    LFS loads into two registers the 32-bit pointer variable found in
    memory at source. LFS stores the segment value (the higher order word
    of source) in FS and the offset value (the lower order word of source)
    in the destination register. The destination register may be any any
    16-bit general register (that is, all registers except segment
    registers).

------------------------------------ Timing ----------------------------------

OpCode          Instruction             386     286     86
0F B4/r         LFS r16, m16:16         7       7
0F B4/r         LFS r32, m12:32         7

------------------------------------ Logic -----------------------------------

        FS = (Source + 2)
        destination = (source)
