thats what i always say,, if it aint broke,,, dont fix it,, wish i practiced what i preach
yes i have a rescue disc, but i dont think that would reset any bios updates to original factory settings, i think it proberbly only reset the windows system itself,
i know i should have left alone

, i dont know enough on anything to do with bios, i only did it because it came from toshibas updates service
