The reset pin of AT91SAM7s remains inactive during power up.It has to be configured in the software to be active and that defeats the purpose of RESET. I don't know how can one design a chip like that!!!

I recall at one time PC manufacturers thought it needed a reset button on the front panel. Jaya

If you are running wondoze then it is still quite useful to have the reset button on the front panel...
