Introduction

Welcome to the JUKI-752 DX4-100 with LCD/CRT Single Board
Computer. The JUKI-752 is an ISA with PC/104 form factor
board, which comes equipped with ACC Maple Chipset (includes
DX4-100 CPU) and advanced high-performance multi-mode I/O,
designed for the system manufacturers, integrators, or VARs that
want to provide all the performance, reliability, and quality at a
reasonable price.

An advanced high performance super I/O function are in the
Maple chipset too.. The in chip UARTs are compatible with the
NS16C550. The parallel port and IDE interface are compatible
with IBM PC/AT and XT architecture's, as well as EPP and ECP.

The LCD/CRT controller is HMC HM86508 which can provide the
LCD and CRT display at the same time. The LCD interface
connector is a 44-pin 2.0mm pitch type.

The most outstanding feature in the JUKI-752 is built-in PC/104
expansion bus. Based on the PC/104 bus, you could easily install
over thousands of PC/104 modules from hundreds' vendors in
the world. The JUKI-752 has external power connector that could
let it connects with power supply directly. It is more suitable for
your standalone applications.

The Watch-Dog Timer is enabled by reading port 443H. It should
be triggered before the time-out period ends, otherwise it will
assume the program operation is abnormal and will issue a reset
signal to start again, or activate NMI to CPU. The Watch-Dog
Timer is disable by reading port 843H. The Watch-Dog Timer
time-out period can be set 1,2,10,20,110 or 220 sec. by JP3.

AMI BIOS Setup

The JUKI-752 use AMI BIOS for system configuration, and the
AMI BIOS setup program is designed to provide maximum
flexibility in configuring the system by offering various options
which may be selected for end-user requirements. This chapter
is written to assist you in the proper usage of these features.

4.1 Getting Start

When the system is powered on, the BIOS will enter the Power­On-Self-Test routines. These routines will be executed for
System Test and Initialization and System Configuration
Verification. After the POST routines are completed, the
following message appears :

" Hit < Del>, if you want to run SETUP"

To access AMI BIOS Setup program, press <Del> key.

4.2 Standard CMOS Setup

Standard CMOS Setup is the first option on the main menu.
The standard CMOS setup utility is used to configure the
following features :

¡E

Date/Time,

¡E

Hard Disk Type,

¡E

Floppy Disk Type,
All of these features are almost the same as common, so we do
not describe more detailed in here.

Appendix A. Watch-Dog Timer

The Watch-Dog Timer is provided to ensure that standalone
systems can always recover from catastrophic conditions that
caused 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 either perform a hardware
reset (cold boot) or a non-maskable interrupt (NMI) to bring the
system back to a known state.

The Watch-Dog Timer is controlled by two I/O ports.

443
(hex)
843
(hex)

To enable the Watch-Dog Timer, a read from I/O port 443H must
be performed. This will enable and activate the countdown timer
which will eventually time out and either reset the CPU or cause
an NMI depending on the setting of JP4. To ensure that this reset
condition does not occur, the Watch-Dog Timer must be
periodically refreshed by reading the same I/O port 433H. This
must be done within the time out period that is selected by
jumper JP3.

A tolerance of at least 30% 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.

Read Enable the refresh the Watch-Dog

Timer.

Read Disable the Watch-Dog Timer.

19

Note:

when exiting a program it is necessary to disable the Watch-

Dog Timer, otherwise the system will reset.

Appendix B. Panel Support List

The JUKI-752 supports a wide range 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,customer
only need to re-program the BIOS flash chip with the file,then
power on again.

18MLCD.ROM – BIOS for MONO DSTN 640x480

For example : HOSIDEN HLM6667

HITACHI LMG5160XUFC
CASIO MD650TS00-01

For example : HITACHI TX26D60/TX24D55

TOSHIBA LTM09C015A
SHARP LQ10D321

18TFTLP1.ROM – BIOS for TFT 640x480-LP(16-bit)
18TFTLP2.ROM – BIOS for TFT 640x480-LP(16/24-bit)

For example : TOSHIBA LTM09C015A

18TFT861.ROM – BIOS for TFT 800x600-SYNC(16-bit)
18TFT862.ROM – BIOS for TFT 800x600-SYNC(18/24-bit)

For example : NEC NL8060AC26-05

NEC NL8060AC26-04
NEC NL8060BC31-02

18EL.ROM – BIOS for EL 640x480

For example : PLANAR EL640.480-A

18PLASMA.ROM – BIOS for PLASMA 640x480

For example : PANASONIC S817

How to update the BIOS by 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 (
program the BIOS under DOS.
For example :

C:>FLASH631 MLCD.ROM

FLASH631.COM

) and directly re-
