              DYNAMIC   MEMORY   CONTROL
              ▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄


1.0   Introduction

Dynamic Memory Control enhances the memory management capabilities of any DOS
based PC, allowing dynamic loading and unloading of Device Drivers and TSR's
(Terminate and Stay Resident Programs) at your command.

Dynamic Memory Control is the answer for today's complex Networking software,
allowing you to change Device Drivers and TSR's, clearing them out of memory 100%
without ever having to Reboot your system or maintain multiple CONFIG.SYS or
AUTOEXEC.BAT files.

Dynamic Memory Control has been designed to work with both Conventional and or
High Memory found in your PC.  Note: In order to access High Memory, you require
a Memory Manager which can remap the are between 640K and 1 Mb. Nothing
extra is needed if you only use Conventional memory (the first 640K).


2.0   Features

*     Brings DOS new life

*     Easy to use with no complicated installation required.

*     Requires less than 10K to install.

*     Works with both Conventional and High Memory.

*     Uses as little as 1.4K of memory.

*     Eliminates the need for multiple CONFIG.SYS files.

*     No need to Reboot your system to accommodate different
      configurations of Device Drivers and TSR's programs.

*     Dynamic Loading of Device Drivers outside of CONFIG.SYS.

*     Eliminates the need for Device Drivers to be loaded in at system
      Bootup time.

*     Dynamically Unloads Device Drivers and TSR programs from
      Conventional or High Memory.

*     Device Drivers and TSR's can be loaded or unloaded on demand,
      interactively from DOS, within a batch file or from your favourite
      menu system.

*     Can be used to Dynamically Load Network Drivers.

*     Allows Dynamic loading and unloading of Multiple RAMDRIVEs using
      either Expanded or Extended Memory.

*     Password protection capability for limiting access.

3.0   Requirements:

*     DOS 2.0 - 4.x

*     640K RAM

*     High Memory Management Software for use with High Memory (such as
      QEMM from Quarterdeck).


4.0   General Information

This program works with both Conventional as well as High Memory.  To use
DMC in High Memory, you need a Memory Manager like QEMM from Quarterdeck.

When using High Memory, you must specify which Region Number you wish to load
your memory Resident program into.

Regions are contiguous areas of High Memory that have been converted by a Memory
Manager into High Ram so that you may load memory Resident Programs into them.

The first contiguous High Memory Region is known as Region 1, with the next
contiguous area Region 2, then Region 3, Region 4 and so on.

The number of Regions your system will have is directly related to the number and
type of adapter cards (such as Monochrome, Vga, Network cards etc..) you have and
the location of System Rom and Bios within your system.


5.0   The Commands    (NOTE, FREENOTE, LDEVICE)

5.10  The NOTE Command

By entering the command NOTE, prior to loading a single or group of memory
Resident Programs, Dynamic Memory Control places a Marker in your systems memory
similar to a book marker found in a book.

NOTES should be loaded into memory prior to loading any memory Resident Programs.

They can be loaded into High or Conventional Memory.

An example of a NOTE command using Conventional Memory and it's associated screen
output is as follows:

      NOTE

      NOTE installed successfully

The combined maximum number of NOTES allowed in High and Conventional Memory at
any one time is 24.

When NOTES are placed in High Memory you must specify which Region Number you
require the NOTE in.

An example of a NOTE command using High Memory, loading into High Memory Region
Number 2 and it's associated screen output is as follows:

      LOADHI /R:2 NOTE

      NOTE installed successfully

5.11  Using a single NOTE to load Multiple Memory Resident Programs

NOTES are not required to be placed with every memory Resident routine you load,
but only at the start of certain groups that you wish to segregate and
distinguish between.


5.12  Using Password Protected NOTES  (NOTE -p ########)

In addition to specifying a NOTE command by itself, there is also an optional
parameter -p that provides the ability to specify an optional password along with
each NOTE you wish to password protect.

The Command Langauge for using password protected NOTES is as follows:

      NOTE -p ########

      Where:

      "-p"        Indicates you wish to use a password protected NOTE.

      "########"  Indicates the password you wish to use. The password used may
          range from 1 to 8 characters, and is case insensitive (upper
          and lower case are treated the same).

Password protecting NOTES can provide System security to prevent users from
accidental removal of sacred memory resident system configurations from memory.

Such as: Network Drivers, RAMDRIVEs, a Mouse Driver, ANSI.SYS, a Disk Cache etc..


5.20  The FREENOTE Command

By entering the command FREENOTE, Dynamic Memory Control restores your systems'
memory back to its' status prior to issuing the matching corresponding NOTE
command.

The maximum number of FREENOTES possible is 24.

Entering a single FREENOTE command by itself will only remove a single NOTE and
it's associated memory Resident Programs.

All memory Resident Programs loaded after a NOTE will be unloaded from memory
every time a matching corresponding FREENOTE command is entered.

The command is as follows:    FREENOTE

This tells Dynamic Memory Control to only remove the last NOTE

When NOTES have been placed in specific High Memory Regions, all memory Resident
Programs that were loaded in that Region after the last NOTE command are unloaded
from memory, every time a matching corresponding FREENOTE command is issued.

5.21  Using FREENOTE to Remove Password Protected NOTES

If you wish to remove a NOTE that has been entered with password protection,
(NOTE -p ########) you must use FREENOTE along with the same optional -p
parameter and password that was used with the associated NOTE command.

The Command Langauge for using FREENOTE to remove password protected NOTES is as
follows:

      FREENOTE -p ########

Where:

      "-p"        Indicates you wish to remove a password protected NOTE.

      "########"  Indicates the 1 to 8 character password that was used with the
          NOTE command.


5.22  Using FREENOTE to Remove Multiple NOTES

Dynamic Memory Control also makes it possible to remove any number of NOTES
within a single command.  It works as follows:

      FREENOTE -a

Where "-a" tells Dynamic Memory Control to remove all NOTES and their
corresponding memory resident programs.

      FREENOTE -nn

Where "nn" represents the number of NOTES you wish to remove.  For example if you
had 8 NOTES loaded and you wanted to remove the last 3 NOTES, you could enter the
following command:

      FREENOTE -3

When you use FREENOTE to unload memory resident routines, it unloads them in the
reverse order to how they were loaded in.  It removes the most recent programs
first and so on until your system's memory status was restored to the state it
was before the NOTE and it's associated memory Resident Programs were loaded.


5.23  Using FREENOTE with Expanded Memory

Dynamic Memory Control has been designed to work with programs capable of
utilizing either Extended and or Expanded Memory.

There are no differences in the commands used to Dynamically load either type of
memory, however if you wish to Dynamically unload an Expanded Memory program you
must specify so by adding an -x parameter to the appropriate FREENOTE command.


5.24  Using FREENOTE with Programs that access Extended Memory

Dynamic Memory Control treats Extended memory in a manner similar to Conventional
Memory.  If you use FREENOTE to remove a program or group of programs from
memory, all Conventional and Extended Memory allocated by them after the
corresponding NOTE will be released.

5.30  Using FREENOTE with a Token Ring Network

Dynamic Memory Control also has a special provision for releasing the memory
associated with a Token Ring Network.

The Token Ring Network is one situation where the command FREENOTE by itself will
not totally clear the memory.

FREENOTE -t is entered to remove the areas of memory used by the Token Ring and
allow reinstallation of the Token Ring.


5.40  The LDEVICE Command

Dynamic Memory Control uses the command LDEVICE to enable Dynamic loading of
Device Drivers when you want them, such as in a batch file or in your favourite
menu system.

With LDEVICE there is absolutely no need to load Device Drivers into CONFIG.SYS.

LDEVICE works with both Conventional and or High Memory.

LDEVICE works in conjunction with the commands NOTE and FREENOTE.

If you wish to be able to Dynamically unload a particular Device Driver you must
issue a NOTE command prior to using LDEVICE.

The corresponding FREENOTE command should be used when you are ready to
Dynamically unload the Device Driver or Drivers that were loaded using the
LDEVICE command.

The basic command language statement for using LDEVICE is as follows:

LDEVICE d:\path\filename optional-parameters

Where:        The command "LDEVICE" indicates that you wish to Dynamically load a
        Device Driver.

        "d:" represents the Disk Drive letter where the Device Driver
        resides.

        "path" represents the Subdirectory if applicable where the Device
        Driver is stored.

        "filename" the name of the Device Driver that you wish to
        Dynamically load.

        "optional-parameters" such as the /1 or /2 that you may sometimes
        use with software such as a Mouse Driver to tell it which COM port
        you are using.


5.41  Using LDEVICE to Dynamically load RAMDRIVEs

Using LDEVICE, you have the ability to Dynamically load Expanded and Extended
Memory RAMDRIVEs at will.  When used in conjunction with the appropriate NOTE and
FREENOTE commands, you can dynamically unload RAMDRIVEs at will.

This demo is a complete version of the software, without the REMOVE
utility which can remove Memory Managers. It is also limited to a single
NOTE in memory. The full version allows 24 NOTEs.  The ordering information
which appears at the start of each utility is not part of the full version.
