However, careful device driver development is still required. Enable Pae Windows Xp p.439. The 32-bit size of the virtual address is not changed, so regular application software continues to use instructions with 32-bit addresses and (in a flat memory model) is limited to 4gigabytes

PAE is supported only on 32-bit versions of the Windows operating system. 64-bit versions of Windows do not support PAE. Microsoft. To disable DEP, use the /EXECUTE switch. On such systems, booting with 4GT enabled causes the operating system to ignore any memory in excess of the limit.

If the computer does not support hardware-enabled DEP or is not configured for hot-add memory devices in memory ranges beyond 4 GB, PAE must be explicitly enabled. Tests using extreme memory pressure--whenever IRQL or spinlock is acquired, try to page out the driver; catches fatal errors. Here is my boot.ini entry: 'multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Windows Server 2003, Enterprise" /NoExecute=OptOut /fastdetect /PAE' (without the single quotes, of course).
