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.
You can successfully install the Microsoft MS-DOS versions 6.0 and later Upgrade over Digital Research(R) 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:
DISABLING SECURITY FEATURESIf 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 ProtectionTo disable password protection for a specific file, type the following at the command prompt:
password <filename> /nwhere <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> /nwhere <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 /ngWhen 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 ProtectionIf 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 UTILITYIf 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:
DISABLING THE GOTO AND ? COMMANDSIf 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 COMMANDIf 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 CompressedIf 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 CompressedIf your computer uses disk compression, and drive C is compressed, do the following:
Program and Does Not Have Enough Free Disk Space to Set Up MS-DOSIf 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.
