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 (described in the next section).
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. Check the
appropriate section(s) in this appendix for other solutions.
