2.2 Unpacking Precautions

Some components on ROCKY-5ST86HV SBC are very sensitive
to static electric charges and can be damaged by a sudden rush
of power. To protect it from unintended damage, be sure to
follow these precautions:

 Ground yourself to remove any static charge before touching

your ROCKY-5ST86HV SBC. You can do it by using a grounded
wrist strap at all times or by frequently touching any conducting
materials that is connected to the ground.

 Handle your ROCKY-5ST86HV SBC by its edges. Don’t touch IC

chips, leads or circuitry if not necessary.

 Do not plug any connector or jumper while the power is on.

AMI BIOS Setup

The ROCKY-5ST86HV uses the AMI PCI/ISA BIOS for system
configuration. 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 powering on the system, the BIOS will enter the Power­On-Self-Test (POST) routines. These routines will be executed
for system test, initialization and system configuration verification.
After the POST routines are completed, the following message
will appear:

" Hit DEL if you want to run SETUP"

To access AMI PCI/ISA BIOS Setup program, press <Del> key.
The following screen will be displayed at this time.

When choose
will load the minimized settings for Troubleshooting. The
performance should be very poor when use this setting.

4.2 Standard CMOS Setup

4.3 Advanced CMOS Setup

The Standard CMOS Setup is used for basic hardware system
configuration. The main function is for Date/Time setting and
Floppy/Hard Disk Drive setting. Please refer to the following
screen for this setup.

For IDE hard disk drive setup, please check the following setup
procedure:

1. Use the Auto setting for detection during boot up.

2. Use the IDE HDD AUTO DETECTION in the main menu to
automatically enter the drive specifications.

3. Manually enter the specifications by yourself from
the ”User“ option.

The Advanced CMOS Setup is designed for user's tuning best
performance of the ROCKY-5ST86HV board. As for normal
operation, users don‘t have to change any default setting. The
default setting is pre-set for most reliable operation.

Users can set “System Keyboard” to “Absent “ for the
applications which don't need keyboard.

You can change the value of each option by using <PgUp> and
<PgDn> key. The available values are shown on the right screen.

if you run the OS/2 operating system, this

option must be set to yes.

System BIOS Cacheable >



to define whether or not the
memory segment FOOOH can be read from or written to cache
memory. Setting it Enabled will give faster execution in your
system.

XXXX, 16k Shadow >



ROM Shadow is a technique in which
BIOS code is copied from slower ROM to faster RAM. If you
enable it then the BIOS will be executed from the RAM. Each
option allows 16KB segment to be shadowed to the RAM.

These setup functions mainly work for Chipset. These options are used
to change the Chipset‘s registers. Please carefully change any default
setting, otherwise the system may become unstable.

378 or 278. You can set the I/O address of the parallel port or
disable it.

When you enter the Peripheral Setup, the following items are
available for setting:

On-board FDC >

The floppy disk drive controller can be
Enabled or Disabled by this item. When you do not need floppy
disk, the FDD controller can be disabled. If you set it Auto, the
BIOS will try to enable any floppy drive controller on the ISA
Bus.

Serial Port A >



The options are Disable, 3F8, 2F8, 3E8, 2E8
and Auto. You can set the I/O address of the serial port A
(COMA) or disable it.

ROCKY-5ST86HV provides EPP Mode.
EPP passes the parallel port to be used with devices which
stick to the EPP specification. The existing parallel port signals
will be used by EPP to provide asymmetric bi-directional data
transfer driven by the host devices.

Parallel Port IRQ >

to define the Interrupt Request (IRQ) which

to set the DMA Channel used by

the parallel port.

Serial Port B >

Appendix A. Watch-Dog Timer

The Watch-Dog Timer is provided to ensure that stand-alone
systems can always recover from catastrophic conditions that
cause 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 perform hardware reset
(cold boot) to bring the system back to a known state.

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

To enable the Watch-Dog Timer, users have to define the Timer
before enable the Watch-dog Timer function. The output data is
a value of time interval and the range of the value is from 01(hex)
to FF(hex) and time interval 1 sec to 255 sec.

This will enable and activate the countdown timer which will
eventually time out and reset the CPU to ensure that this reset
condition does not occur, the Watch-Dog Timer must be
periodically refreshed by reading the same I/O ports 843H and
443H. This must be done within the time out period that is
selected by software, please refer to the example program.
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 the Watch-

Dog Timer, otherwise the system will reset.

TIMER_START = 443H
TIMER_STOP = 843H
