In every piece of IFI equipment that i have had the opportunity to void the warranty on, I have noticed a small 5 pin .1" pinheader. I believe this to be an ICSP header. The number of pins match. ICSP is a standard interface for programming pic microcontrollers in circuit using a programming tool. I strongly believe that this is how they change the firmware. There may also be a second way of programming the OI through the serial port(dashboard) that they are not telling us about. I have not had an opportunity to take apart a 2004 OI but i'm pretty sure that when i do this is what i will find. Actually now i am curious. I wonder if they have enabled code preotection. If not it would be possible to download the firmware from the OI, disassemble it, and hack the OI to do evil things. ::devious grin::
