When we switch on the power button, CPU pins are reset and registers are set to their predefined values.
The first step in booting is the reset vector. At this time, the RAM contains garbage values and the data stored at any memory location is because the chipset has located those memory spaces.Memory map maps the location to delete memory containing values or any instructions.Instruction stored at reset vector location jumps to the location of BIOS (Basic Input Output system).
BIOS run POST (Power-On Self Test) and other necessary checks such as:
- It Initializes the hardware devices by allowing them to run their individual BIOS
- Searching and reading the Master Boot Record.
- Help in copying the boot sector code to RAM. It also helps in switching the control.
BIOS jumps to MBR(Master Boot Record).
Primary Bootloader runs from MBR and jumps to Secondary Bootloader.
Secondary Bootloaders loads OS.
