    On similar lines, some time back, i read that, to accomodate large
    physical memory ,
    the 3G/1G layout is modified to have 4G/4G partition. But if somebody
    can focus the light on following things, it will be helpful.
    1) what was the requirement of 4G/4G layout ?
    2) how it is managed ?
    3) how HIGH_MEMORY concept is related here.

    Thanks in advance,
    Yogeshwar
