Yeah, I've tried the "Use unprotected checksum" feature on the chips we use
that have theses ID locations (The majority of the chips we use do not have
ID locations). I've had less than impressive results using the "Put the
checksum into the ID locations" on 12c508A's - we eventually gave up. IIRC
the checksum displayed by MPLab and the checksum poked into the ID locations
is calculated differently.

I haven't tried this for at least a year or two. Maybe it works different
now - or maybe I was doing something wrong. I'll give it another shot when I
get some time.
