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.
