Are these not the EQU statements in the code that you uncomment by 
removing the ";" in front of the one you want?

Oh, config for the particular chip used?

Again, I'm not (yet) familiar with the development and compiler to know 
what's required.

I don't understand what's so difficult about removing the chips from the 
board and programming them in a $7 socket connected to the 4 or so 
programming wires from the PICKit3.
