Tanks :)

But, other ask... Ok , the CS point to the last accessible segment, and
IP to the  last addess less  16 bytes...
What I do not understand is, how the bios data go to there  (may be
funny to you, so I dont find nothing documentation about)...
I ask it because a common bios have 256k and the segment which the
processor point is  752Kbytes far...
... so I guess I am not imagining right.
