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.

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

2.4 System Memory DRAM
There are four 72-pin SIMM sockets to accept Paged/EDO
1MB,2MB,4MB,8MB,16MB,32MB,or 64MB memory modules.
The total capacity is from 2MB to 256MB.Customers have to
install at least 2pcs RAM module on board,SIMM Socket 1,2
or 3,4. From right side to left side,the SIMM sockets are SIMM
1,SIMM 2,SIMM 3,SIMM 4. There also have a 168-pin DIMM
socket for SDRAM. When install the 168-pin DIMM,then will not
allow to install 72-pin SIMM1 and SIMM2.

2.5 Watch-Dog Timer
The Watch-Dog Timer is enabled by reading port 443H. It should
be triggered before the time-out period ends, otherwise it will
assume the program operation is abnormal and will issue a reset
signal to start again, or activate NMI to CPU. The Watch-Dog
Timer is disable by reading port 043H.

2.6 DiskOnChip™Flash Disk
The DiskOnChip™Flash Disk Chip(DOC) is produced by M-
Systems. Because the DOC is 100% compatible to hard disk and
DOS.Customer don‘t need any extra software utility. It is just
“plug
and play”,easy and reliable. Right now the DOC is available from
2MB to 72MB.There also have PROMDISK-Chip™can be used
with the same socket. There have two sockets for the DOC. Based
on the two sockets,customer could have two Flash Disk Drives.
And in the future the DOC and PROMDISK-Chip will upgrade
firmware to allow two flash disk chips combined to one drive.
At that time the total capacity will be up to 144MB.
The DiskOnChip will share only 8KB memory address for each
one
