When the system runs with PAE disabled, drivers for 32-bit devices never require their map registers to be backed by real memory. This means that double-buffering is not necessary, since all devices and drivers are contained within the 32-bit address space.

- | To constrain compatibility issues, Windows XP Service Pack 2 includes hardware abstraction layer (HAL) changes that mimic the 32-bit HAL DMA behavior. The altered HAL grants unlimited map registers when the system is running in PAE mode. In addition, the kernel memory manager ignores any physical address above 4 GB.

As a result of these changes to the HAL and memory manager, the impact to device driver compatibility is expected to be minimal on systems running Windows XP Service Pack 2 with data execution prevention enabled. | As a result of these changes to the HAL and memory manager, the impact to device driver compatibility is expected to be minimal on systems running Windows XP Service Pack 2 with data execution prevention enabled. | ||
