This is the most commonly used mode. In this mode, the PAT performs a translation of each 4-KiB page individually. In this way the 128-MiB virtual address space can be scattered in the whole 2 GiB of the physical address space. This is achieved by using a 32,678-word LUT that converts each page index (32,768 possible values) into 19 address bits that represent this page address in the physical memory. The main characteristic of this mode is there is no constraint on the use of the physical memory except that it is uses a multiple of 4-KiB areas located at 4-KiB boundaries in the physical memory. In this mode, the translation vector is in the internal 32-k entry PAT vector table at the index given by bits [26:12] of the input virtual address, and CONT_x = 0.
