auto Configuration with Optimal Settings

This option lets you load the optimal default settings. These settings are best­case values which will provide the best performance. Whenever your C MOS RAM

is damaged, these optimal settings will be loaded automatically.

4.9 Auto Configuration with Fail Safe Settings

This option lets you load the Fail Safe default settings when something happens
to your computer so that it cannot boot normally. These settings are not the
most optimal settings but are the most stable settings.

25

4.10 Save Settings and Exit

Select this option when you finish setting all the parameters and want to save
them into the CMOS. Just simply press <Enter> key and all the configuration
changes will be saved.

4.11 Exit Without Saving

Select this option if you want to exit the Setup without saving the changes that
you made. Just simply press <Enter> key and you will exit the BIOS SETUP
without saving the changes.

Appendix A Watchdog Timer

Watchdog Timer is provided 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 correctly, hardware on the board will perform a hardware reset (cold boot)
to bring the system back to a known state.

Watchdog Timer is controlled by three I/O ports.

543 Write Set Watchdog Time period
543 (hex) Read Enable the refresh the Watchdog Timer.
943 (hex) Read Disable the Watchdog Timer.

To enable the Watchdog Timer, user has to define Timer before enable the Watch­dog Timer function. 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 w ill eventually time out
and reset the CPU to ensure that this reset condition does not occur, the Watch­Dog Timer must be periodically refreshed by reading the same I/O port 943H and
543H. 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 543H
must be read within 7 seconds.

Note: when exiting a program it is necessary to disable the Watch-Dog Timer,
otherwise the system will reset.

Example program:
TIMER_PORT = 543H

TIMER_START = 543H
TIMER_STOP = 943H

Appendix B Panel Support List

The JUKI-750E supports a wide range of flat panels. The different flat panel will
need different LCD drive BIOS. The default setting is for Color DSTN flat panel.
The available BIOS for different panels are in the following list. Please note all
the BIOS files already included the system BIOS and LCD drive BIOS, re-program
the BIOS flash chip with the file, and then power on again.

How to update BIOS yourself?

1. Use EPROM Programmer setting the right Flash type and then write the file

into the Flash.

To use this method, you should carefully take the Flash chip out of socket and
then put it back after finish the programming.
Usually the flash type is: ATMEL AT29C010A

Or,

2. There also have a utility (FLASH462.COM) and directly re-program the BIOS

under DOS.

For example:
C:>FLASH462 15MLCD.ROM
