One characteristic of digital circuit is its fast response to high or low
signal. This kind of response is highly needed for harsh and critical
industrial operating environment. That’s why we design 4-bit digital
inputs and 4-bit digital outputs on the ROCKY-512.
Digital Input and Output, generally, are control signals. You can use
these signals to control external devices that needs On/Off circuit or
TTL devices. The register address is 240H, 260H or 280H that can
be selected in BIOS SETUP Menu. You can read or write data to the
selected address to enable the function of digital IO.

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

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

2. Use the IDE HDD AUTO DETECTION in the main menu; the
computer will automatically detect the HDD specifications.

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

Note: If you need more information on any particular field, just

highlight it then press <F1> button. A pop-up window will
come out to give you more information on that field.

27

4.3 BIOS Features Setup

This BIOS Features Setup is designed for the 'fine tuning' of your
system in order to improve its performance. As for normal operation,
you don‘t have to change any default setting. The default setting is
pre-set for most reliable operation.

4.11 IDE HDD AUTODETECTION

This option detects the parameters of an IDE hard disk drive (HDD
sector, cylinder, head, etc) automatically and will put the parameters
into the Standard CMOS Setup screen. Up to 2 IDE drives can be
detected and the parameters will be listed in the box. Press <Y> if
you accept these parameters. Press <N> to skip the next IDE
drives.

Note: If your IDE HDD was formatted in previous older system,

incorrect parameters may be detected. In this case, you need
to enter the correct parameters manually or low-level format
the disk

Chapter 5. SVGA Setup

5.1 Introduction

The ROCKY-512 is equipped with on-board VGA interface. The
description below is its specifications and features:

5.1.1 Chipset

The ROCKY-512 uses a Cyrix CX5530A chipset as its SVGA
controller for traditional analog CRT monitors. The VGA BIOS
does not support LCD. Moreover, it also accepts interlaced and
non-interlaced analog monitors (color and monochrome VGA)
with high-resolution quality while maintaining complete IBM VGA
compatibility. How ever, digital monit ors (i.e. M DA, CGA, and E GA)
may NOT be supported. Multiple frequency (multisync) monitors
will be operated as if they were analog monitors.

5.1.2 Display memory

Having 1.5 ~ 4 MB UMA memory, the VGA controller can make
CRT displays or color panel displays perform with resolutions up
to 1024 x 768 at 64 K colors. The display memory can be
modified up to 4 MB in BIOS for true-color resolution of 1024 x

768.

38

5.1.3 Display drivers

1. Win95, 98 drivers (VGA) in \VGA\MediaGX\National Geode
Win9x Drivers 1.2

2. WinNT4.0, Windows 2000 driver in

\VGA\MediaGX\Nt40Vga\

5.2 Further Information

For more detailed information about the PCI/SVGA installation in
your ROCKY-512, including driver updates, troubleshooting
instructions, please refer to the following webs, which provide some
resources you may need. If not find the information you need,
please contact with your local contributor or ICP support team:

Chapter 6. PCI Bus Ethernet Interface

The ROCKY-512 provides a high performance 32-bit Ethernet
chipset, which is completely compliant with IEEE 802.3 100 Mbps
CSMA/CD standards. As it is both 100Base-T and 10Base-T
compatible so it is suitable for most major network operating
systems.

The Ethernet port supplies a standard RJ-45 connector on board. To
utilize the network boot feature is by incorporating the boot ROM
image files for the appropriate network operating system.

Appendix A. Watchdog Timer

The Watchdog Timer is a device to ensure that standalone 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 normally, hardware on
the board will perform hardware reset (cold boot) to bring the
system back to a known state.

Three I/O ports control the Watchdog Timer.

443 Write Set Watchdog Time period
443 (hex) Read Enable the refresh the Watch-Dog Timer.
043/843 (hex) Read Disable the Watchdog Timer.

Prior to enable the Watchdog Timer, the user has to define Timer
first. 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.

DATA TIME INTERVAL

01 1 sec
02 2 sec
03 3 sec
04 4 sec

.
.
.

FF 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 Watchdog Timer must be periodically
refreshed by reading the same I/O port 043/843H 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 5% 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

.
.
.

41

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

Watchdog Timer, otherwise the syst em will reset.

Example Assembly Program

TIMER_PORT = 443H
TIMER_START = 443H
TIMER_STOP = 843H
