1 Introduction

Thank you for choosing ROCKY-318 386SX Single Board Computer. ROCKY-318 is
an ISA with PC/104 form factor board, equipped with ALI 6117 (including 386SX
CPU) and advanced high-performance multi-mode I/O, designed for system
manufacturers, integrators, or VARs that want to provide reliable and quality
performance at a reasonable price.

An advanced high performance super AT I/O chip SMC FDC37C665 or equivalent
chip is used in the ROCKY-318 board. Both on-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 FDC37C665
incorporates sophisticated power control circuitry (PCC). The PCC supports
multiple low power down modes.

The most outstanding feature in the ROCKY-318 is built-in PC/104 expansion bus.
Based on the PC/104 bus, you can easily install over thousands of PC/104
modules from hundreds of vendors in the world. ROCKY-318 has external power
connector that can connect to power supply directly. It is more suitable for your
standalone applications.

In addition, ROCKY-318 provides one 72-pin SIMM (Single In-line Memory Module)
socket to install a maximum of 32MB memory (single side RAM). The board is
also designed with 1MB DRAM on board for OEM customer.

4 AMI BIOS Setup

ROCKY-318 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 Started

When the system is powered on, BIOS will enter Power-On-Self-Test routines.
These routines will be executed for System Test and Initialization and System
Configuration Verification. After POST routines are completed, the following
message will appear:

" 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 t he following features:

i. Date/Time

ii. Hard Disk Type

iii. Floppy Disk Type

All of these features are almost the same as common, so we do not describe
more detailed in here.

20

4.3 Advanced CMOS Setup

When you enter 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.

There are a few special items which are specified as below:

•

On-board IDE Controller: 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 Floppy Controller: The floppy disk drive can be Enabled or Disabled
by this item. When you do not need floppy disk, 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: 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-318 will not check the display adapter
when power on the system.

•

System Keyboard: You could set Present or Absent. When set Absent the
ROCKY-318 will not check the display adapter when power on the system.

Appendix A E2 Key™ Function

2

ROCKY-318 provides an outstanding E

2

Based on the E

KEY™ you could free to store 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 can 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

KEY™ function for system integrator.

EKEYDEMO.C
EKEYDEMO.EXE

The E2KEY.OBJ provides two-library function for user to integrate their application

2

with E

KEY™ function. These libraries (read_e2key and write_e2key) are
written and compiled in C format. Please check the following statement, and then
you will know how to implement it easily.

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)

2

/* This function will write the given data to E

KEY™ 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.

2

Note: E

KEY™ function is based on the working of parallel port. So you should

enable the parallel port of ROCKY-318, otherwise it will be not working.

22

Appendix B 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 properly, 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 Watch-Dog

Timer.

043 (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 JP1. To ensure
this reset condition does not occur, 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 JP8.

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 Watchdog Timer,
otherwise the system will reset.
