# MS-DOS 6 Upgrade Setup /M Erroneously Updates SYSTEM.INI

## SYMPTOMS

After you perform a minimal installation of the MS-DOS 6 Upgrade (SETUP /M) on a system with Microsoft Windows 3.x or Windows for Workgroups 3.x, the following error message appears when you start Windows:
Cannot find a device that may be needed to run Windows in 386 enhanced mode.
You need to run the Setup program again.
c:\[directory]\vfintd.386
Press a key to continue..
At this point, the system stops responding (hangs).

## CAUSE

If you use SETUP /M, the setup program incorrectly updates the [386Enh] section of the Windows SYSTEM.INI file by replacing the line DEVICE=*VFD with the following

DEVICE=C:\<directory>\VFINTD.386

where <directory> contains the current MS-DOS 6.0 files.
Since the installation of Microsoft Backup for Windows is not included in a SETUP /M installation, the 386 enhanced mode virtual floppy device driver used by the utility (VFINTD.386) is not present in the MS-DOS 6.0 directory, causing Windows to generate the error message.

## RESOLUTION

To correct this problem, expand the file VFINTD.38_ from Disk 3 (in the 5.25-inch disk set) or Disk 2 (in the 3.5-inch disk set) of the MS-DOS 6.0 Upgrade disks to the MS-DOS 6.0 directory as VFINTD.386, or edit the SYSTEM.INI file, remove the line

DEVICE=[drive:directory]\VFINTD.386

and replace it with

DEVICE=*VFD.
