DOCUMENT:Q111459 25-NOV-1999 [msdos] TITLE :CONFIG and AUTOEXEC on Compressed and Host Drive Do Not Match PRODUCT :Microsoft Disk Operating System PROD/VER:MS-DOS:6.2,6.22 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- 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.
