MS-DOS Setup May Corrupt VxD Command in SYSTEM.INI File PSS ID Number: Q106096 Article last modified on 11-05-1993 PSS database name: O_MSDOS



The information in this article applies to:
- Microsoft MS-DOS operating system version 6.2


After you install MS-DOS 6.2 and the optional Windows-based programs, you may be unable to run Windows.


This problem occurs when a virtual device driver (VxD) for Windows fails to load due to a problem in the SYSTEM.INI file.

If a third-party program places its device=<VxD> statement between the MS-DOS “Setup Modification” comments in the SYSTEM.INI file, the device statement may be corrupted when MS-DOS 6.2 Setup updates the SYSTEM.INI file.


To work around this problem, edit the backup copy of your SYSTEM.INI file (called SYSTEM.620) and note the correct device= statement for your third-party VxD. Edit your current SYSTEM.INI file and add that statement to the [386Enh] section.
