Mmm. The other question I had about the system reset controller is whether it's really purely hardware doing the "start secondary CPU", or is it just a funny way of asking the system firmware to start things, or is the stuff like the register for startup address just a place to leave information that the system firmware on the secondary CPU will read as part of its boot sequence? Is there a datasheet available for this? thanks -- PMM
