"I never notice but I think mine only beeped on UEFI/BIOS 2.1, I have 2.4 now and no sound." Same with my P67, when I had BIOS 1.9 it beeped, with 1.C no beeps. I don't worry about it, I don't need beeps to figure out if or what problems are if any crop up.
And if you simply rely on "visuals", just wait until you power up and have no video.
A beep is needed to be able to tell the graphics isn't working?
advanced bios feature should contain the bios protection setting
