For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands and filenames. When you have an MS-DOS 6 DoubleSpace-compressed C drive and you install MS-DOS 6.21 Upgrade, Setup installs the MS-DOS files on the host drive for C. As a result, you receive the following error message when you restart your computer after MS-DOS 6.21 is installed: wrong dblspace.bin version When this occurs, your compressed drive is left unmounted. CAUSE ===== This problem occurs when you boot your computer from the MS-DOS 6.21 Upgrade Disk 1, exit Setup (BUSETUP.EXE), and then try to run Setup (SETUP.EXE) from the A prompt. RESOLUTION ========== To correct this problem: 1. Uninstall MS-DOS 6.21 Upgrade. 2. Boot your computer from drive C. 3. Run MS-DOS 6.21 Upgrade Setup from Setup Disk 1.
