PAE solves this issue.

Becuase you've not exceeded teh 4gb maximum of 32-bit programming.

XP reserves so much ram per device, in order to be able to communicate with it...commands get cached within this "space". In the end it doesn't really matter, as most 32-bit programs are capped at 2gb of usable mem, so that windows and devices have what they need to operate.

But it's Virtual addresses...this is what Jazzman is talking about. Physical ram is different, and dealt with by bios.
