Full-Screen DOS Mode in Vista

[A Black Falcon]

Anyway though, I find it fascinating that Vista doesn't have fullscreen DOS mode because Microsoft removed it, but because NVidia removed it. Well, Microsoft probably encouraged them to, but what other explanation is there for the fact that the basic Microsoft video driver works with fullscreen DOS mode while NVidia's drivers do not?

Also, my point pretty much was that I wouldn't expect a DOS program to be able to see a Windows service. That just doesn't quite make sense... what would it do then running in real DOS mode instead of a window?
