   I have no idea what you are talking about. Some applications   
   exceed the capacity of a 2 GiB/4 GiB address space, and the   
   cleanest solution to that problem in the absence of 64-bit   
   registers is segmentation.   
      
   You just need to recompile your application in the compact   
   memory model and the job is done.
