I too am VERY interested in the inside of the CODE segments.
Unfortunately neither the TechNotes nor IM have very much to say
(other than you cannot have more than (4096-x, x== ?) jump table
entries. (The jump table entries contain code for loading a segment
and junmping. In EIGHT BYTES ? What code ?

PLEASE, do ! I've been pulling my hair but decided that "It's probably
of no use"... But now that other people as well have asked, my curiosity
is KILLING me !

Happy Hacking !
