Creating a DOS 5.0 Image file for OS/2, 2.0

 After  lots  of  trial and error, reading all  the  on-line  help
 files, and two OS/2 books, I have finally gotten a DOS 5.0  image
 file to work properly.  To help others that have become frustrat-
 ed  with this process, I will try to put it all together for  you
 in this text file.

 -----------------------------------------------------------------

 1.  Create a bootable 360K or 720K diskette with DOS 5.0. You can
     use  high density diskettes if you wish, but each image  file
     you  create will equal the size of the diskette you  use.  By
     using a 360K diskette, your image files will only be 368K  in
     size.


 2.  Copy all of the following files to the bootable diskette:

     From:                      Filename:

          \OS2\MDOS                       ANSI.SYS
          \OS2\MDOS                       FSFILTER.SYS
          \OS2\MDOS                       EMM386.SYS
          \OS2\MDOS                       HIMEM.SYS
          \OS2\MDOS                       MOUSE.COM


 3.  Create a  CONFIG.SYS file on the Bootable diskette like the
     following:

     device=himem.sys
     device=emm386.sys
     dos=high,umb
     devicehigh=fsfilter.sys
     devicehigh=ansi.sys
     files=40
     buffers=30


 4.  Create a AUTOEXEC.BAT file on the bootable diskette like  the
     following:

     echo off
     set comspec=c:\dos\command.com
     lh mouse
     path c:\;c:\dos
     prompt $p$g
     c:
     cd \dos
     dos5-img.bat

     The last line of the AUTOEXEC.BAT file will load a batch file
     named  DOS5-IMG.BAT in the \DOS subdirectory. Use this  batch
             file  to continue executaion of other programs or  utilities.
     See step 5 for a sample batch file.


 5.  Create a batch file in the \DOS subdirectory named  DOS5-IMG.
     BAT similiar to the following:

       echo off
       \os2\mdos\fsaccess a:

     The second line of this batch file will release access to the
     image  file. Otherwise the DOS session thinks the image  file
     is  drive  A, and you will not have access  to  the  physical
     drive a on your system.


 6.  Open a  OS/2 window, and change to your DOS subdirectory,
     type:
          cd \DOS                <enter>
          VMDISK A: DOS5.IMG     <enter>

     This  will  create an image of the diskette  you  created  in
     steps 1 through 5. The image file will be named DOS5.IMG and
     will be located in the \DOS subdirectory.


 7. Exit the OS/2 Window, and return to the Desktop.


 8. Create a DOS Window object:

    a.  Open the " OS/2 System " folder.

    b.  Double click on the "Command Prompts" icon.

    c.  Copy the DOS Window icon to the Desktop by holding down
        the CTRL key and dragging the icon to the Desktop.

    d.  Close the "Command Prompts" and the "OS/2 System" folder.


 9.  Change the DOS Settings for the DOS Window icon:

    a. Select the "DOS Window" icon by clicking on it once.

    b. Bring up its menu by clicking the right mouse button once.

    c. Click on the ARROW on the "OPEN" line.

    d. Select "Settings".

    e. In the "DOS Window - Settings" notebook, select "Session".

    f. Select "DOS Settings".

    g. Change the following settings:

       1. DOS_HIGH           to:   ON
       2. DOS_SHELL          to:   C:\DOS\COMMAND.COM  C:\DOS\ /p
       3. DOS_STARTUP_DRIVE  to:   C:\DOS\DOS5.IMG

       Note:
       If your pc has a LAN adapter, or other board that uses RAM
       memory, add the range it uses to the MEM_EXCLUDE_REGIONS
       settings (ie, C800-CC00 for my Ethernet adapter).


       There may be other settings you wish to change, but don't
       do it yet. Get the DOS Window up and working first, then
       you can make other necessary changes.


 10.  Save the settings you changed, and exit the notebook.


 11.  Time to test all this stuff out. Double click on your new
      DOS 5 Window, and you there you are!


If  you have problems with the above steps, please  double  check
all  your  file and directory names, especially the ones  in  the
"DOS Settings".

If  anyone has additional information, corrections, or a  just  a
better  way  of  doing  this, please contact me  at  one  of  the
numbers below. The last thing I want to do is give out wrong,  or
insufficient  information. We will leave that up to the  software
companies (grin).
