A part of the ACA1221 EEPROM is used to create an autoconfig, and we're trying to make a library available that handles setting CPU speed.

For the ACA1233, all features are available right from the start, but the ACA1221 will always start with 17,03MHz. That's a safety precaution, so a processor that isn't overclocking-stable will not keep you from using it from a cold-start and enter the refund code.

It's not a secret how to set a different CPU speed. We may either make that part of ACAcontrol open-source, or you'll implement a simple tool under Linux that does the job.

Brett already has it right:

Correct - the unprotect-jumper only needs to be set if a license is added or removed. Licenses are written into non-volatile memory and are still available if you remove the jumper and start up "cold".
