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.

Introduction  
Packing List  
Features  
1.1 INTRODUCTION  
The AR-B7041 is a solid state disk card that can be used as the system disk or as a replacement for mechanical  
disk drives is any IBM PC/XT/AT or compatible computer. It is ideal for, but not limited to, the following  
applications:  
l
l
l
l
l
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.)  
This card is a byte wide memory card that plugs into any free slot of system. Eight 32-pin JEDEC DIP sockets  
may be populated with up to 8MB of EPROM, 4MB of FLASH EPROM/SRAM or combinations of them. The AR-  
B7041 also provides one piggyback connector to install AR-B7017 cards (4MB ROM/RAM/FLASH module), for  
maximum of 12MB disk space.  
Data retention of SRAM is ensured by an on-board Lithium battery or using an external battery pack that may be  
connected to the AR-B7041. A write protect function allows you to prevent data on SRAM disk or FLASH disk  
from accidental deletion or overwrite.  
The AR-B7041 and AR-B7017 supports 5V FLASH EPROMs. This enables you to program FLASH EPROMs on-  
board directly. If small page (less or equal to 512 bytes per page) 5V FLASHs are used, you can format FLASH  
disk and copy files onto the FLASH disk just like using a normal disk. This feature will extend the life of your  
FLASH EPROM chips by only reprogram a small area. You should use all of the related DOS command (such as  
COPY, DEL, etc.) to update files on the 5V FLASH disk.  
The AR-B7041 ROM/RAM disk card is extremely easy to install and use. However, it is advised that you read this  
manual before you begin to install.

2.1 OVERVIEW  
This chapter provides information for you to set up a working system based on the AR-B7041 card. Please read  
the details of the card s hardware descriptions before installation carefully, especially jumpers’ setting, switch  
settings and cable connections.  
When you install the card please notice the following item:  
1. Make sure the base I/O address does not conflict with other I/O cards.  
2. Make sure the memory address not conflict with other memory cards.  
3. Make sure the jumper settings for the memory are all installed properly.  
4. Don’ t use the invalid shadow RAM address.  
5. Prevent to use the same range of memory address as the AR-B7041 used, if you have install EMS driver.  
6. If you are using the MS-DOS 6.2 to format SRAM or 5V FLASH EPROM disk, you might get some bad  
sectors in your ROM/RAM disk. This will reduce the capacity of your FLASH/SRAM disk. To solve this  
problem, please type:  
C:\>FORMAT [drive number] /U/C  
or  
C:\>FORMAT [drive number] /U/C/S  
2.2 UTILITY DISKETTE – SSD UTILITY  
To support the AR-B7041 solid state disk s operations, the following files have been provided on the enclosed  
diskette.  
(A) PGM7041.EXE  
PGM7041.EXE PGM7041.EXE is used to program the 12V FLASH EPROM after the ROM pattern files are  
generated by RFG.EXE The PGM7041.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.  
To execute PGM7041.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 PGM7041 temporarily to the DOS prompt. Type EXIT to return to PGM7041 main menu.  
Load ROM File  
If this option is used, the PGM7041 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 PGM7041 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.  
2-1  
 
AR-B7041 User¡¦s Guide  
Verify Memory  
If ROM pattern files were loaded without error, this option instructs PGM7041 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 PGM7041 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 PGM7041 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, PGM7041.EXE will retry more  
times to program data onto the 12V FLASHs correctly. The default setting is <Slowest> mode.  
Move the reverse video bar to the “ Program Memory” option then press ENTER. PGM7041 will write the ROM  
pattern files onto the (FLASH) memories. Ensure that data is verified by the PGM7041 correctly.  
(B) SWAP41.EXE  
SWAP41.EXE  
This program demonstrates how to reassigns your AR-B7041 card to the drive unit set by  
SW1-5, SW1-6 and SW1-7. This file should be executed in the first line of your  
<AUTOEXEC.BAT> file.  
(C) AUTOEXEC.BAT  
AUTOEXEC.BAT This is a sample batch file to illustrate how to create an <AUTOEXECT.BAT> file, if you are  
planning to use the AR-B7041 as a boot drive.  
(D) 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 on-board 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-B7041 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:  
2-2  
 
AR-B7041 User¡¦s Guide  
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 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 etc.  
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  
(E) 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  
MSDOS.PGF  
….  
2-3  
 
AR-B7041 User¡¦s Guide  
An examples of the *.PGF file is as follow.  
ROM_NAME=TEST1  
DOS_DRIVE=C:  
; ROM pattern file name is TEST1  
; The output file names will be TEST1.R01, TEST1.R02..etc.  
; DOS system drive unit is drive C:  
; If user does not want to copy DOS system files onto the ROM disk  
; write as DOS_DRIVE=NONE  
ROM_SIZE=128  
; 128 means 128KX8 (27C/29F010) EPROM size used  
; 256 means 512KX8 (27C/29F020) EPROM size used  
; 512 means 512KX8 (27C/29F040) EPROM size used  
; 1024 means 1MX8 (27C080) EPROM size used  
The following 3 files are options which depend on whether the ROM disk is to be bootable or not.

(F) WD7041.EXE  
WD7041.EXE  
This program demonstrates how to enable and trigger the watchdog timer. It allows you to  
test the <TIMES-OUT & RESET> function when the watchdog timer is enabled.  
(G) WP7041.EXE  
WP7041.EXE  
This program demonstrates how to enable and disable software write protected function. It  
also shows the current protect mode of write or read only memory.  
2.3 WRITE PROTECT FUNCTION  
The AR-B7041 provides hardware and software write protect functions for small page 5V FLASH disk and only  
software write protected function for SRAM disk. This is 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  
About, Retry, Fail?  
2.3.1 Hardware Write Protect  
To enable the hardware protect function for small page 5V FLASH disk set the SW1-8 and SW1-9 to the ON and  
OFF position, please refer to the “ Switch Setting” .  
2.3.2 Software Write Protect  
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 a data to an I/O port.

2.4 WATCHDOG TIMER  
This section describes how to use the Watchdog Timer, disabled, enabled, and trigger.  
The AR-B7041 is equipped with a programmable time-out period watchdog timer. User can use the program to  
enable the watchdog timer. Once you have enabled the watchdog timer, the program should trigger it every time  
before it times out. If your program fails to trigger or disable this timer before it times out because of system hang-  
up, it will generate a reset signal to reset the system. The time-out period can be programmed to be 3 to 42  
seconds.

2.4.1 Watchdog Timer Setting  
The watchdog timer is a circuit that may be used from your program software to detect crashes or hang-ups.  
Whenever the watchdog timer is enabled, the LED will blink to indicate that the timer is counting. The watchdog  
timer is automatically disabled after reset.  
Once you have enabled the watchdog timer, your program must trigger the watchdog timer every time before it  
times-out. After you trigger the watchdog timer, it will be set to zero and start to count again. If your program fails  
to trigger the watchdog timer before time-out, it will generate a reset pulse to reset the system.  
The factor of the watchdog timer time-out constant is approximately 6 seconds. The period for the watchdog timer  
time-out period is between 1 to 7 timer factors.  
If you want to reset your system when watchdog times out, the following table listed the relation of timer factors  
between time-out period.

To enable the watchdog timer, you have to output a byte of timer factor to the watchdog register whose address is  
base port+3m 76h or 77h. The following is a BASICA program which demonstrates how to enable the watchdog  
timer and set the time-out period at 24 seconds.

2.4.4 Watchdog Timer Trigger  
After you enable the watchdog timer, your program must write the same factor as enabling to the watchdog register  
at least once every time-out period to its previous setting. You can change the time-out period by writing another  
timer factor to the watchdog register at any time, and you must trigger the watchdog before the new time-out period  
in next trigger. Below is a BASICA program which demonstrates how to trigger the watchdog timer:

If you are going to install the EMM386.EXE driver, please use the [X] option to prevent EMM386.EXE from using  
the particular range of segment address as an EMS page which is used by AR-B7041. For example, write a  
statement in the CONFIG.SYS file as follow: (If the memory configuration of AR-B7041 is CC00:0)  
DEVICE=C:\DOS\EMM386.EXE X=CC00-CFFF  
3.2.4 SSD Drive Number (SW1-5, SW1-6 & SW1-7)  
The AR-B7041 can simulate one or two disk drives. You can assign the drive number of AR-B7041 by configure  
SW1-5, SW1-6 & SW1-7.  
If you have copied DOS to the ROM/RAM disk, the computer will always boot from the ROM/RAM disk. After the  
DOS is booted, the first disk number will be A: until the program SWAP41.EXE is executed. The SWAP41.EXE  
changes the drive number according to the setting of SW1-5, SW1-6 & SW1-7.  
If your AR-B7041 does not have DOS and is not assigned as drive A, the computer will boot from your hard disk or  
floppy disk. In this case, the BIOS of AR-B7041 will set the drive number of ROM/RAM disk to desired drive  
number automatically without having to run SWAP41.EXE after system booting. Do not assign the AR-B7041 with  
drive 0 (drive A: ) when the ROM/RAM disk does not have DOS. This is just like that you put a non-DOS disk in  
the floppy disk.  
If you install only one kind of memory chip on the ROM/RAM disk, the AR-B7041 will simulate one disk drive.

3.3 JUMPER SETTING  
Jumper pins allow you to set specific system parameters. Set them by changing the pin location of jumper blocks.  
(A jumper block is a small plastic-encased conductor [shorting plug] that slips over the pins.) 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-B7041 jumper pins, and the factory-default setting.  
CAUTION: 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.  
3.3.1 Memory Type Setting (M1 ~ M4 & JP1)  
Before installing the memory into memory sockets MEM1 through MEM8 you have to configure the memory type  
which will be used (ROM/RAM) on the AR-B7041 card. Each jumper selects the memory type of four continuous  
sockets.  
You can configure the AR-B7041 as a (FLASH) EPROM disk (ROM only), a SRAM disk (SRAM only) or a  
combination of (FLASH) EPROM 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 (FLASH) EPROM chip starting with the MEM1, and insert the  
SRAM chips starting from the first socket which is configured as SRAM.  
l
l
l
l
M1: is used to configure the memory type of MEM1 to MEM2  
M2: is used to configure the memory type of MEM3 to MEM4  
M3: is used to configure the memory type of MEM5 to MEM6  
M4: is used to configure the memory type of MEM7 to MEM8  
CAUTION: When the power is turned off, please note the following precautions.  
1. If your data has been stored in the SRAM disk, do not change the jumper position or data will be  
lost.  
2. Make sure jumpers are set properly. If you mistakenly set the jumpers for SRAM and you have  
EPROM or FLASH installed, the EPROM or FLASH will drain the battery’ s power.

AR-B7041 User¡¦s Guide  
CAUTION: It is not recommended that the user formatted the disk and copy files to the FLASH disk very often.  
Since the FLASH EPROM s write cycle life time is about 10,000 or 100,000 times, writing data to the  
FLASH too often will reduce the life time of the FLASH EPROM chips, especially the FLASH EPROM  
chip in the MEM1 socket.

5. MEMORY BANKS & INDEX  
5.1 USING MEMORY BANKS  
This chapter provides the information about how to access the memory on the AR-B7041 without using the AR-  
B7041 SSD BIOS. The AR-B7041 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-7041. 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-B7041.  
The I/O addresses of these registers are determined by of SW1-1 and SW1-2. The memory address of the  
memory bank is located on the range selected by SW1-3 and SW1-4.  
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 +1. The following is the format of the bank select register and bank enable register.

AR-B7041 User¡¦s Guide  
CAUTION: BS0 to BS6 are the memory bank select bits. For example, 128KB memory has sixteen 8K-byte  
banks, so 4 bits (BS0 to BS3) are needed.  
Example 1:  
Example 2:  
Select the 10th bank of the MEM4 on the AR-B7041. The AR-B7041 is using 27C020 (256K*8),  
and the base port is &H220.  
100 base_port=&H220  
110 OUT base_port+0,&H19  
120 OUT base_port=1,&H13  
Select the last bank of MEM5 on the second AR-B7017 piggyback module. The AR-B7017 is using  
27C040 (512K*8), and the base port is &H3A0.  
200 base_port=&H3A0  
210 OUT base_port+0,&H3F  
220 OUT base_port+1,&H1C  
5.2 EXPANDING THE AR-B7041’ S MEMORY CAPACITY  
There are 2 ways to expand the AR-B7041’ s memory capacity. One is installing 2 AR-B7041 cards in one system  
and other is using the AR-B7017 memory expansion module.  
Up to two AR-B7041 cards can be installed simultaneously. The AR-B7041 firmware will automatically link all of  
the AR-B7041 cards. In order to use multiple cards, be sure that the AR-B7041 firmware address and base I/O  
ports meet the following requirements:  
l
l
All of the AR-B7041 cards must have contiguous I/O base port  
Each AR-B7041 firmware address must be set to occupy a contiguous area of memory.  
The following table illustrates all of valid settings:

AR-B7041 User¡¦s Guide  
The AR-B7041 provides 8 sockets for memory chips. Each AR-B7041 card also could be piggy-backed 1 AR-  
B7017 to have more sockets for more memory capacity. Five combinations of AR-B7041 and AR-B7017 are valid,  
they are as following:

The AR-B7017 accepts the same kinds of memory chips that the AR-B7041 uses. Every AR-B7017 provides eight  
32-pin JEDEC DIP sockets for a maximum of 4MB FLASHs, EPROMs or SRAMs. The AR-B7017 is installed on  
the AR-B7041 through the piggyback connector CN1. When you create the ROM pattern files with extensions  
exceeding .R08, the files with extensions .R01 to R08 are placed in the first AR-B7041 card from MEM1 to MEM8,  
and the files with extensions .R09 to .R16 go into the AR-B7017 installed on the first AR-B7041 or the second card  
from MEM1 to MEM8 if no AR-B7017 module, etc.  
If no AR-B7017 is used, the locations and sequence of memory chips are listed on the following table:
