- As soon as you turn the computer on
- the BIOS chips come to life. BIOS
- stands for Basic Input Output
- System. The computer has one or
- more of these ROM (Read Only
- Memory) chips. The BIOS is the
- first step in telling the computer
- who it is. The Central Processing
- Unit (CPU chip) is the main
- thinking part of the computer, but
- so far, it has no thoughts to think
- about. The BIOS hooks it up to
- other parts, places where thoughts
- can be stored. The BIOS tells it
- how to talk with the disk drives,
- the RAM (Random Access Memory), the
- keyboard and the monitor.

- The computer wakes up and
- starts looking around to see
- what parts it has. It learns
- how to read input from the
- keyboard and how to send a
- picture to the monitor. Then
- it checks to see how many and
- what kind of disk drives it
- has. You see each drive light
- momentarily flash on.
