   I can't recommend to do this!   
      
   endless:   
   LES BX,[SI]  ;SI=?? may depend on environment   
   LAHF         ;who knows what's in the flags ?   
   STOSW        ;WRITE to ES:DI (try to use cc-flags for color)   
   INC DI dup2  ;stosw does this also   
   JMP $-7      ;endless or until crash   
      
   BX isn't used.   
   And if SI doesn't point to the screen-seg it writes to another 64KB block.
