POST obtains the list of hardware that is supposed to be in the computer from the settings stored in CMOS. This means that the BIOS already knows what hardware is supposed to be present in the system, and can then test each component accordingly. This is a more efficient method than relying on an installed hardware folder or having a comprehensive list of all possible hardware components.
