This register provides the starting address of the Graphics Aperture Translation Table Base located in the
main DRAM. This value is used by the MCH-M Graphics Aperture address translation logic (including
the GTLB logic) to obtain the appropriate address translation entry required during the translation of the
aperture address into a corresponding physical DRAM address. The ATTBASE register may be
dynamically changed.
Note:
The address provided via ATTBASE is 4-KB aligned
.

Aperture Translation Table Base (TTABLE):
This field contains a pointer to the base of the
translation table used to map memory space addresses in the aperture range to addresses in main
memory.
NOTE
: It should be modified only when the GTLB has been disabled.
