SUMMARY
To completely reinstall MS-DOS 6.22 from the Step-Up disks, you must first reinstall the version of MS-DOS that was on the system prior to MS-DOS 6.22. This process can become complicated if the drive containing the MS-DOS directory has been compressed using DriveSpace.

The only supported method for reinstalling the MS-DOS 6.22 Step-Up on such systems is to uncompress the drive containing the MS-DOS directory before proceeding with the reinstallation of the prior MS-DOS version.



MORE INFORMATION
To reinstall MS-DOS 6.22 Step-Up on a system whose MS-DOS directory is located on a DriveSpace-compressed drive, use the following steps:


 * 1) Uncompress the drive containing the MS-DOS directory.
 * 2) Run Setup with the /F parameter to create a single startup floppy disk that contains system files from the version of MS-DOS that was on the system prior to MS-DOS 6.22.
 * 3) Boot from the startup disk made in step 2.
 * 4) Reinstall the prior version of MS-DOS by running "setup" (without the quotation marks) from Setup Disk 1.
 * 5) Run the MS-DOS 6.22 Step-Up.
 * 6) Recompress the drive containing the MS-DOS directory (if desired).
