Boot Process

Step 10 - Bootstrap Loader

Loads operating system from the bootstrap loader.

Step 8 - Memory

The POST writes and reads from the systems RAM

Step 6 - System Bus

The BIOS will have CPU send signals over the system bus to make sure all basic components are working.

Step 4 - BIOS and CMOS

BIOS and CMOS communicate to make sure everything is there where it is supposed to be.

BIOS talks to CMOS

Step 2 - The CPU wakes up

BIOS doesn't care about the make and model.

CPU is going to activate the BIOS.

BIOS is a very basic understanding how computer hardware is supposed to work.

Power supply then wakes up the CPU.

The CPU is brought into the boot process.

Step 9 - The Handoff

POST hands off to a process called the bootstrap loader

Step 7 - Video

This is the first time in the boot process anything is displayed on the monitor.

POST launches video display

It uses very basic video settings

Step 5 - Loading Drivers

BIOS loads very basic drivers for devices attached to the computer into system memory.

Step 3 - POST

BIOS starts the Power On Self Test (POST)

Step 1 - Power Good

The power supply is going to taste the power and make sure everything is OK.

You turn the computer on.
