The information in this article applies to:
- Microsoft MS-DOS operating system versions 6.2, 6.22
-------------------------------------------------------------------------------
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:
Error: Setup cannot install MS-DOS on your computer. The copy of the
CONFIG.SYS or AUTOEXEC.BAT file on your compressed drive does not match the
corresponding file on your uncompressed drive
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:
1. 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" (without the quotation marks)
2. 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" (without the quotation marks)
3. Run SETUP again.
If the uncompressed drive (D in this example) has the more current versions of
the CONFIG.SYS and AUTOEXEC.BAT files:
1. 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" (without the quotation marks)
2. 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" (without the quotation marks)
3. 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:
1. Go to the uncompressed drive (usually drive D) by typing "D:" (without the
quotation marks) at the C:\> prompt.
2. At the D:\> prompt, type "dir config.sys" (without the quotation marks)
and write down the date of this file. Then type "dir autoexec.bat" (without
the quotation marks) at the D:\> prompt and write down the date of this
file if one exists.
3. Now go to the compressed drive (usually drive C) by typing "C:" (without the
quotation marks) at the D:\> prompt.
4. Again, check the date of the CONFIG.SYS and AUTOEXEC.BAT files using the
process outlined in step 2.
