Dude. How do I put this? Oh, right, that's it: "Shut up. Brett has forgotten more about computer architecture than you'll ever know." You should really cease and desist before you embarrass yourself further. The PAE mode in the x86 MMU provides 36 bits of address space to the kernel only. User processes are limited to, at best, 4GB of virtual space; pretty much the _only_ thing PAE mode does is offer the possibility of providing more physical space to back them. Unfortunately, as I doubt you understand the difference between a virtual address and a virtual girlfriend, I suppose this will be lost on you. Thor
