Changing CMOS battery, can reset upgraded MB Firmware? Tags: CPUs Battery Firmware CMOS Last response: February 11, 2012 8:04 PM in CPUs Share arcturuspica February 11, 2012 8:00:39 PM Hello, My cpu couldnt be seen until MB firmware was upgraded while having the old cpu installed. If CMOS battery dies and gets replaced, does MB retain the upgraded firmware or resets to the original one?
