It all depends on who defines the support matrix. Well, maybe. I mean, the CPUs all have PAE (in 32-bit mode) and thus can use 36-bit physical addressing these days (or more in the case of amd chips). > The other way is to reassign "invalid" resources (above 4GB) with > "valid" ones (below 4GB).

I originally thought Windows probably allowed the larger addresses and use PAE but that might not be the case at all.
