   Thanks for the info. In my case I want the .com file   
   to be a boot loader. I wish to use SubC which produces   
   small memory model and was wondering what restriction   
   that caused compared with tiny.   
      
   Thanks for showing the code, but I think there is an issue   
   with it.

   I don't think you want this add of 10h. You have   
   already done that once. You don't want to do it   
   again.

   Ditto.
