Most computers have a keystroke (usually esc, del, or F12) that will interrupt the boot sequence when you start your computer. In the past, this would be when the white text flies across the screen displaying memory available, hard disk sizes, etc. This will get you into the BIOS for "cmos setup".

CMOS is a type of memory that does not lose its data on power loss. In earlier computers, this is where the boot up configuration was stored; hence the phrase, "setup cmos"
