However, "client" versions of 32-bit Windows (Windows XP SP2 and later, Windows Vista, Windows 7) limit physical address space to the first 4 GB for driver compatibility  via the licensing Do not call MmGetPhysicalAddress() on a locked buffer, discard the high 32 bits, and then program the adapter to DMA into the resultant address.

Requiring all drivers to use IoGetDmaAdapter would create enormous test and performance issues. RAM is like short term memory. For example, on a Windows 2000 Advanced Server system with 8 GB of physical memory, a database server application could use AWE to allocate and use perhaps 6 GB of memory

To me it is quite annoying that MS doesn't support PAE in Windows desktop OSs as a feature - probably just because they don't want to support it in their documentation, Note about the PAE switch: I didn't specifically turn it OFF in boot.ini.
