Introduction

Welcome to the NOVA-300 Embedded 386SX SBC. The NOVA­300 is an with PC/104 form factor board, which comes equipped
with ALI 6117 (includes 386SX CPU) and advanced high­performance 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 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 NOVA-300 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 NOVA-300 has external power
connector that could let it connects with power supply directly. It
is more suitable for your standalone applications.

Installation

This chapter describes how to install the NOVA-300. At first, the
layout of NOVA-300 is shown, and the unpacking information
that you should be careful is described. The jumpers and
switches setting for the NOVA-300's configuration, such as CPU
type selection, system clock setting, and interrupt IRQ setting for
serial ports and parallel port, are also included.

2.3 System Memory DRAM

The system DRAM on board is divided into two banks, bank 0
and 1. The Bank 0 is the on board optional 4MB DRAM. Bank 1
is the one 72-pin SIMM. Based on the chipset function the 72-pin
SIMM only support single side 16-bit DRAM. There have two
jumpers for the related setting.

2.4 Watch-Dog Timer

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 043H. The Watch-Dog Timer
time-out period can be set 1,2,10,20,110 or 220 sec. by jumper

AMI BIOS Setup

The NOVA-300 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.

4.3 Advanced CMOS Setup

When you enter the Advanced CMOS Setup, this Setup program
is equipped with a series of help screens, accessed by <F1> key,
which will display the options available for a particular
configuration features.

21

All the items on the left side of the screen are very common,
they will not be mentioned here. Here, we just focus on some
special items which are in NOVA-300 board only. These items
are specified as following :

¡E

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

Appendix A. E2 Key™ Function

The NOVA-300 provides an outstanding E2KEY™ function for
system integrator. Based on the E2KEY™ you could free to store

22

the ID Code, Pass Word, or Critical Data in the 1Kbit EEPROM.
Because the EEPROM is nonvolatile memory, you don’ t have to
worry the losing of the 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 at any time.

When you start to use the E2KEY™ you should have the utility in
the package. The software utility will include four files as follows,

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

The E2KEY.OBJ provides two library function for user to
integrate their application with E2KEY™ function. These library

(read_e2key and write_e2key)

format. Please check the following statement, then you will know
how to implement it easily.

are written and compiled in C

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. */

To easy start to use the function, please refer the include
EKEYDEMO.C code at first.

Please note the E2KEY™ function is based on the working of
parallel port. So you should enable the NOVA-300’ s parallel port,
otherwise will be not working.

23

If you need Windows NT or 95 driver,then please down load the
driver from ftp.icpacquire.com.tw server.

Appendix B. 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.

24

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 reset the CPU or
cause an NMI 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 Watch-

Dog Timer, otherwise the system will reset.

Read Enable the refresh the Watch-Dog

Timer.

Read Disable the Watch-Dog Timer.

Appendix C. Panel Support List

The NOVA-300 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

25

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,
