What Really Happens When You Turn the Computer On?
What Really Happens When You Turn the
Computer On?
When you press the power button, the following occurs:
1 The computer's BIOS (Basic Input/Output System) loads
a bootstrap program.
This program, named from the expression "pull yourself up by
your bootstraps," checks and displays the amount of memory
in the system before proceeding.
2 The bootstrap program attempts to load Windows 95.
It looks first for a diskette in the diskette drive and then at the
hard disk. If a diskette without the necessary startup files is in
the drive, the bootstrap program displays an error message.
3 As Windows 95 loads, it configures the system.
4 Windows 95 loads the desktop.
