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
