You may find that some 16-bit DOS-based programs do not run in full-screen mode in Windows Vista and in Windows 7. You cannot set a Command Prompt (CMD) window to display in full-screen mode.
Note This symptom only applies to 32-bit versions of Windows Vista and of Windows 7. 16-bit programs are not supported on 64-bit versions of Windows Vista or of Windows 7.
The issue occurs because the Vista device drivers do not support running all of the DOS video modes. The Vista device drivers are based on the Windows Vista Display Driver Model (WDDM).
You may be able to work around this problem by installing the Microsoft Windows XP version of the video drivers for your video adapter. Contact the manufacturer of your video adapter for more information about how to obtain the Windows XP version of the video drivers for your video adapter.
