This is the great thing about the Archos units.
You put the new f/w on the disk, and the flashed f/w
just runs it like a program.
If the program is stuffed, then you simply erase the file
and go back to the original flashed code.
If you have to flash the chip each time, you may like to
consider alternative ideas.
