LGS loads into two registers the 32-bit pointer variable found in
memory at source. LGS stores the segment value (the higher order word
of source) in GS 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).
