These are the most important opcodes you need to know to work with FS and GS 
in a 16-bit assembler:
0F A8        PUSH GS
0F A9        POP GS
0F B5 r/m    LGS
64           FS: prefix
65           GS: prefix
8C r/m       MOV r/m,segreg --> r/m bits 3-5 = 100 for FS, 101 for GS
8E r/m       MOV segreg,r/m --> dito
greetz,
