when booting my 5950x into windows, i never see the bios screen. It's about 50/50 if i see the nvidia bios screen, then i see the motherboard logo with the windows spinner under it. there's about 500ms where i can push F2 or whatever between when the logo shows up and the spinner shows up that i can "enter bios" - but that itself takes about 5 seconds to become fully realized on the screen. I know of what you speak, but i don't know if this is universally true.
