DOCUMENT:Q121794 21-NOV-1999 [msdos] TITLE :Reinstalling MS-DOS 6.22 Step-Up with DriveSpace Installed PRODUCT :Microsoft Disk Operating System PROD/VER:MS-DOS:6.22 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft MS-DOS operating system version 6.22 ------------------------------------------------------------------------------- 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).
