Is there any way to get/set these raw settings (like, whatever it has in EEPROM)?

I expect we may ship some of these systems overseas, and would like the flexibility
to set the country-code for testing purposes, if nothing else.

Is there any documentation as to what '98' really means, or do we just ignore that
value and look at the info printed out after that?

Thanks,
Ben
