To remove these files type deltree /y c:\dblspace.* at the MS-DOS command prompt and then press ENTER. Also, use MS-DOS Editor to remove any DEVICEHIGH=C:\DOS\DBLSPACE.SYS /MOVE commands from the CONFIG.SYS file. After doing so, restart the computer with the Uninstall disk in drive A.

How to Return to MS-DOS 5.0 If Uninstall Fails

If you have not installed DoubleSpace, carry out the procedure on page 179 of the "Microsoft MS-DOS 6 User's Guide" to restore MS-DOS 5.0. If this procedure does not work, or if you have installed DoubleSpace, carry out the following procedure:

NOTE: Use this procedure only if you are restoring MS-DOS 5.0. If your previous version of MS-DOS is earlier than 5.0, do not use this procedure.

• To remove DoubleSpace and save your files, carry out the procedure in section 7.6 of the README.TXT file, which is in the directory that contains your MS-DOS files (usually C:\DOS).
• Use the SETVER command to specify to the Setup program that your computer uses MS-DOS 5.0. For example, type the following at the MS-DOS command prompt:

setver setup.exe 5.00


• Remove the read-only attribute from the COMMAND.COM file on drive C by typing attrib c:\command.com -r at the MS-DOS command prompt and then press ENTER.
• Restart your computer by pressing CTRL+ALT+DEL.
• Run the MS-DOS 5.0 Setup program.

How to Return to a Version of MS-DOS Earlier Than MS-DOS 5.0

To return to a version of MS-DOS earlier than MS-DOS 5.0, carry out the following procedure:

• If you have repartitioned your hard disk drive, you may be unable to see your partitions when you start your computer with a previous version of MS-DOS. If this is the case, you must do the following:


• Back up your data.
• Repartition your drive(s).
• Format your drives. Be sure to use the /S parameter when you format drive C.
• Restore your data.

• If you did not repartition your drive(s) after you installed MS-DOS 6.0, restart your computer with a system disk from your previous version of MS-DOS in drive A.
• If you can see all your partitions (using the DIR command), use the SYS command to transfer the MS-DOS system files to drive C. For example, type sys a: C: at the MS-DOS command prompt and then press ENTER.
• If the SYS command fails because it cannot find room on drive C, you can do the following:
• Use a third-party utility (such as Norton Utilities by Symantec) to make drive C bootable. -or-


• Use the FORMAT command with the /S parameter to reformat drive C and transfer the MS-DOS system files. For example, type format c: /s at the MS-DOS command prompt and then press ENTER.
WARNING: Using the FORMAT command erases all the files on drive C. If you back up your hard disk prior to formatting it, be sure to use a backup utility that is compatible with your earlier version of MS-DOS.
• Copy all the MS-DOS program files from the original MS-DOS disks to the directory that contains your MS-DOS files (usually \DOS).
