Hi all:

on booting of x86
top of file arch/x86/boot/pmjump.S
there is code
-------------------
GLOBAL(protected_mode_jump)
        movl    %edx, %esi
        xorl    %ebx, %ebx
        movw    %cs, %bx
        shll    $4, %ebx
        addl    %ebx, 2f
...
-------------------

what's the value of %cs here? how was it loaded?
i would really appreciate if someone provide me some references
thank you very much
