The Set_Physical_HMA_Alias service defines an HMA alias for pages 100h
through 10Fh. This service is for the exclusive use of the XMS driver, a
part of the virtual V86MMGR device, and is only available during
initialization.

           physical HMA alias.

Comments
 
This service does not map new pages into the HMA. Instead, the virtual
device must call the _MMGR_Toggle_HMA service with the MMGRHMAPhysical value
after the calling this service. This service specifies which pages are
mapped when the MMGRHMAPhysical value is specified in a call to the
_MMGR_Toggle_HMA service.
