BIOSSubMod()

         Returns the computer submodel

    Syntax:

         BIOSSubMod() -> nSubModel

    Description:

         Returns a number between 0 and 255, that is to say, the decimal
         value of a byte indicating the SubModel of the computer. This
         value is the one that normally is used by the majority of the
         manufacturers to distinguish their equipment. The worst case is
         a lot of clones manufacturers may use the same values. Is not the
         same with IBM, Compaq or Toshiba who use exclusive values.

         A numeric value indicating the computer submodel.
