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
and be happy.
