Hi Rod,
The short answer: I don't know. I haven't heard of any such plans; but then
I'm certainly not on any inner-circle discussions on this matter.
Microsoft don't appear to actively monitor his newsgroup, so to make
Microsoft aware of the matter, send feedback via:
http://feedback.windowsvista.microso...p_vista_master
That way, at least they get to hear your experience (which I sympathise
with, btw).
My unsubstantiated speculation is that it is very unlikely full-screen
support will be added, anytime soon.The question came up several times
during the Vista beta. There was some deep technical reason, why it wasn't
feasible for WDDM drivers to support the full range of VGA Int10 modes. It
wasn't merely a "it's loo much work, lets drop it" kind of decision.
Besides (not to defend their decision, but ...) it was probably expected
that POS systems would generally be lower-end hardware; and running Windows
Embedded or some similar cut down version, rather than the full Vista
desktop:

The restriction on full-screen DOS apps is a function of the WDDM driver
model; it isn't intrinsic to Vista itself. To put that another way: if you
run Vista *without* a WDDM display driver, there should be no problem
running DOS apps, full screen. WDDM is the new driver model introduced
alongside Vista to support Aero, 3D, multimon etc. The "old" graphics driver
model - as used in 200, XP and Server 2003 - continues to work in Vista.
Microsoft have labelled this pre-WDDM driver model "XPDM" (XP Driver Model)
in retrospect.
So, two short-term workaounds might be:
- locate and deploy a non-WDDM, XPDM Vista display driver for your hardware.
Intel, for example, was late in getting WDDM drivers to market so had a
bunch of XPDM drivers (basically rebadged XP drivers) for Vista when it
first came out. Other graphics vendors may have similar non-WDDM drivers
available.
- try running with XP video drivers. This is unfortunetaly getting into
unsupported territory. But, you can certainly run Vista with an XP video
driver.
Basically, if you can get away from WDDM video drivers, then Vista itself
has no problem running full-screen DOS applications.
Hope it helps,
