Adding to that,clearly, there is some misunderstanding you have about the real mode and protected mode. Protected mode is not *only* to have virtual addressing, its for 32 bit addressing scheme as well. Real mode is a 16 bit addressing thing with 20bit address bus. hope reading the history of intel machines explains this clearly. http://en.wikipedia.org/wiki/Protected_mode Regards Srinivas Bakki
