Rather than just a <press A, press B,..> description, I need a hardware-engineer's theoretical explanation. Like: to get the battery-powered rPi, with no display nor input, to boot into playing a sequence of *.wav; you can bypass the login, and set the initial 'task', by editing /etc/inittab and what imediately follows. And then to navigate the selection of files played with no input, except the powerswitch, you [time modulate] cut the power at 'selected times'. Yes, I admit, it's easy to forget the details [that's why the Chinese invented writing], but if someone understood the underlying principles, of 'jailbreaking an ereader',they could explain them. IMO most of the code would be in ROM and therefore in-accessable. WDYS?
