FastTips: MS-DOS 6.2 Upgrade Questions and Answers

Last reviewed: July 29, 1996
Article ID: Q105078

The information in this article applies to:

  • Microsoft MS-DOS operating system versions 6.2, 6.22
1. Q. When I run the Setup program for the MS-DOS 6.2 Upgrade, my
      video display is unreadable; either the instruction lines are
      truncated or the screen text is unreadable. How can I correct
      this problem?

   A. If you are running MS-DOS Setup and your monitor is not
      displaying the setup screens properly, use the following steps:

      1. If you have not already done so, quit Setup by pressing the
         F3 key twice.

      2. Insert Setup Disk 1 in drive A or drive B. At the MS-DOS
         command prompt, type "a:\setup /i" or "b:\setup /i" (without
         the quotation marks) and then press ENTER.

      The /I switch disables automatic hardware detection. Since
      display problems can be caused by incorrect hardware settings,
      make sure you enter the correct display type when Setup prompts
      you for it.

      If the setup screens still display incorrectly, you may need to
      manually install MS-DOS 6.2. For instructions on how to do this,
      refer to your printed MS-DOS 6.2 documentation.

2. Q. Setup repeatedly prompts me to insert the same disk or indicates
      that my Uninstall disk is not the correct disk. How should I
      troubleshoot this problem?

   A. Your computer may contain memory-resident or disk-caching
      programs that prevent Setup from correctly reading the floppy
      disk. Remove or remark out any memory-resident programs that are
      started from the AUTOEXEC.BAT or CONFIG.SYS files, restart the
      computer, and then run Setup again. If the problem persists, you
      may be able to successfully install MS-DOS by using the
      following steps:

      1. Create a temporary directory on your hard disk.

      2. Use the COPY command to copy all files from the MS-DOS 6.2
         Upgrade disks to the temporary directory.

      3. Run the Setup program for the MS-DOS 6.2 Upgrade from the
         temporary directory.

3. Q. I'm using Stacker, and when I try to install the MS-DOS 6.2 Upgrade,
      I receive an error message and cannot continue. How can I correct
      this problem?

   A. If you recently acquired Stacker 3.1, you may need to run a STAC
      Electronics patch before upgrading to MS-DOS 6.2.

      If your Stacker 3.1 files show a date and time stamp of 06-03-93
      3:10a, you can install MS-DOS 6.2. If the file dates and times are
      later than these, you need to run the 62STAC.EXE patch before
      installing MS-DOS 6.2. This file can obtained from the Utilities
      section of the STAC forum on CompuServe or by calling STAC
      Electronics Technical Support.

      MS-DOS 6.2 was tested with the original Stacker version 3.1. Because
      version 3.1 was changed without notice, you must use the patch
      with the revised version before running MS-DOS 6.2 Setup.

      The patch temporarily updates the Stacker driver in memory;
      you must run MS-DOS 6.2 Setup immediately after running
      62STACK.EXE. If you have already installed MS-DOS 6.2 Upgrade or
      Step-Up, uninstall using your Uninstall disk, run the patch, and then
      reinstall MS-DOS 6.2.

4. Q. I want to install MS-DOS 6.2 Upgrade; however, I'm using Stacker
      version 3.11 and when I try to install MS-DOS 6.2 Upgrade, I receive
      an error message and cannot continue. How can I correct this problem?

   A. At the time MS-DOS 6.2 was released, the current version of Stacker
      was 3.1. Microsoft ensured that MS-DOS 6.2 Upgrade and MS-DOS 6.2
      Step-Up can detect Stacker 3.1 and do not overwrite it. This ensures
      that you can access your Stacker-compressed drives.

      Since Microsoft cannot guarantee how MS-DOS will interact with future
      versions of Stacker, MS-DOS 6.2 Setup is not designed to detect and
      install correctly with versions of Stacker later than 3.1.

      To work around this problem, contact STAC Electronics to obtain the
      62STAC.EXE file, or follow the procedure below. You can order the
      62STAC.EXE file from STAC Electronics, or you can download it from
      the STAC Electronics bulletin board service at (619) 431-7405.

      For more detailed information, order FastTips Technical Library item
      Q107526, titled "Installing MS-DOS 6.2 over Stacker Version 3.11."

5. Q. Can I install the MS-DOS 6.2 Upgrade on my IBM PS/1 computer?

   A. You can upgrade to MS-DOS 6.2 if you have an IBM PS/1; however,
      if your IBM PS/1 is configured to boot from read-only memory
      (ROM), you must first change your system configuration so that
      it can boot from your hard disk (usually drive C). To do this,
      use the procedure in your printed MS-DOS 6.2 documentation.

6. Q. I am using the Stacker disk-compression program. When I run MS-
      DOS 6.2 Setup, I receive the message "Your computer uses a disk-
      compression program and does not have enough free disk space to
      set up MS-DOS." How should I troubleshoot this problem?

   A. This error occurs if Stacker has allocated so much disk space on
      your primary MS-DOS partition for storing the Stacker volume
      file (SVF) that there is inadequate disk space to install MS-DOS
      6.2. To work around this problem, you must increase the free
      space on your uncompressed drive. For instructions on increasing
      the free space on your uncompressed drive, refer to your printed
      MS-DOS 6.2 documentation.

7. Q. I think that one of my MS-DOS 6.2 Upgrade disks is defective.
      What should I do?

   A. To determine if an original MS-DOS 6.2 Upgrade disk is
      defective, use the following steps:

      1. Copy the contents of the suspected defective disk to NUL. For
         example, type "copy /b a:\*.* nul" (without the quotation
         marks) at the MS-DOS command prompt and then press ENTER.

         This command forces MS-DOS to read all the files on the disk
         and copy them to the NUL device.

      2. If you receive an error message, such as "Data error reading"
         or "General failure reading," during the copy process, the
         disk is probably defective. To order a replacement disk, call
         Microsoft Sales Information Center at (800) 426-9400.

      If you do not receive an error during the copy process, the disk
      is probably not defective.

      For more information on troubleshooting setup, refer to your
      printed MS-DOS 6.2 documentation.
