1. Introduction

Thank you for choosing JUKI-730 386SX with LCD/CRT/4COM
Single Board Computer. The JUKI-730 is an ISA with PC/104 form
factor board, which comes equipped with ALI 6117 (386SX CPU
included) and an 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 AT I/O chip Windbond
W83877F and SMC FDC37C669 are used in the JUKI -730 board.
Both on-chip UARTs are compatible with the NS16C550 and one
COM port can be set in RS232, RS422, or RS485. The parallel port
and IDE interface are compatible with IBM PC/AT and XT
architectures, as well as EPP and ECP.

The LCD/CRT controller is TOPRO TP-6508, which can provide
both 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-730 is the built-in
PC/104 expansion bus. Based on the PC/104 bus, you could easily
install over thousands of PC/104 modules manufactured by
hundreds of vendors worldwide. Aside from that, the JUKI-730
has an external power connector that allows direct connection to
a power supply making it more suitable for your standalone
applications.

layout of JUKI-730 is shown, and then the unpacking
information that you should be careful with is described.
After that comes the setting for jumpers and switches for the
JUKI-730's configuration, with information such as CPU type
selection, system clock setting, and interrupt IRQ setting for
serial ports and parallel port and other such settings.

2.3 System Memory

The system DRAM on board is divided into two banks, bank 0
and 1. Bank 0 is the on board optional 2/4MB DRAM. Bank 1 is
a 72-pin SIMM. Based on the chipset function the 72-pin SIMM
only supports single side DRAM. There are two jumpers
related to this setting.

2.4 Watch-Dog Timer

The Watch-Dog Timer is enabled through reading port 443H.
It should be triggered before time-out period ends, otherwise
it will assume that program operation is abnormal and will
issue a reset signal to start again, or activate NMI to CPU. The
Watch-Dog Timer can be disabled through reading port 043H.
The Watch-Dog Timer time-out period can be set
1,2,10,20,110 or 220 sec. using jumper JP16.

4. AMI BIOS Setup

The JUKI-730 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 to fit end-users’ individual demands . This chapter is written
to demonstrate how you can use these features properly.

4.1 Getting Start

When the system is powered on, the BIOS will enter the
Power-On-Self-Test routines. These routines will be executed for
System Tes t, 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 CM OS Setup is the first option on the main menu.
The standard CMOS setup utility is used to configure the following
features:

•Date/Time

•Hard Disk Type

•Floppy Disk Type

All of these features are very commonly seen so we here do not
describe in detail.

25

4.3 Advanced CMOS Setup

After you enter the Advanced CMOS Setup you will see that this
Setup program is equipped with a series of help screens, accessed
through pressing <F1> key, which will display the options available for
a particular configuration feat ures.

All the items on the left side of the screen are very common so they
will not be mentioned within this manual. Here, we will focus on some
special items that are only found in JUKI-730. These items are
specified below:

•

On-board IDE Controller : The IDE hard disk drive can be

Enable or Disable through this item. When

you do not need the hard disk, the IDE
controller can be disabled.

•

On-board Floppy Controller : The floppy disk drive can be

Enable or Disable through this item. When
you do not need floppy disk, the FDD
controller can be disabled.

•

Serial Port 1 : The options are Disable, 3E8,2F8 ,or 3F8.

You can either set the I/O address of the
serial port (COMA) or disable it.

•

Serial Port 2 : The options are Disable, 2E8,3F8,or 2F8.

You can either set the I/O address of the
serial port 1 (COMB) or disable it.

•

Parallel Port : The options are Disable, 3BC, 378 or 278.

You can either set the I/O address of the
parallel port or disable it.

•

Parallel Port Mode : JUKI-730 provides

EPP,ECP,ECP+EPP, and Normal Mode.

•

Primary Display : You could set VGA/EGA, CGA40x25,

CGA80x25, Mono or Absent. When

configured to Absent, JUKI-730 will not
check the display adapter while powering on
the system.

26

•

System Keyboard : You could set Present or Absent.

When set Absent , JUKI-730 board will not
check the display adapter while powering on
the system.

27

Appendix A. E2 Key™ Function

The JUKI-730 provides an outstanding E2KEY™ function for
system integrator. Based on the E2KEY™ you could free to store
the ID Code, Pass Word, or Critical Data in the 1Kbit EEPROM.
Because the EEPROM is a nonvolatile memory, you don’t have to
worry about losing very important data.

Basically the E2KEY™ is based on a 1Kbit EEPROM, which is
configured to 64 words (from 0 to 63). You could access (read or
write) each word anytime.

When you need to use E2KEY™ please find the utility enclosed in
the package. The software utility will include the following four
files

README.DOC
E2KEY.OBJ
EKEYDEMO.C
EKEYDEMO.EXE.

E2KEY.OBJ provides two library function for user to integrate their
application using E2KEY™ function. These libraries (read_e2key
and write_e2key) are written and compiled in C format. For
easy implementation, please refer to the following statement s.

unsigned int read_e2key(unsigned int address)

/* This function will return the E2KEY™’s data at address. The address range is

from 0 to 63. Return data is one word, 16 bits */

void write_e2key(unsigned int address,unsigned data)

/* This function will write the given data to E2KEY™ at address. The address range

is from 0 to 63. The data value is from 0 to 0xffff. */

For easy start, please refer to the included EKEYDEMO.C code first.

28

Please note the E2KEY™ function is based on the working of
parallel port. So you should enable the JUKI-730’s parallel port,
otherwise will not be working.

29

Appendix B. Watch-Dog Timer

The Watch-Dog Timer is provided to ensure that standalone
systems can always recover from catastro phic 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)
043
(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 a reset action of the
CPU or cause an NMI will occur depending on the setting of JP18.
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 JP16.

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.

Note: When exiting a program, it is necessary to disable the

Appendix D. How to Update the BIOS

1. You can use EPROM Programmer setting to configure the
right type of Flash then write the file into the Flash. To apply
this method, you should carefully take Flash chip out of
socket and then put it back after you finish programming.
Most commonly seen flash type is: ATMEL AT29C010A

Or,

2. There is also a utility (FLASH634.COM) that can be used to
re-program the BIOS directly under DOS environment .

For example:
C:>FLASH634 MLCD.ROM
