Introduction

Welcome to the NOVA-300 Embedded 386SX SBC. The NOVA-

300 is an with PC/104 form factor board, which comes equipped

with ALI 6117 (includes 386SX 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 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.

1.2 What You Have

In addition to this User's Manual, the NOVA-300 package

includes the following items:

•NOVA-300 Embedded 386SX SBC

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.

2.1 NOVA-300's Layout

< reference next page >

2.2 CPU Setting for NOVA-300

•CPU SPEED SETTING:

The system clock is generated by the AV9155C-02, and the

different CPU clock frequency can be selected by JP3 and

shown as following table:

JP3 1-2 3-4 5-6

8MHz OPEN CLOSE CLOSE

16Mhz CLOSE OPEN CLOSE

20MHz OPEN OPEN CLOSE

25MHz CLOSE CLOSE OPEN

40MHz CLOSE OPEN OPEN

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.

•JP1/JP2 : 4MB DRAM and 72-pin SIMM selection

Function JP1 JP2

On Board 4MB CLOSE CLOSE

72-pin SIMM OPEN OPEN

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

JP16.

•JP18 : Watch-Dog Active Type Setting
