POST Screen Display of Physical versus Logical Processors
Physical is implied when the count of processors is stated on the BIOS POST screen. The processor count should refer to logical processor count only if explicitly stated. The system BIOS should recognize two logical processors, but only one physical processor. Intel® Desktop/Server Boards supporting Hyper-Threading Technology will display only one physical processor during POST.
