PAE paging

Post by madanra »

Hi, I'm researching how paging (with & without PAE enabled) works, but I'm unable to find a complete bitmap of the 64-bit page directory/page table entries when PAE is enabled. I found one page with a bitmap for the entries, but it didn't include the extra flags such as execute disable.
Part of my problem in finding info on PAE is that this page (http://wiki.osdev.org/Setting_Up_Paging_With_PAE) exists, yet if you search the wiki for PAE (http://wiki.osdev.org/Special:Search?search=pae) no results are returned, which is odd.
