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.

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
