--------------------------------------------------------------------
The information in this article applies to:
 
 - Microsoft MS-DOS operating system versions 6.0, 6.2, 6.21, 6.22

How to Install MS-DOS 6.x over DR-DOS
 
This information applies to both Microsoft DoubleSpace and Microsoft
DriveSpace. For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands
and filenames.
 
SUMMARY
=======
 
You can successfully install the Microsoft MS-DOS versions 6.0 and later
Upgrade over Digital Research® DOS (DR DOS) version 5.0 or 6.0; however,
before you upgrade your current installation of DR DOS or Novell DR-DOS,
you should disable the following:
 
 - DR DOS security features
 - DR DOS DELWATCH utility
 - DR DOS GOTO and ? commands
 - DR DOS CHAIN command
 
NOTE: If you use the SuperStor® (STOR) data-compression program provided
with DR DOS, you should also read the section in this article titled "Your
Computer Uses DR DOS Disk Compression."
 
DISABLING SECURITY FEATURES
===========================
 
If you have any security features, including password protection, disable
them. When you run the Setup program for the MS-DOS 6.0 or later Upgrade,
your system, system files, DR DOS directory, and files in your DR DOS
directory cannot be password protected. The MS-DOS Upgrade Setup program
cannot create an Uninstall disk if your CONFIG.SYS or AUTOEXEC.BAT file
is password protected.
 
Disabling Password Protection
-----------------------------
 
To disable password protection for a specific file, type the following
at the command prompt:
 
   password <filename> /n
 
where <filename> is the file you want to remove the password from.
When you are prompted for the password, type it and then press the
ENTER key.
 
To disable password protection for a specific directory, type the
following at the command prompt
 
   password <dirname> /n
 
where <dirname> is the directory you want to remove the password from.
When you are prompted for the password, type it and then press the
ENTER key.
 
To disable password protection for the entire system, type the
following at the command prompt:
 
   password /ng
 
When you are prompted for the password, type it and then press the
ENTER key.
 
   WARNING: The MS-DOS 6.0 and later Upgrade Setup program cannot create
   an Uninstall disk if your CONFIG.SYS or AUTOEXEC.BAT file is
   password protected. If any of your DR-DOS system files or your
   DR-DOS directory are password protected, use the DR-DOS password
   command to disable the password protection before you install
   MS-DOS 6.0 or later.
 
Disabling Master Key Password Protection
----------------------------------------
 
If you installed the Master Key password security option with DR DOS,
you must run DR DOS Setup again to disable it. For more information on
this feature, see your DR DOS documentation.
 
DISABLING THE DELWATCH DELETE-PROTECTION UTILITY
================================================
 
If you have the DELWATCH delete-protection utility installed on your
computer, you must disable it and purge your deleted files before you
install MS-DOS 6.0 and later. To disable the DELWATCH utility:
 
1. Use an ASCII text editor to open your AUTOEXEC.BAT file.
 
2. Remove the command that loads DELWATCH, save the file, and then
   quit the text editor.
 
3. Remove any disks in your floppy disk drives, and then restart your
   computer by pressing CTRL+ALT+DEL.
 
4. Run the DELPURGE utility to purge your hard disk of pending delete
   files.
 
DISABLING THE GOTO AND ? COMMANDS
=================================
 
If your CONFIG.SYS or AUTOEXEC.BAT file uses any conditional DR DOS
commands (such as ? or GOTO), remove those commands and adjust the
order of the remaining commands accordingly. For more information on
the DR DOS GOTO and ? commands, see your DR DOS documentation.
 
DISABLING THE CHAIN COMMAND
===========================
 
If your CONFIG.SYS file contains the DR DOS CHAIN command, remove it
and adjust the other CONFIG.SYS commands accordingly. For more
information on this command, see your DR DOS documentation.
 
YOUR COMPUTER USES DR DOS DISK COMPRESSION
==========================================
 
Drive C is Not Compressed
-------------------------
 
If your computer uses disk compression but drive C is not compressed,
run Setup as described in the "Getting Started" chapter of the "User's
Guide" for version 6.0 and later. When Setup displays the message "Your
CONFIG.SYS file contains commands that are not valid MS-DOS commands,"
select the Modify Original Files option.
 
Drive C is Compressed
---------------------
 
If your computer uses disk compression, and drive C is compressed, do
the following:
 
1. Determine which drive is your original uncompressed drive. For more
   information, see your DR DOS documentation.
 
2. Make backup copies of the CONFIG.SYS and AUTOEXEC.BAT files on
   your compressed drive and the DCONFIG.SYS file on your uncompressed
   drive.
 
3. Combine the two configuration files. For example, if drive D is
   your uncompressed drive, type the following at the command prompt:
 
      copy d:\dconfig.sys + c:\config.sys d:\config.sys
 
4. Copy the combined CONFIG.SYS file to drive C. For example, if drive
   D is your uncompressed drive, type the following at the command
   prompt:
 
      copy d:\config.sys c:\config.sys
 
5. Copy your AUTOEXEC.BAT file to your uncompressed drive. For example, if
   drive D is your uncompressed drive, type the following at the command
   prompt:
 
      copy c:\autoexec.bat d:\autoexec.bat
 
6. Run Setup.
 
7. When Setup displays the message "Your CONFIG.SYS file contains
   commands that are not valid MS-DOS commands," select the Modify
   Original Files option.
 
   When Setup displays the message "Because you are currently using
   the DR DOS operating system," choose Continue.
 
8. After Setup is complete, MS-DOS displays an "Unrecognized command"
   message on your screen for each command in your AUTOEXEC.BAT and
   CONFIG.SYS files that is not a valid MS-DOS command. Remove these
   commands from your CONFIG.SYS and AUTOEXEC.BAT files.
 
9. Add the following command to the beginning of your CONFIG.SYS file,
   and then restart your computer:
 
      device=c:\dos\himem.sys
 
Setup Displays the Message "Your Computer Uses a Disk-Compression
Program and Does Not Have Enough Free Disk Space to Set Up MS-DOS
------------------------------------------------------------------
 
If Setup displays the message "Your computer uses a disk-compression
program and does not have enough free disk space to set up MS-DOS,"
you must convert your DR DOS 6 SuperStor compressed drive to an MS-DOS
6.0 or later DoubleSpace drive using the procedure below. This is
necessary because the DR DOS 6 SuperStor program does not provide the
functionality for increasing the size of your uncompressed host drive.
 
1. Using the DR DOS BACKUP command, back up your program and data
   files. For more information on using the BACKUP command, refer to
   your DR DOS documentation.
 
2. Insert the MS-DOS 6.0 or later Setup Disk 1 in drive A or B and use the
   SETUP command with the /F switch. For example, if you inserted Setup
   Disk 1 in drive A, type the following at the MS-DOS command prompt
   and then press ENTER:
 
      a:setup /f
 
   IMPORTANT: After you type the above command and Setup prompts you
   to insert a disk to create the startup floppy disk, you must
   create that disk in drive A. Also, be sure that you choose to
   install on drive A.
 
3. Make sure that the startup disk you created in step 2 is in drive
   A, and then restart your computer by pressing CTRL+ALT+DEL.
 
4. Use the MS-DOS FORMAT command to reformat all your drives. When you
   format drive C, be sure to use the /S parameter to make the disk
   bootable. To do this, type the following command at the MS-DOS
   command prompt and then press ENTER:
 
      format c: /s
 
5. Use the MS-DOS 6.0 or later RESTORE command, which is located on the
   startup disk you created in step 2, to restore your program and data
   files. For example, to restore your files from drive A to drive C,
   type the following command at the MS-DOS command prompt and then
   press ENTER:
 
      restore a: c:\*.* /s
 
   IMPORTANT: Do not restart your computer before proceeding to step 6.
 
   NOTE: If some of your files cannot be restored to your hard disk
   because you don't have enough disk space, you need to install the
   MS-DOS 6 or later Upgrade, run DoubleSpace to compress your hard disk,
   and then restore your files. After you finish restoring your files,
   continue with step 6.
 
6. To remove your DR DOS files, install the MS-DOS 6 or 6.2 Upgrade again.
   To do this, insert the MS-DOS 6 or laster Setup Disk 1 in drive A, type
   SETUP, and follow the instructions on your screen.
