PAE High Memory in Backtrack Linux
Here is a step by step guide to enabling the high memory kernel module in backtrack Linux.
This is what you need if you want to utilize the wasted memory while running in your favorite Penetration Testing Distribution!
We all want to get as much power out of our operating systems as possible and that goes double for penetration testers.
Use this simple tweak to enable an extra Virtual Machine or some much needed password cracking.

#It is a very simple kernel mod that allows the utilization of more memory
#under my favorite security testing distro.
#Things can and do go wrong but if your looking for this kind of tweak you
#are willing to get your hands dirty. I will walk you through updating the kernel
#for both a live distro and your personal iso. The iso can then be modified to
#include the tools you personally require and install.
#I use the iso update method to make several kernel tweaks and add all of my
