-
- Introduction
- ------------
-
- NJRAMD is a device driver that allows you to partition a
- part of your EMS or EEMS memory as an extremely
- efficient, extremely fast "RAM disk" drive. Having a
- part of your memory configured as a RAM disk will allow
- you to store temporary files, intermediate files, and
- other information quickly.
-
- NJRAMD is compatible with the Lotus/Intel/Microsoft EMS
- standard, as well as the AST/Quadram/Ashton-Tate EEMS
- standard. NJRAMD will function equally well with both
- systems. NJRAMD was developed under LIM EMS 3.2, and
- has been tested on LIM EMS 4.0 systems successfully.
-
- This program will also run with any version of DOS,
- staring with version 2.00 or later. I wrote it under
- PC-DOS 3.1, and tested it under PC-DOS 2.00 and PC-DOS
- 2.10. The program should work with MS-DOS, but it
- hasn't been "officially" tested.
-
- NJRAMD takes up very little DOS space -- the program,
- depending on the configuration that you use, takes
- around 720 bytes of DOS memory, regardless of how large
- the disk space is made. The smallest configuration of
- NJRAMD takes under 700 bytes of DOS memory. Thus, you
- can partition a very large RAM disk, and only take up a
- very small portion of precious DOS memory.
-
-
- Use and Installation
- --------------------
-
- NJRAMD is installed as a DOS device driver when DOS is
- first loaded. Thus, you must specify the device driver
- in the CONFIG.SYS file of your boot disk or diskette.
- The entry in the CONFIG.SYS file must be anywhere
- *after* the specification for the EMS device driver.
- For example, the EMS driver that came with my Taiwanese
- EMS clone is called INITIAL.SYS. I also use ANSI.SYS,
- which I specify in the CONFIG.SYS file, also. Thus, my
- CONFIG.SYS file looks like this:
-
- device=\sys\initial.sys
- device=\sys\ansi.sys
- device=\sys\njramd.sys
-
- | Starting with version 1.20, this version, NJRAMD also
- | comes with a file specially prepared for computers with
- | extended instruction sets. This includes processors
- | like the 80186, 80286, and 80386. You can also make
- | use of this version if you have a NEC V-20 or V-30
- | installed and running in your system.
-
- | The version is called NJRAMDXP.SYS. "XP" stands for
- | "Enhanced Processor". This version of NJRAMD is coded
- | to take advantage of the special, extra instructions that
- | some CPU's have. It is slightly smaller, and
- | considerably faster than the standard version. If this
- | version doesn't work on your system, use the regular
- | version.
-
- | Even if you only have a stock PC with a NEC V-20, you
- | can expect the newver version of NJRAMD to be up to 5%
- | faster in benchmark tests. On a real 80286 system, the
- | program will run up to 9% faster.
-
- | See the paragraph just before "Technical Information" if
- | you have a PC's Limited computer.
-
- You might also have settings for the BUFFERS, FILES,
- STACKSPACE, and BREAK settings in your CONFIG.SYS file.
- These settings can remain unchanged, as they are
- independent of NJRAMD.
-
- You can find more information on the uses of the
- CONFIG.SYS file in the DOS manual. The section is
- called "Configuring your system".
-
- If you install NJRAMD as shown above, NJRAMD will
- default to a disk of 32 EMS Pages, which is 512
- kilobytes. (One EMS Page is equal to 16 kilobytes of
- storage space. 16 kilobytes stores 16384 bytes, or
- characters, of information.) If you would like to have
- a larger or smaller RAM disk, you must specify the /P
- option on the same line as NJRAMD in your CONFIG.SYS
- file. NJRAMD allocates space in one-page increments.
- Since each EMS page is 16k bytes long, you can adjust
- the size of NJRAMD in 16k increments.
-
- For example, to specify a RAM disk that is 100 pages
- long, use this line in your CONFIG.SYS file:
-
- device=njramd.sys /P100
-
- NJRAMD will try to take 100 pages of EMS memory -- this
- will give you 1600k of RAM disk space.
-
- Of course, you must have enough free EMS memory at the
- time that NJRAMD is loaded to accomodate the requested
- size. If there isn't enough memory, NJRAMD will
- terminate with an error, and not install itself at all.
- If you have selected a size that is too big to fit, you
- will see the message
-
- Device not installed.
- Requested size too big to fit.
-
- Remember that if you don't tell NJRAMD otherwise, it
- will try to create a 512k RAM Disk.
-
- | In version 1.20 of NJRAMD, you can use the /A switch to
- | use *all* of the available EMS memory, automatically,
- | instead of specifying a /P option. Note, though, that
- | the /A option will not leave any memory for other EMS
- | programs, such as disk cache programs or for 1-2-3.
-
- If there is no EMS memory available, at all, when NJRAMD
- tries to load, you will see this message:
-
- Device not installed.
- No free EMM Memory.
-
- If you see this message:
-
- Device not installed.
- The EMM is not installed.
-
- the EMM for your system was not present when NJRAMD
- loaded. NJRAMD depends on the EMM for access to the EMS
- memory. The specification for your EMM driver *must*
- appear before the specification for NJRAMD in your
- CONFIG.SYS file.
-
- Once you have entered the proper information in your
- CONFIG.SYS file, you must reboot your computer so that
- the information in the file will take effect. When
- NJRAMD installs, it will print a copyright message, and
- some status information reguarding the memory that it
- has taken, and the amount of memory that is available as
- a RAM disk.
-
- If you have any problems installing NJRAMD, please feel
- free to write to me. I'd be happy to help!
-
-
- Clicking
- --------
-
- I programmed NJRAMD to click the system's speaker every
- time the disk was accessed. Since a RAM disk is silent,
- it's often hard to tell when it is working. To
- compensate for the fact that there is no "whirring" or
- "chirping" going on while the RAM disk is active, the
- speaker clicks while the program accesses the memory.
-
- If you find this annoying, you can turn it off by
- specifying the "/S" option in the CONFIG.SYS entry. For
- example,
- device=njramd.sys /P16 /S
-
- would create a 16-page (256k byte) RAM disk that does
- not click when it is accessed. If you specify the /S
- option, NJRAMD will print the message
-
- Clicking Suppressed.
-
- when it is installed.
-
- | If you have an PC's Limited computer, with a Smart-Vu
- | display, try using the program NJRAMDPL.SYS. This
- | version is the same as the other versions, but it
- | writes to the Smart-Vu display. When NJRAMD is writing,
- | the display will show "NJ-W", and when it is reading, it
- | will show "NJ-R". Other than the statements that take
- | care of the display, this version of the program is
- | identical to NJRAMDXP.SYS.
-
- | If you have a PC's Limited and do not want NJRAMD to
- | access the Smart-Vu display, use the NJRAMDXP.SYS
- | program.
-
-
-
- Technical Information
- --------- -----------
-
- I have included the assembly language source code in
- this .ARC file (or on your white distribution disk) for
- your reference. You do not need it to run the program.
- If you are a programmer, or simply have an interest in
- "what makes it go", you can take a look at the
- NJRAMD.ASM file. I've heavily commented it, and
- therefore will not describe it in greater detail here.
-
-
- Shareware
- ---------
-
- This program is a work of Shareware. If you use the
- program, I expect you to end a registration fee of $15.
-
- Registering your copy of NJRAMD will automatically
- entitle you to free updates. I'd like to receive a
- dollar with each update request; this will let me just
- about break even, with the cost of diskettes, postage,
- and mailers.
-
- If you would like to write to me, my address is
-
- Mike Blaszczak
- 112 Verlinden Drive
- Monroeville, PA 15146-2041
-
- I'm also available on Participate On NWI as NIFTY JAMES.
- My BIX id is blaszczak, and I can be found on GEnie as
- M.BLASZCZAK.
-
- Please feel free to send your comments, questions,
- suggestions, donations, marriage proposals, and
- get-rich-quick schemes.
-
- I'm really interested in hearing any ideas that you
- have about NJRAMD, as well as any questions you have
- about it. If you run into any problems, please feel
- free to call or write. (I don't give my phone number,
- but, if you're serious enough, call directory
- assistance.)

-
- A Special Note
- --------------
-
- This program would not have been possible without the
- outstanding generosity and good will of Doctor File
- Finder and Bob Brody.
-
- Hats off to a couple of wonderful people!
-
- Doctor File Finder managed to find a bug in the first
- version that sometimes caused the program to trash the
- files on the disk -- the GetSector procedure wasn't
- working properly. The problem has been corrected in
- this version, and the program's optimization in the
- GetSector proceudre is now fully functional.
-
- Again, the Good Doctor helped me track down the bug that
- sometimes caused this device driver to ignore the /Page
- option. Thanks, Doc! The fix was made, and this is
- now Version 1.15.
-
- | Version 1.20 just let me flex my 80286 knowledge by
- | adding the additional instructions. The program also is
- | the first version to be developed under Microsoft Macro
- | Assembler Version 5.00.
-
- | Version 1.30 was released to refelect my newfound status
- | in the Association of Shareware Profesionals.
