You seem to have a problem with your attitude Dennis. PAE mode is what I
was talking about, it is an ADDITION to a 32 bit system. As I recall we
were talking 32 bit addressing originally. In general 32 bit has a
physical and mathematical limit of 4GB. Whether MS chose to use it or
not, the fact that PAE could have been used does not change this fact. I
was not being confrontational, rather the opposite in fact, nor did I
make the original statement, however I think for practical purposes
saying that a 32bit OS can only support 4GB is true enough for most
situations, Anything over that in my opinion is an addition or workaround.

I'm not the one with an attitude. This entire discussion is about PAE
and what is possible in PAE mode. Both XP and Vista includes a PAE
kernel, and in PAE mode, you can use more than 32 bits to define the
physical address. Microsoft just choose not to use any additional bits
to address memory, but it is a choice, not something that is
mathematical impossible.
