Even though I don't consider myself a newbie at this point, I am posting this in the Newbie Forum because it is really a newbie question. Here goes: Firmware. Exactly what IS the firmware on my P4? I have no idea what it is. Upgrade. All I hear about is upgrading my firmware. Setting aside the rather obvious double meaning here (especially for a man my age), is there a way to tell if it is necessary for me to upgrade my firmware and, if so, how do I do that? I just got my P4. I would assume no upgrade is necessary, but want to make sure. Any thoughts would be appreciated.
