As soon as you turn on the computer
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.
