The POST (Power On Self Test).
BIOS is activated by powering on the CPU
The first step in the boot process is the Power-On Self-Test (POST). When the computer is powered on, the BIOS or UEFI firmware initializes the hardware components and checks for any errors. If the POST is successful, the system then proceeds to locate and load the boot loader from the designated boot device.
