0.7 STATIC ELECTRICITY PRECAUTIONS

Before removing the board from its anti-static bag, read this section about static electricity precautions.
Static electricity is a constant danger to computer systems. The charge that can build up in your body may be
more than sufficient to damage integrated circuits on any PC board. It is, therefore, important to observe basic
precautions whenever you use or handle computer components. Although areas with humid climates are much
less prone to static build-up, it is always best to safeguard against accidents may result in expensive repairs. The
following measures should generally be sufficient to protect your equipment from static discharge:

• Touch a grounded metal object to discharge the static electricity in your body (or ideally, wear a grounded
wrist strap).

• When unpacking and handling the board or other system component, place all materials on an antic static
surface.

• Be careful not to touch the components on the board, especially the “golden finger” connectors on the bottom
of every board.

Features

1.1 INTRODUCTION

This card is a byte wide memory card that plugs into any free slot of your system. Five 32-pin JEDEC DIP sockets
may be populated with up to 5MB of EPROM, 2.5MB of FLASH/SRAM or combinations of these chips. Especially
AR-B1047, it supports up to 72MB DiskOnChip.
The AR-B1047 supports 12V and 5V FLASHs. This enables you to program FLASHs on board directly. If small
page (less or equal to 512 bytes per page) 5V FLASHs are used, you can format the FLASH disk and copy files
onto the FLASH disk just like a normal disk. If you want to use the 12V FLASH, please use the external 12V
voltage, the AR-B1047 does not support the 12V voltage. This feature will extend the life of your FLASH chips by
only reprogramming a small area. You could use all of the related DOS command (such as COPY, DEL, … etc.) to
update files on the 5V FLASH disk.
An on-board Lithium battery ensures the data retention of SRAM or an external battery packed that may be
connected to the AR-B1047. A write protect function allows you to prevent data on SRAM disk or FLASH disk from
accidental deletion or overwrite.
The AR-B1047 solid-state disk card is extremely easy to install and use. However, it is advised that you read this
manual before you begin installation.
The AR-B1047 is a solid-state disk card that can be used as the system disk or as a replacement for mechanical
disk drives in any IBM PC/XT/AT or compatible computer. It is ideal for, but not limited to, the following
applications:

Diskless PC workstations

!

High reliability and/or high speed access applications

!

Heavy duty disk access requirements

!

PC controller for industrial or line test instruments.

!

Environments hostile to standard floppy disks & drives. (Dust, moisture, vibration, etc.)

2.2 SYSTEM SETTING

Jumper pins allow you to set specific system parameters. Set them by changing the pin location of jumper blocks.
(A j u mp er bl oc k i s a sm al l pl as ti c- en ca se d c on du c to r [ sh or ti ng pl ug ] t h at s li p s o ve r t he pi ns . ) To change a jumper
setting, remove the jumper from its current location with your fingers or small needle-nosed pliers. Place the
jumper over the two pins designated for the desired setting. Press the jumper evenly onto the pins. Be careful not
to bend the pins.

We will show the locations of the AR-B1047 jumper pins, and the factory-default setting.

CAUTION: 1. Do not touch any electronic component unless you are safely grounded. Wear a grounded wrist

strap or touch an exposed metal part of the system unit chassis. The static discharges from your
fingers can permanently damage electronic components.

2. If you want to use the 12V FLASH, please use the external 12V voltage, the AR-B1047 does not
support the 12V voltage.

2.2.1 Battery Setting

(1) Battery Charge Select (JP1)

If the AR-B1047 uses a 3.6V Ni-Cd rechargeable battery for SRAM data retention, the on-board charged circuit can

2.4 MEMORY TYPE SETTING (M1, M2 & M3)

Before installing the memory into memory sockets MEM1 through MEM5, you have to configure the memory type,
which will be used (ROM/RAM) on the AR-B1047. You can configure the AR-B1047 as an EPROM (FLASH) disk
(ROM only), a SRAM disk (SRAM only) or a combination of EPROM (FLASH) and SRAM disk.
It is not necessary to insert memory chips into all of the sockets. The number of SRAM chips required depends on
your RAM disk capacity. The number of EPROM chips required depends on the total size of files that you plan to
copy onto the ROM disk and whether or not it will be bootable.
Insert the first memory chip into MEM1 if you are going to configure it as a ROM or SRAM disk. If you use a
combination of ROM and RAM, then insert the EPROM (FLASH) chip first from MEM1 and insert the SRAM from
the first socket is set as SRAM.
The M1 jumper block is used to configure the memory type of MEM1 and MEM2, M2 is for MEM3 and MEM4, M3

3.1 OVERVIEW

This chapter provides information for you to set up a working system based on the AR-B1047 card. Please read
the details of the card’s hardware descriptions before installation carefully, especially jumper settings and cable
connections.

Follow steps listed below for proper installation:

Step 1 :

Step 2 :

Step 3 :

Step 4 :

Step 5 :

Step 6 :

Make sure the base I/O address does not conflict with other I/O cards.

Make sure the memory address does not conflict with other memory cards.

Make sure the jumper settings for the memory are all installed properly.

Don’t use the shadow RAM on the firmware address.

If you have installed an EMS driver, don’t use the same range of memory address as the AR-B1047.

If you are using the MS-DOS 6.2 to format SRAM or small page 5V FLASH disk, you might get some bad
sectors in your FLASH/RAM disk. This will reduce the capacity of your FLASH/RAM disk. To solve this
problem, please type:

C:\>FORMAT [FLASH/SRAM disk letter] /S/U/C
or
C:\>FORMAT [FLASH/SRAM disk letter] /U/C

3.2 ROM DISK INSTALLATION

To support the AR-B1047 solid state disk’s operations, the following files has been provided some functions as
follows:

(A) PGM1047.EXE

PGM1047.EXE PGM1047.EXE is used to program the 12V FLASH EPROM after the ROM pattern files are

generated by RFG.EXE. The PGM1047.EXE can also program the correctness of the ROM
pattern files onto 5V FLASH EPROM (start from MEM1) or SRAM for testing the ROM pattern files.

3-1

AR-B1047 User’s Guide

To execute PGM1047.EXE, the main menu will be displayed on your screen. There are 8 options on the main
menu.

Quit to DOS
Quits and exits to the DOS.

OS Shell
Exits from PGM1047 temporarily to the DOS prompt. Type EXIT to return to PGM1047 main menu.

Load ROM File
If this option is used, the PGM1047 will prompt you for the ROM pattern file name. This option is useful if you
have not previously entered a ROM pattern file name or if you wish to use a different ROM pattern file. The
PGM1047 will check and display the ROM file name, ROM file size, (FLASH) memory capacity and the number
of ROM pattern files that will be loaded and copied onto the (FLASH) memory chips.

Verify Memory
If ROM pattern files were loaded without error, this option instructs PGM1047 to verify the contents of (FLASH)
memory chips with the current ROM pattern files.

Program Memory
If there are no mistakes in your ROM pattern file, then this menu option will erase (FLASH) memory, write the
current ROM pattern files onto (FLASH) memory and verify data that was just written to (FLASH) memory, using
the ROM pattern files.

Memory Type/Mfr.
Before you program the (FLASH) memory chips, make sure that the FLASH’s type and manufactory match the
one shown on the main menu. Otherwise, you can use this option to select the proper type and manufacture
and instruct the program to use a right programming algorithm.

Select PGM Chips
Normally the PGM1047 will program all ROM pattern files onto the FLASH memories with the ROM pattern files
just loaded. But you can use this option to select which memory chips that you want to program and which
memory chips need to be skipped. The PGM1047 will only program the selected chips when writing data to the
FLASH memory. This is very useful when some of the memory chip were verified and programmed previously.

Select FLASH PLSCNTs

If the 12V FLASHs have been programmed several times, please select the <Slowest> FLASH PLSCNT mode
instead of <Standard> mode. In the <Slower> or <Slowest> mode, PGM1047.EXE will retry more times to
program data onto the 12V FLASHs correctly.
The default setting is <Slowest> mode.

(B) WP1047.EXE

WP1047.EXE This program demonstrates how to enable and disable software writes protect function. It also

shows the current protect mode of write or read only memory.

3-2

AR-B1047 User’s Guide

(C) RFG.EXE

RFG.EXE This program is used to generate ROM pattern files in a binary format. Each ROM pattern file has

the same size as the FLASH or EPROM and can be easily programmed on to the FLASH with on­board programmer or on to EPROM with any EPROM programmer. If you have specified a DOS
drive in the *.PGF file, RFG will generate bootable ROM pattern files for the EPROM or FLASH
disk. The RFG supports the following DOS: MS-DOS, PC-DOS, DR-DOS, and X-DOS.

NOTE: If you want to use AR-B1047 with any DOS, which is not supported by RFG, please send your requirement

to Acrosser Technology Co., Ltd. or contract with your local sales representative.

The RFG.EXE provided in the utility diskette is a program that converts the files you list in the PGF and convert
them into ROM pattern file. The RFG will determine how many EPROMs are needed and generate the same
number of ROM pattern files. These ROM pattern files are named with the name assigned by the ROM_NAME in
the PGF and the extension names are *.R01, *.R02…etc. To generate ROM pattern files.
The ROM File Generator main menu will be displayed on the screen. There are 7 options on the main menu. They
serve the following functions:

Quit to DOS
Quits and exits to the DOS

OS Shell
Exits from the RFG temporarily to the DOS prompt. Type <EXIT> to return to the RFG main menu.

Load PFG File
If this option is used, the RFG will prompt you for the PGF file name. This option is useful if you have not
previously entered a PGF name or you wish to use a different PGF file. The RFG will check and display the
PGF filename, ROM pattern file name, EPROM’s capacity, DOS version and the number of ROM pattern files
that will be generated.

Type Current PGF File
This option instructs the RFG to use the DOS type command to display the contents of the current PGF file.

Generate ROM File(s)
If there is no mistake in your *.PGF file, then this menu option will generate ROM pattern files. The number of
ROM pattern file generated by the RFG will depend on the total capacity needed by your files. For instance, if 3
files are generated, then you will need to use 3 EPROMs (The size depends upon the number stated in your
PGF). The ROM pattern files will have the same file names, but will have different extension names. For
example:

TEST.R01, TEST.R02, TEST.R03 tc.

Display Error in PGF File
This option displays errors that were detected in your PGF.

Help to PGF File
This option gives information on how to write a PGF file and how to generate ROM pattern files. An example
PGF is also included.
Move the reverse video bar to <Generate ROM File(s)> then press [ENTER]. The ROM pattern file is a binary
file. The file size will be the same size as the EPROM that you assigned in the PGF. For example, if you are
using 128KX8 EPROM memory chips, then the size of ROM patterns file will be 131072 bytes. For other chips
the file size will be:

64KX8 EPROM----65536 bytes
256KX8 EPROM—262144 bytes

512KX8 EPROM---524288 bytes
1MX8 EPROM -----1048576 bytes

(D) RFGDEMO.PGF

RFGDEMO.PGF This file provides a sample PROGRAM GROUP FILE which illustrates how to create ROM pattern

files correctly.

The PGF is an ASCII text file that can be created by using any text editor, word processor or DOS <COPY CON>
command. The PGF lists what files will be copied and if DOS is going to be copied. This file can have any DOS
filename, but the extension name must be *.PGF. For example, followings are valid filenames.

RFGDEMO.PGF
MYRFG.PGF

3.3 USING THE WRITE PROTECT FUNCTION

The AR-B1047 provides software write protect functions for small page 5V FLASH disk and only software write
protect function for SRAM disk to prevent your data on 5V FLASH or SRAM disk from accidental deletion or
overwrite. If your FLASH/SRAM disk is write protected, any write operation to the protected FLASH/SRAM disk will
get a write protect error

Write protect error writing drive A
Abort, Retry, Fail?

If you need the write protect function and sometimes you have to write or update data on your FLASH/SRAM disk,
you can use the software write protect instead of hardware write protect. The software write protect function is
enabled or disabled by writing data to an I/O port.

(1) Enable the Software Write Protect

Writes 80H to the base port+0 address

Example 1: (in assembly language)
MOV DX,224H ; If the AR-1047’s base I/O address is 224H
MOV AL,80H ; Enable byte=80H
OUT DX,AL

Example 2: (in BASICA language)
OUT &H224,&H80 : REM If the AR-B1047’s base I/O address is 224H

Example 3: (in Turbo C language)
outportb(0x224,0x80) ; /*If the AR-B1047’s base I/O address is 224H*/

(2) Disable the Software Write Protect

Writes 0H to the base port+0 address

Example 1: (in assembly language)
MOV DX,224H ; If the AR-1047’s base I/O address is 224H
MOV AL,00H ; Disable byte=00H
OUT DX,AL

Example 2: (in BASICA language)
OUT &H224,&H00 : REM If the AR-B1047’s base I/O address is 224H

Example 3: (in Turbo C language)

the power is off. Please use low power SRAM chips for a longer data retention period. (These SRAM chips are
usually designated with a “L” in the chip model code.)

CAUTION: If you want to use the 12V FLASH, please use the external 12V voltage, the AR-B1047 does not

support the 12V voltage.

4. HOW TO USE THE MEMORY BANKS

This section provides the information about how to access the memory on the AR-B1047 without using the AR­B1047 SSD BIOS. The AR-B1047 hardware cut every 8K bytes of memory into a memory bank. To access the
data in memory, you have to assign the chip number and the bank number. On every chip, the memory bank
number starts from the number zero. The last memory bank number depends on the size of the memory chip used
on the AR-B1047. For example, if you use the 256K bytes memory chip, the bank number on every chip would be
in the range of 0 to 31. The chip number and the bank number are determined by the bank selected register and
the chip selected register on the AR-B1047.
The I/O address of these registers is determined by SW1-1 of SW1. The memory address of the memory bank is
located on the range selected by SW1-2 and SW1-7 of the SW1. Please refer to the how to select the I/O port
address and the memory address of the memory bank.
The I/O port address of the bank select register is base port+0 and the I/O port address of the chip select register
is base port + 2. The following is the format of the bank select register and chip select register.

For different types of memory, A0 to A6 have different explanations. These bits are used to select the bank
number of specific memory located by CS0 to CS2.

NOTE: BS0 to BS6 are the memory bank select bits. For example, 128KB memory has sixteen 8K-byte banks, so 4bits
