    Hi All,

    I want to understand how to access above 4GB memory using PAE
    mechanism. I need some sample code which helps me to understand

    1. How to enable PAE
    2. How to setup page table for accessing above 4GB
    3. How to read and write the memory more than 4GB.

    Any help is greatly appreciated. Even some reference books also very
    much helpful.

    Thanks,
    Raja
