My understanding of PAE (or AWE, as it's known in Windows) is that its only effect is to allow individual applications to use physical memory above 4GB--and the applications must be specifically coded to do so. I doubt that many are, since there are so few x86 systems with more than 4GB.
IOW, it won't suddenly turn your x86 system into a 6 or 8 GB machine. > So, does anyone know how I can find out if my OS is actually using all > 6gb of ram I put in it?
