Hello

The newer addressing mode is the 3-level page tables available in PIIIs (and in later stepping PIIs, I think), which allow transparent access to all of physical memory up to 64G. That's what I'm aiming for.
AFIAK it's the other way around:
the 3-level system is PAE, available since PPro, and the 2-level system where only 4 MB PTE's can address memory > 3 GB is the new system added for the P-II Xeon. I think this mode was only added for WinNT:
Intel wants to support > 4 GB memory,
but the internal MM of NT is 2-level even in Windows-2000. (according to www.osr.com).
Have you already started with your high-mem patch?

Not really -- the bulk of the work is waiting until journaling is done.
