   while you have your own OS (even a fictive one yet) then   
   you can use just one single GETMEM variant like I use in   
   my OS:   
      
   getmem:   
      
   called by RM16 or PM32 entry points or INT7F for both   
      
   input:AL=mode 0=seg:offset  1=32bit flat   
          ECX= requested size in bytes   
      
   returns:   
          Carry+Z size not available, Cy+NZ no more handles   
          No Carry: means no error, then   
          BX=handle mode0 EDI=flat start   
                    mode1 ES:DI = start   
      
   and yes, the flat mode works for RM16(unreal) as well.
