physicalMemoryDeviceSize

This attribute defines the size of the memory device in MB.  If the value 
is 0, no memory device is installed in the socket.  if the size is unknown, the field
value is FFFFh. The granularity in which the value is specified depends on the setting
of the most significant bit, bit 15.  If the bit is 0, the value is specified in megabyte
units;  if the bit is 1, the value is specified in kilobyte units.  For example, the value
8100h identifies a 256KM memory device and 0100h identifies a 256MB memory device.
