I thought the deal with lock bits once they were programmed was that the only way to unprogram them is via a chip erase?
What are the 6 lines of code needed to get avrdude able to work under the Arduino IDE with the Dragon? It's just for SPI programming mode, I'd guess, or can it be configured by avrdude options to do HV programming as well?
Anyway, thanks for your help. How come lots of people aren't doing this???
