1. What is the key initialization routine?Performs Power-On Self-Test (POST) to verify hardware integrity before loading the bootloader
2. What does BIOS do when you turn on your computer?BIOS wakes up right after the computer gets power, checks that all the main parts like the CPU, memory, and graphics are working, and then loads the bootloader that starts the operating system.
3. Why does my computer make beeps or show a message when something is wrong?During the Power‑On Self‑Test (POST), BIOS checks each piece of hardware. If it finds a problem, it tells you with beep codes or on‑screen messages so the computer can stop before it gets stuck.
