SubjectRe: can somebody explain how linux support 64G memory
There are two ways, the PAE flag and the PSE-36 feature introduced in
P3. These extensions are documented in the IA-32 Intel Architecture
Software Developer's Manuals, which you can find here:

http://developer.intel.com/design/Pentium4/manuals/

Look in Volume 3, Chapter 3 for this info.
