Answer 2

Answer:

Upon startup, an NMI interrupt is asserted, and in kernel mode, it directs the processor to the handler address.

Power is supplied to the Motherboard and the CPU starts using the BIOS when you press the power button (Basic In-Out System). and the motherboard's ROM, which holds instructions. The OS that accesses the videocard is then started by the BIOS after it finds a legitimate OS on the disc or SSD. After the OS is loaded into RAM, pictures are then sent to the associated display.  Startup is completed by asking the user to continue with the necessary security, such as a password.
