1. Q. When I run the Setup program for the MS-DOS 6 Upgrade, my video
display is unreadable; either the instruction lines are
truncated or the screen text is unreadable. How can I correct
A. If you are currently running a version of MS-DOS earlier than
6.0 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 function key twice.
2. Insert Setup Disk 1 in drive A or drive B. At the MS-DOS
command prompt, type the following command and then press
where "drive" is the letter of the drive containing Setup
Disk 1. 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. For instructions on how to do this,
refer to pages 196-197 in the "Microsoft MS-DOS 6 User's
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 file, 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. To do this,
type the following at the MS-DOS command prompt and then
where "drive" is the disk drive on which you are creating
the temporary directory, and "directory" is the name of that
directory. For example, to create a temporary directory
named TEMP on drive C, type the following at the MS-DOS
command prompt and then press ENTER:
2. Use the COPY command to copy all files from the MS-DOS 6
Upgrade disks to the temporary directory. To do this, insert
Setup Disk 1 in drive A or drive B. At the MS-DOS command
prompt, type the following command and then press ENTER
copy drive:\*.* destination
where "drive" is the floppy disk drive containing Setup Disk
1 and "destination" is the drive location and directory name
of the temporary directory.
For example, if Setup Disk 1 is in drive A and you are
copying to the TEMP directory on drive C, type the following
copy a:\*.* c:\temp
Repeat this step for each MS-DOS 6 Upgrade disk.
3. Run the Setup program for the MS-DOS 6 Upgrade from the
3. Q. Can I install the MS-DOS 6 Upgrade on my IBM(R) PS/1(R)
A. You can upgrade to MS-DOS 6 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 the section titled "Your computer is an
IBM PS/1, and you cannot start MS-DOS" on pages 203-204 in the
"Microsoft MS-DOS 6 User's Guide."
4. Q. Can I install the MS-DOS 6 Upgrade on my Tandy(R) computer?
A. You can upgrade to MS-DOS 6 if you have a Tandy computer;
however, if you have one of the Tandy computers listed below,
it is possible that your computer uses ROMDOS, which must be
disabled before you can install the MS-DOS 6 Upgrade. Methods
for disabling ROMDOS vary depending on the model of Tandy
computer you have. For instructions on disabling ROMDOS,
contact Tandy Technical Support.
5. Q. I am using the Stacker(R) disk-compression program. When I run
MS-DOS 6 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
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. To work around this problem, you must increase the free
space on your uncompressed drive. For instructions on
increasing the size of the uncompressed drive, refer to page
186 in the "Microsoft MS-DOS 6 User's Guide," consult your
Stacker documentation, or contact STAC Electronics Technical
6. Q. I think that one of my MS-DOS 6 Upgrade disks is defective.
What should I do?
A. To determine if an original MS-DOS 6 Upgrade disk is defective,
use the following steps:
1. Insert the disk that you suspect is defective in drive A or
drive B. At the MS-DOS command prompt, type the following
command and then press ENTER
copy drive:\*.* nul
where "drive" is the letter of the floppy disk drive
containing the disk.
This command forces MS-DOS to read all the files on the disk
and copy them to the NUL device.
When NUL is used as a device for testing purposes, files
copied to it are discarded without being written to the
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 Consumer Sales at (800) 426-
If you do not receive an error during the copy process, the
disk is probably not defective. If you continue to encounter
problems while installing the MS-DOS 6 Upgrade, refer to the
"Diagnosing and Solving Problems" chapter in the "Microsoft
MS-DOS 6 User's Guide." This chapter addresses a number of
issues that can cause problems during Setup.
7. Q. I want to upgrade my Digital Research(R) DOS (DR DOS)
installation to MS-DOS 6. How should I do this?
A. You can upgrade from DR DOS to MS-DOS 6; however, before you
run Setup, you should first review the following precautions
and carry out those applicable to your system:
- If you have any security features, including password
protection, disable them. For more information, refer to
page 187 in the "Microsoft MS-DOS 6 User's Guide."
Warning: The MS-DOS 6 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 is password protected, use the DR
DOS PASSWORD command to disable password protection before
you install MS-DOS 6.
- If you have the DELWATCH delete-protection program installed
on your computer, you must disable DELWATCH and purge your
deleted files before you install MS-DOS 6. For the procedure
to do this, refer to pages 187-188 in the "Microsoft MS-DOS
6 User's Guide."
- 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.
- If your CONFIG.SYS file contains the DR DOS CHAIN command,
remove it and adjust the other CONFIG.SYS commands
- If your computer uses disk compression, but drive C is not
compressed, run Setup as described in the "Getting Started"
chapter of the "Microsoft MS-DOS 6 User's Guide." When Setup
displays the message "Your CONFIG.SYS file contains commands
that are not valid MS-DOS commands," select the Modify
Original Files option.
- If your hard disk is compressed, carry out the procedure in
the section of the README.TXT file titled "Setup detects
that your computer uses DR 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
(TM) (SSTOR) compressed drive to an MS-DOS 6 DoubleSpace
drive using the procedure below. This is necessary because
the DR DOS 6 SuperStor utility does not provide the
functionality for increasing the size of your uncompressed
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 Setup Disk 1 in drive A or B and use
the SETUP command with the /f switch. For example, if you
insert Setup Disk 1 in drive A, type the following at the
MS-DOS command prompt and then press ENTER:
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
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
format c: /s
5. Use the MS-DOS 6 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 Upgrade, run DoubleSpace to
compress your hard disk, and then restore your files.
After you finish restoring your files, continue with
6. To remove your DR DOS files, install the MS-DOS 6 Upgrade
again. To do this, insert the MS-DOS 6 Setup Disk 1 in
drive A, type "setup" (without the quotation marks), and
follow the instructions on your screen.
