I should rephrase for him. TRUE dos support is non-existant anymore. This started with Windows XP. ntvdm as you described is a virtual dos machine which means it emulates dos. Windows ME restricted access to it (you couldn't actually get to a true dos mode). The whole original Windows NT line was without any dos support at all. Not even emulated. Check cmd versus command sometime in XP. You will note that even the dir command is slower in the ntvdm than it is in a native prompt. > >> (And now if I could only get people to stop incorrectly referring to a >> NT/2k/XP/Vista command prompt a DOS prompt... and I also want a pony.) > > You don't think big enough. :) I want a percheron-thoroughbred cross > like my last good buddy of that lineage-- 2,000 lbs. worth of quiet > friendship... > Wha?
