And that there are any bytes left over in the address space
to stick the new code into. (Of the two, recognizing the
JMP instructions is the more easily solvable. How many
different embedded controllers are in common use these
days? ID the controller and look it up, or try different
interpretations of the code until you find one that starts
making sense.)
