Here's the codes:
   {#C7,#04,#00,#00,#00,#00,#FF,#FF,#FF,#FF}--mov dword ptr [0],
#FFFFFFFF
   {#66,#C7,#04,#00,#00,#00,#00,#FF,#FF}--mov word ptr [0], #FFFF
   {#C6,#04,#00,#00,#00,#00,#FF}--mov byte ptr [0], #FF
Just poke your address over the #00's and your immediate over the #FF's,
or build the sequence like
   {#C7,#04} & int_to_bytes(address) & int_to_bytes(immediate)

I hope this works for ya.
