Vista - Full Screen Mode not Available in this System with CMD

Hello,

We have some 16-bit legacy apps which must run in a DOS box window
with CMD.EXE. When I try to run them I get the following message:

Full Screen Mode not Available in this System


I cannot use Alt-Enter to make the screen full size. I need INT 10h
and VESA functions.
Is there any hope in getting this to work with Vista Premium?

Thanks
Mike McWhinney

It was my understanding that the Vista cmd prompt is now 32 bit,
and can't run 16 bit programs. I don't know that definitely, but I
seem to remember reading that somewhere.

Vista 32-bit can't run full screen 16-bit/DOS programs. It can,
however, run most other 16-bit/DOS apps. Vista 64-bit cannot.

To the OP, you may be able to get your apps to run in a virtual machine
or DOS emulation environment, like DOSBox.

Best regards,

Dave

You need to instal XP (XDDM) video drivers to get full screen in a
command prompt in Vista. If you are using Vista (WDDM) video drivers
then you will not be able to use a full screen command prompt unless
you use a program like solvbe or equivalent to intercept INT10. (WDDM
drivers do not allow INT10 access).

So install the XP drivers (and have XP level video driver stability)
and be happy.

With the caveat that one won't have Aero... not that that matters... just an
observation.
