there are a number of atoms the support 64bit, I think that the observation I was making was that there are atoms that don't support PAE, by virtue of not supporting 4 or more GB of ram. > >> There are plenty of machines that do. virtually every intel system since >> the pentium pro (except the atom) has the hardware if not the bios >> support for doing so, that's not germain to the question of whether it's >> feasible/useful in an embedded system.
