DOCUMENT:Q94569 23-NOV-1999 [msdos] TITLE :Compression Software Doesn't Load After Running MemMaker PRODUCT :Microsoft Disk Operating System PROD/VER:MS-DOS:6.0,6.2,6.21,6.22 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft MS-DOS operating system versions 6.0, 6.2, 6.21, 6.22 ------------------------------------------------------------------------------- SUMMARY ======= If you run MemMaker with a third-party disk compression program, such as Stacker or SuperStor, MemMaker cannot undo the changes in the CONFIG.SYS and AUTOEXEC.BAT files after a failed boot attempt. MORE INFORMATION ================ If a reboot attempt fails, MemMaker provides a Cancel button to undo changes. MemMaker attempts to undo all changes to your CONFIG.SYS and AUTOEXEC.BAT files on the host drive but cannot because the compressed drive in no longer mounted. Although MemMaker correctly detects compression on the system and verifies that the CONFIG.SYS and AUTOEXEC.BAT files match, the problem still occurs because CHKSTATE.SYS is loaded before the disk-compression software. MemMaker is able to restore the files on the host drive, but not on the compressed volume (which is swapped with the host AFTER the disk- compression software is loaded). To restore your computer to its previous state, copy and rename the AUTOEXEC.UMB and CONFIG.UMB files from the host drive to the compressed volume after you choose the MemMaker Cancel option. For example, if drive D is the uncompressed host drive and drive C is the compressed volume, use the following commands: copy d:\autoexec.umb c:\autoexec.bat copy d:\config.umb c:\config.sys Additional query words: 6.22 6.00 6.20 ====================================================================== Keywords : Technology : kbMSDOSSearch kbMSDOS621 kbMSDOS622 kbMSDOS620 kbMSDOS600 Version : MS-DOS:6.0,6.2,6.21,6.22 ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
