PAE sucks and can be a big pain to implement.
bandaid solution to crappy engineering. idiots should have thought of using 36 bit addresses from the beginning.
it is impossible for windows xp 32 bit to recognize 4GB of ram, 2^32 = 4GB. Google url=http://msdn.microsoft.com/en-us/library/aa366778%28v=vs.85%29.aspx#physical_memory_limits_windows_xp]32bit OS ram limitation.[/url]
Microsoft then decided to hide this problem with SP3, Device Manager now shows 4GB because it now reports installed RAM and not usable RAM.
Typically you get access to 3.25 of 4GB. The 'missing' RAM is reserved for windows and system stuff. However, it can be as low as 2.5GB if you have a lot of peripherals.
That being said you can use more than 4GB in a 32 bit system, if you use the extra RAM as a ramdisk.
