Power-on Diagnostic and Boot Errors

When the power-on diagnostic tests detect an error, the
computer displays a message on the screen (as described
below) and the speaker beeps twice. If the error occurs before
the computer initializes the video display, the speaker sounds
a series of beeps.
Each error is identified by a message number and a
countdown number which the computer uses as it executes
the test associated with the error.
The table below lists the power-on diagnostic and boot error
messages, and some basic solutions to the problems.
