Someone more knowledgable here may correct me, but I'm not sure if gas
supports these
instructions (or any that are targetted for segment registers really).  You
could look at sys/farptr.h to
see an example of how the DJ code loads a segment register and then uses a
segment register override prefix.  Basically, a mov to a segment register
works but you must use a db to specify the prefix.

>a list of most of the instruction set for assembly
Its pretty much the same.  Just remember the size suffix.
