LGS               Load Far Pointer in GS (386)       Flags: O D I T S Z A P C

LGS destination register, memory operand

           Logic:        GS . SEGMENT(memory operand)
                         destination register . OFFSET(memory operand)

     This instruction loads the segment address of a far pointer into GS and
     the offset address of pointer into the indicated destination register.

        Note:          The size of the source and destination operands
                       must be the same as the current segment word size.
