Please don't post about things that you don't understand. Here's the
information from Wikipedia:

http://en.wikipedia.org/wiki/Physical_Address_Extension

And here's the first four lines:

----------------------

Physical Address Extension
From Wikipedia, the free encyclopedia

In computing, Physical Address Extension (PAE) is a feature to allow
32-bit IA-32 central processing units (CPUs) to access a physical address
space (including random access memory and memory mapped devices) larger
than 4 gigabytes.

I've copied port-i386 on this in case more questions come up.
