  12. Ok.  Ultra-simple assembler question for you guys...
  13.  
  14. In 386 assembler I need to fill an extended register with 4 copies
  15. of the same byte.  Right now I'm using the following:
  16.  
  17.    mov  al,VALUE
  18.    mov  ah,VALUE
  19.    shl  eax,16
  20.    mov  al,VALUE
  21.    mov  ah,VALUE
  22.  
  23. I'm curious... is there a better/faster way to stuff the register?
  24.
