The BIOS is in the RAM. You select the changes that you want for the BIOS boot. You press F10 then enter. The computer flashes the changes to the BIOS memory. And then it shuts down—clearing the RAM. The BIOS memory then boots BIOS in RAM. Since the BIOS memory has been flashed, it follows the new instructions when it boots.
