Introduction

Welcome to the ROCKY-538TXV Pentium™ with VGA Single
Board Computer. The ROCKY-538TXV board is an ISA/PCI
form factor board, which comes equipped with high performance
Pentium 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.

This board built-in DiskOnChip™(DOC) Flash Disk for embedded
application. The DOC Flash Disk is 100% compatible to hard
disk. User can use any DOS command without any extra
software utility. The DOC currently is available from 2MB to
72MB. There also have PROMDISK-Chip™ can be used in the
same DOC socket as an alternative solution.

An advanced high performance super AT I/O chip – Winbond
W83977TF is used in the ROCKY-538TXV 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.

In addition, the ROCKY-538TXV provides four 72-pin SIMM
sockets and one 168-pin DIMM socket for its on-board DRAM.
The RAM module accepts 1MB, 2MB, 4MB, 8MB, 16MB, 32MB,
And 64MB. So,the total on-board memory can be configured
from 2MB to 256MB.

ROCKY-538TXV uses the advanced INTEL Chipset,430TX
which is 100% ISA/PCI compatible chipset.with PCI 2.1
standard.

• DMA channels : 7

• Interrupt levels : 15

• Chipset : Intel 430TX

• PCI VGA : with 2MB RAM
Resolution : 1280x1024,256 color,75Hz
1024x768, 64K color,75Hz
800x600,full color,90Hz

• Real-time clock/calendar : in 430TX chipset,backup by industrial

Li-battery,3V/850mAH. .

• RAM memory : 2MB to 256MB,SDRAM,EDO and standard DRAM

supported

• Second Cache memory : 512KB Pipelined Burst SRAM on board

• Ultra DMA/33 IDE Interface : up to four PCI Enhance IDE hard

drives. The Ultra DMA/33 IDE can handle data transfer up to
33MB/s. The best of all is that is new technology is compatible with
existing ATA-2 IDE specifications. So there is no need to do any
change for customer’ s current accessory.

• Floppy disk drive interface : two 2.88 MB, 1.44MB, 1.2MB, 720KB,

or 360KB floppy disk drives.

• Two high speed Series ports : NS16C550 compatible UARTs

• Bi-directional Parallel Port

5

• IrDA port : Support Serial Infrared(SIR) and Amplitude Shift

Keyed IR(ASKIR) interface.

• USB port : Support two USB ports for future expansion.

• Watch-dog timer : can be set by 1,2,10,20,110 or 220 seconds

period. Reset or NMI was generated when CPU did not periodically
trigger the timer. Your program use hex 043 and 443 to control the
watch-dog and generate a system reset.

• Flash Disk - DiskOnChip™:or PROMDISK-Chip™ : The Flash Disk

provide 100% compatible with hard disk. The built-in TrueFFS
Transparent Flash Block Management and Space Reclamation will
let customer to use the Flash Disk with DOS command, no need any
extra software utility.

• Keyboard connector

• Mouse : PS/2 Mouse Port on-board.

• Power Consumption : +5V @ 4.6A

( Pentium/MMX-200,16MB EDO RAM)

+12V @ 70mA , -12V@20mA

• Operating Temperature : 0° ~ 55° C ( CPU needs Cooler)

Installation

This chapter describes how to install the ROCKY-538TXV. At
first, the layout of ROCKY-538TXV is shown, and the unpacking
information that you should be careful is described. The
jumpers and switches setting for the ROCKY-538TXV's
configuration, such as CPU type selection, system clock setting,
and watch dog timer, are also included.

2.2 Unpacking

8

Your ROCKY-538TXV Single Board Computer contains
sensitive electronic components that can be easily damaged by
static electricity.

In this section, we describe the precautions you should take
while unpacking, as well as during installation. It is very
important that the instructions be followed correctly, to avoid
static damage, and to successfully install the board.

The system board should be done on a grounded anti-static mat.
The operator should be wearing an anti-static wristband,
grounded at the same point as the anti-static mat.

Inspect the cardboard carton for obvious damage. Shipping and
handling may cause damage to your board. Be sure there are no
shipping and handing damages on the board before processing.

After opening the cardboard carton, exact the system board and
place it only on a grounded anti-static surface component side
up.

Again inspect the board for damage. Press down on all the
socketed IC's to make sure that they are properly seated.
Do this only with the board place on a firm flat surface.

Note : DO NOT APPLY POWER TO THE BOARD IF IT HAS

BEEN DAMAGED.

You are now ready to install your ROCKY-538TXV Single Board
Computer.

•

CPU Core Voltage Selection :

Please check the CPU Core Voltage before you install the
CPU. Right now new Intel MMX CPU is dual voltages for
core and I/O,the I/O is 3.3V but the core is 2.8V. This kind
of CPU design will enhance the low power consumption
capability. As for the general Pentium CPU is one voltage for
I/O and Core - 3.3V,3.4V,or 3.5V
