1. Introduction

Welcome to the ROCKY-328E 386SX with Ethernet Single
Board Computer. The ROCKY-328E is an ISA 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 SMC
FDC37C669 or equivalent chip is used in the ROCKY-328E
board. The UART is 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
FDC37C669 incorporates sophisticated power control
circuitry(PCC). The PCC supports multiple low power down
modes.

The most outstanding feature in the ROCKY-328E is built­in 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 ROCKY-328E
has external power connector that could let it connects
with power supply directly. It is more suitable for your
standalone applications.

In addition, the ROCK-328E provides one 72-pin SIMM
( Single In-line Memory Module) socket to install max.
32MB memory(single side RAM). The board also designed
4MB DRAM on board for OEM customer.

2.3 System Memory DRAM

The system DRAM on board is divided into two banks,
bank 0 and 1. Bank 0 is the on board optional 2/4MB
DRAM while Bank 1 is the one 72-pin SIMM. Based on
chipset function, the 72-pin SIMM only support single side
DRAM. There have two jumpers related to this 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
else 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 JP9.

already become an industrial embedded PC bus standard
so you could easily install over thousands of PC/104
modules from hundreds of venders worldwide.

NOTE : ROCKY-328E allows directly plug in PC/104

module, so you don‘t need the PC/104
Connection Kit.

4. AMI BIOS Setup

The ROCKY-328E 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 guide through
proper use of these features.

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 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 commonly seen so we won’t
elaborate on these items in this menu.

4.3 Advanced CMOS Setup

When you enter the Advanced CMOS Setup, this Setup
program is equipped with a series of help screens,
accessed through <F1> key, which will display the options
available for a particular configuration feature. All of the
items on the left side of the screen commonly seen so

16

they will not be explained in detail here. Here, we will only
focus on some special items that are found particularly in
ROCKY-328E board. These items are explained in detail
below :

 On-board IDE Controller :

The IDE hard disk drive can be Enable or Disable by
this item. When you do not need hard disk, the IDE
controller can be disabled.

 On-board Floppy Controller :

The floppy disk drive can be Enable or Disable by 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
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 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
set the I/O address of the parallel port or disable it.

 Parallel Port Mode :

ROCKY-318 provides EPP,ECP,ECP+EPP, and Normal
Mode.

 Primary Display :

You could set VGA/EGA, CGA40x25, CGA80x25,
Mono or Absent. When set Absent the ROCKY-328E

will not check the display adapter when power on the
system.

 System Keyboard :

You could set Present or Absent. When set Absent
the ROCKY-328E will not check the display adapter
when power on the system.

Appendix A. E2 Key™ Function

The ROCKY-328E provides an outstanding E2KEY™
function for system integrator. Based on the E

2

KEY™ you
could freely store ID Code, Pass Word, or Critical Data in
the 1Kbit EEPROM. Since the EEPROM is a type of
nonvolatile memory, you don’t have to worry losing very
important data.

Basically the E

2

KEY™ 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.

2

When you want to use the E

KEY™ function, you should
find the utility in the package. The software utility will
include the following four files,

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

The E2KEY.OBJ provides two library function for user to

2

integrate their application with E

KEY™ function. These
library (read_e2key and write_e2key) are written and
compiled in C format. Please read the following statement
and you will know to use it. It is pretty easy.

unsigned int read_e2key(unsigned int address)

2

/* This function will return the E

KEY™’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)

18

/* 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 accurate usage, please refer to EKEYDEMO.C
code beforehand.

2

Please note the E

KEY™ function is based on parallel port
operations so you should first enable ROCKY-328E’s
parallel port. Otherwise will be not working.

If you need Windows NT/95 driver for this function. Please
download relative drivers from

ftp.icpacquire.com.tw.

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.

The Watch-Dog Timer is controlled by two I/O ports.

443

(hex)

043

(hex)

To enable the Watch-Dog Timer, a reading action 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 JP10. 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 JP9.

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.

Read

Read Disable the Watch-Dog Timer.

Enable the refresh the Watch-Dog

Timer.

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

Watch-Dog Timer, otherwise the system will reset.
