1 Introduction
Thank you for choosing JUKI-752 DX4-100 with LCD/CRT Single Board Computer.
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 is also in the Maple chipset.
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 TOPRO TP6508 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. JUKI-752 has external power
connector that can be connected to power supply directly. It is more suitable for
your standalone applications.

4 AMI BIOS Setup
JUKI-752 uses AMI BIOS for system configuration. 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 Started
When the system is powered on, BIOS will enter the Power-On-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:
- Date/Time
- Hard Disk Type
- Floppy Disk Type
All of these features are almost the same as common, so we do not describe
more detailed in here.
4.3 Peripheral CMOS Setup
When you enter Advanced CMOS Setup, the following settings will be shown,
• On-board IDE: The IDE hard disk drive can be Enabled or Disabled by this
item. When you do not need hard disk, the IDE controller can be disabled.
• On-board FDC: The floppy disk drive can be Enabled or Disabled by this
item. When you do not need floppy disk, the FDD controller can be disabled.
• Serial Port 1: The options are Disabled, 3E8, 2F8, or 3F8. You can set the
I/O address of the serial port (COMA) or disable it.
• Serial Port 2: The options are Disabled, 2E8, 3F8, or 2F8. You can set the
I/O address of the serial port 1 (COMB) or disable it.
• Parallel Port: The options are Disabled, 3BC, 378 or 278. You can set the
I/O address of the parallel port or disable it.
• Parallel Port Mode: JUKI-752 provides EPP, ECP, ECP+EPP, and Normal Mode.

17
Appendix A Watchdog Timer
Watchdog 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.
Watchdog Timer is controlled by two I/O ports.
443 (hex) Read Enable the refresh the Watchdog Timer.
843 (hex) Read Disable the Watchdog Timer.
To enable Watchdog 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 Watchdog 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.
Note: Disable Watchdog Timer when exiting a program, otherwise the system will
reset.

Appendix B Panel Support List
JUKI-752 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, customer only
need to re-program the BIOS flash chip with the file, and then power on again.
18MLCD.ROM – BIOS for MONO DSTN 640x480
For example: HOSIDEN HLM6667
HITACHI LMG5160XUFC
CASIO MD650TS00-01
OPTREX DMF_50260NFU-FW-8
18DSTN.ROM – BIOS for Color DSTN 640x480
For example: SANYO LCM-5331-22NTK
SHARP LM64C35P
18TFTS1.ROM – BIOS for TFT 640x480-SYNC (16-bit)
18TFTS2.ROM – BIOS for TFT 640x480-SYNC (18/24-bit)
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 (FLASH631.COM) and directly re-program the BIOS
under DOS. For example: C:>FLASH631 MLCD.ROM
