I'm pretty sure that not all the drivers(especially graphic ones) fully support PAE. Server versions of PAE would be much easier to support than making sure drivers for win32 would be compatible in a PAE environment. See http://msdn.microsoft.com/en-us/library/windows/hardware/gg4... Typically, device drivers must be modified in a number of small ways. Although the actual code changes may be small, they can be difficult. This is because when not using PAE memory addressing, it is possible for a device driver to assume that physical addresses and 32-bit virtual address limits are identical. PAE memory makes this assumption untrue. |
