This information applies to both Microsoft DoubleSpace and Microsoft DriveSpace. For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands and filenames.
SYMPTOMS
If you try to upgrade to MS-DOS 6.2 while you are running AddStor SuperStor, you may receive the following error message:
CAUSE
SuperStor maintains two copies of the CONFIG.SYS and AUTOEXEC.BAT files: one on the compressed drive and the other on the uncompressed drive. If these files are not identical, you receive the above error.
RESOLUTION
To make the CONFIG.SYS and AUTOEXEC.BAT files identical on both the compressed and uncompressed drives, do the following:
If the compressed drive (C in this example) has the more current versions of the CONFIG.SYS and AUTOEXEC.BAT files:
- Delete the CONFIG.SYS and AUTOEXEC.BAT files from the uncompressed drive (D in this example) by typing:
del d:\config.sys
del d:\autoexec.bat - Copy the CONFIG.SYS and AUTOEXEC.BAT files from the compressed drive to the uncompressed drive by typing:
copy c:\config.sys d:\config.sys
copy c:\autoexec.bat d:\autoexec.bat - Run SETUP again.
If the uncompressed drive (D in this example) has the more current versions of the CONFIG.SYS and AUTOEXEC.BAT files:
- Delete the CONFIG.SYS and AUTOEXEC.BAT files from the compressed drive (C in this example) by typing:
del c:\config.sys
del c:\autoexec.bat - Copy the CONFIG.SYS and AUTOEXEC.BAT files from the uncompressed drive to the compressed drive by typing:
copy d:\config.sys c:\config.sys
copy d:\autoexec.bat c:\autoexec.bat - Run SETUP again.
MORE INFORMATION
In most cases, the copies of the CONFIG.SYS and AUTOEXEC.BAT files on the compressed drive are more current than those on the uncompressed drive. To verify this, do the following:
- Go to the uncompressed drive (usually drive D) by typing D: at the C:\> prompt.
- At the D:\> prompt, type dir config.sys and write down the date of this file. Then type dir autoexec.bat at the D:\> prompt and write down the date of this file if one exists.
- Now go to the compressed drive (usually drive C) by typing C: at the D:\> prompt.
- Again, check the date of the CONFIG.SYS and AUTOEXEC.BAT files using the process outlined in step 2.
