摘要：
A method is provided for testing the entire memory address range of memory in a computer system having a Cpu supporting 32-bit or 36-bit memory addressing. If the CPU supports 36-bit addressing a page directory is created containing entries that support accessing the memory according to a maximum page size supported by the processor. If the processor supports 32-bit memory addressing, a page directory and one or more page tables are created for accessing the memory according to a maximum page size supported by the processor. Once the page directory and page tables have been created, they are utilized to access and test a portion of the memory. The page directory and page tables are then dynamically modified to allow access to other portions of the memory.
