the CPU (if necessary), DRAM installation, jumper settings for CPU, cache
and standard I/O.
Pre-Configuration
Handling Precautions
The Hunter Industrial has been designed to be as rugged as possible but
it can be damaged if dropped, jarred sharply or struck. Damage may also
occur by using excessive force in performing certain installation procedures
such as forcing the system board into the chassis or placing too much
torque on a mounting screw.
Take special care when installing or removing the system memory SIMMs.
Never force a SIMM into a socket. Screwdrivers slipping off a screw and
scraping the board can break a trace or component leads, rendering the
board unusable. Always handle the Hunter Industrial with care.
Special Warranty Note:
Products returned for warranty repair will be inspected for damaged caused by improper installation and misuse as described in the previous section and the static warning below. Should the board
show signs of abuse, the warranty will become void
and the customer will be billed for all repairs and
shipping and handling costs.
Static Warning
The Hunter Industrial contains delicate electronic semiconductors that are
highly sensitive to static electricity. These components, if subjected to a
static electricity discharge, can be weakened thereby reducing the serviceable life of the system board. BEFORE THE BOARD IS REMOVED FROM
ITS PROTECTIVE ANTISTATIC PACKAGING TAKE PROPER PRECAUTIONS! Work on a conductive surface that is connected to ground.
Before touching any electronic device, ground yourself by touching an
unpainted metal object or, and highly recommended, use a grounding strap.

Chapter 1: Pre-Configuration
Your Hunter Industrial is equipped with a large number of peripherals and
has the ability to run at a variety of speeds without the need to change any
crystals or oscillators. As such, there is a large number of configuration
jumpers on the board. Taken step by step, setting these jumpers is easy.
We suggest you review each section and follow the instructions.
Jumper Types
Jumpers are small copper pins attached to the system board. Covering two
pins with a shunt closes the connection between them. The Hunter
Industrial examines these jumpers to determine specific configuration
information. There are three different categories of jumpers on the Hunter
Industrial.
A.Two pin jumpers are used for binary selections such as enable,
disable. Instructions for this type of jumper are open, for no shunt
over the pins or closed, when the shunt covers the pins.
B .Three or four pin jumpers are used for multiple selection. Instruc-
tions for these jumpers will indicate which two pins to cover. For
example: for JPx 2-3 the shunt will be covering pins 2 and 3 leaving
pins 1 and 4 exposed.
C .Grouped Jumpers are used when a certain function has multiple
selections. There are two grouped jumpers on the board and
careful attention should be given when setting these jumpers.
Instructions for grouped jumpers are similar to those above Jumper Location and Pin Numbers.

I/O Port IRQ Selection
The parallel port and both serial ports must have their IRQs. Normally,
these settings can be left in their default settings and only when conflicts
arise should they be changed. Jumper JP20 is used to select the parallel
port IRQ. Jumper JP19 is used to select the first serial port's IRQ. Jumper
JP18 is used to select the second serial port's IRQ. Use Table 1-8 to select
the IRQs for these options.

Chapter 1: Pre-Configuration
Step 2 - DRAM, CPU and Cables
Installation
Depending upon how your Hunter Industrial is configured you may need
to install the following:
•DRAM (SIMMs)
•CPU
Hunter Triton Configuration
The Hunter Industrial uses standard or EDO 70ns access speed
or faster SIMMs. It is very important that the quality of the
SIMMs is good. Undesirable operation of the system may result
if poor quality SIMMs are used. Always purchase your memory
from a reliable source.
The Hunter Industrial uses standard 32 or 36-Bit
SIMMs. They are slight larger than other 9-Bit
SIMMs that are also commonly used on systems
boards. They are configured into four, 8-Bit (or 1
Byte) sections. Thus, a total of 32 Bits ( no parity)
or 36 Bits (with parity) are stored. This is often
confusing because these SIMMs are commonly
referred to as 256K by 32 or 36 or 1MB by 32 or 36.
To determine the actual capacity of the SIMM,
simply multiply the 256K, 512K or 1MB by 4. Thus
the actual SIMMS capacity is 1MB, 2MB and 4MB
respectively.
Installing Memory Modules
The Hunter Industrial has 4 memory module sockets. The order in wich
they should be populated is from the inside of the board outward. Note that
each socket is labeled: SM1, SM2, SM3, SM4. Refer to figure 1.3.
At least TWO memory modules MUST be installed
at a time.
9
Hunter Industrial - Installation Guide
When inserting the memory modules, note the notch on the edge of each
module. This notch is designed to permit insertion in only one way. This
notch must be pointed towards the keyboard connector.
Start with the innermost socket (SM1). Gently place the module into the
desired socket at a 30-45° angle. Then gently rotate or rock the module
into an upright position. Never force a memory module into itssocket. Rather, double check the notch and gently rock it into place.
When the module has been properly installed, the metal latches on either
side of the memory module will “click” into place. (See figure 1-2).
Repeat the mentioned steps until all memory modules are installed. No
jumpers are involved in DRAM configuration.
Figure 1-2 SIMM Insertion
10
Gently place the SIMM into the desired socket
at 30°- 45° angle.
Then gently rotate or rock the SIMM into an
upright position. Never force a SIMM into
its socket.
Double check the notch and gently rock it into
place if properly installed the SIMM will "click".

CPU Installation
The Hunter Industrial currently supports the following CPUs:
1. Improper installation of the CPU may cause
permanent damage to both the system board and
the CPU. -- Void of warranty
2. Always handle the CPU by the edges, never
touch the pins.
3. Always use a heatsink and CPU fan.
11
Hunter Industrial - Installation Guide
Using Figure 1-4, locate the diagonal notch on the CPU chip. This notch
represents pin one. The Pentium processor also has small dot as well
indicating pin 1. DO NOT USE THE CHIP LOGO OR LETTERINGTO LOCATE PIN ONE.
Locate the CPU socket on your Hunter Industrial system board. Pin 1 on
the socket is located in the lower left hand corner of the socket.
Figure 1-4 CPU Alignment
To install the Pentium processor lift the lever of the ZIF socket and gently
insert the CPU. Make sure the CPU is inserted all the way. Lower the
lever. See figure 1-5.
Figure 1-5 CPU Socket alignment
Pin # 1Lever

Chapter 1: Pre-Configuration
This completes the installation of the CPU. Now is a good time to double
check both the CPU and SIMM installation to make sure that these devices
have been properly installed.

Connect the power supply cables to the system board. There is no formal
convention for color coding the wires on power supplies except for ground
wires which are black. Use figure above to determine the proper cable
locations.
Next install the control panel cables for each of the control panel headers.
These headers are located along the bottom of the board. Again, there is
no standard convention for color coding these cables. However, the
connectors for “Key lock/Power LED” and “Speaker” are keyed. While
the actual connector on the cable harness may not be keyed, there will
probably be a wire missing.

Hunter Industrial - Installation Guide
Installing Peripheral Cables
Begin with the top of the Hunter Industrial system working left to right.
Refer Figure 1-1 for the locations of each of the peripheral connectors.
Now it is a good time to install the internal peripherals such as floppy and
hard disk drives. Do not connect the power cable to these peripherals as it
is easier to attach the bulky ribbon cables before the smaller power
connectors. If you are installing more than one IDE drive double check your
master/slave jumpers on the drives. Review the information supplied with
your drive for more information on this subject.
Connect the floppy cable (not included) to the system board. Then connect
remaining ends of the ribbon cable to the appropriate peripherals.
Finally, connect the IDE cable (not included) to the system. Then connect
remaining ends of the ribbon cable to the appropriate peripherals. This
concludes the hardware installation of your Hunter Industrial system.
Now it is a good time to re-check all of the cable connections to make
sure they are correct. It is also a good idea to label each of the external
peripheral connectors - COM1, COM2, Mouse and Parallel.

Two Levels of Passwords
Both the Supervisor and the User icons configure password
support. If you use both, the Supervisor password must be set
first. The system can be configured so that all users must enter a
password every time the system boots or when WINBIOS Setup
is executed, using either or both the Supervisor password or User
password.
34
Chapter 2: Bios Configuration
If You Do Not Want to Use a Password
Just press <Enter> when the password prompt appears.
Setting a Password
The password check option is enabled in Advanced Setup by
choosing either Always (the password prompt appears every time
the system is powered on) or Setup (the password prompt appears
only when WINBIOS is run). The password is stored in CMOS
RAM. The following screen appears when you select the password icon from the WINBIOS Setup main menu.
You can enter a password by:
Typing the password on the keyboard or
Selecting each letter via the mouse.
When you select Supervisor or User, the BIOS prompts for a
password. You must set the Supervisor password before you can
set the User password. Enter a 1 – 6 character password. The
password does not appear on the screen when typed. Make sure
you write it down. If you forget it, you must drain CMOS RAM and
reconfigure the system.
Changing a Password
Select the appropriate password icon (Supervisor or User) from
the Security section of the WINBIOS Setup main menu. Enter the
password and press <Enter>. The screen does not display the
characters entered. After the new password is entered, retype the
new password as prompted and press <Enter>.
If the password confirmation is incorrect, an error message appears. If the new password is entered without error, press <Esc>

If your board has the optional FLASH BIOS installed, you will be able to
update your BIOS without having to replace the EPROM. The WinBios will
read the new BIOS file from a floppy disk, replace the old BIOS and reboot
your computer.
When updating your BIOS, make sure you have a disk with the correct BIOS
file (it’s size should be 128K).
Rename the file to “AMIBOOT.ROM”. Turn your computer off. Insert the
disk in Drive A:, turn the computer on while pressing <CTRL><HOME>.
Your computer will show no screen, but will beep to indicate what is being
done.
If the programming is successful, you should hear the 4 beeps and your

Appendix C Troubleshooting
Power-On Self Test
The BIOS featured in the Hunter Industrial provides all IBM
standard Power-On Self Test (POST) routines as well as enhanced
BIOS POST routines. The BIOS POST supports CPU internal
diagnostics. The BIOS POST checkpoint codes are accessible via
the manufacturing Test Port (I/O port 80h).
Post Phases:
Every time the system is powered on. The BIOS executes two
types of POST routines:
System Test and Initialization (test and initialize BIOS for
normal operations).
System Configuration Verification (compare defined configuration with hardware actually installed).
BIOS Error Reporting:
If the error occurs before the display device is initialized a series
of beeps sound. Beep codes indicate that a fatal error has occurred.
The BIOS beep codes are described on the next page.
If the error occurs after the display device is initialized the error
message is displayed. A prompt to press <F1> can also appear
power is on.
Fatal errors, which halt the boot process, are communicated
through a series of audible beeps.
