Description
7
Hole Enable (HEN). This field enables a memory hole in DRAM space. Host cycles matching an
enabled hole are passed on to ICH3-M through the hub interface. The hub interface cycles matching
an enabled hole will be ignored by the MCH-M. Note that a selected hole is not re-mapped.
0
Disabled. No hole
