Master Reset

I'm sure that you have seen those devices that allow you to do a master reset.· When you reset them they delete all the information that you stored and reset the initial set-up where they may have asked some questions to set the device up for the user.
·
Is this type of reset done with hardware, software or both?· ·Is it possible to have this type of reset in code only or do you have to load it from another eeprom maybe?
·
Thanks for your time.

    Usually the only hardware is the pushbutton that's used to signal the device that you want a complete reset. Everything else is done in software. The routine that does it probably just resets a specific location in EEPROM to it's initial value set when the device was originally programmed, then jumps to the power on initialization routine which would check that location and reset everything else to default values.

    I believe he wants a reset of the bootsector (or whatever its called) too...
    That would probably require flashing...
