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.
