error Messages

Your computer’s built-in memory (ROM) contains a series of

diagnostic programs, called power-on diagnostics. These

programs check internal devices such as ROM, RAM, the timer,

the keyboard controller, and the hard disk drive every time you

turn on the computer or press the reset button. The RAM test

program displays a count of the memory currently installed in

your system.

If the computer finds an error, it reports one of the following

types of error messages:

Power-on diagnostic and boot error messages

Error tone codes for fatal errors (conditions that lock up the

system)

Error tone codes for non-fatal errors (conditions that do not

lock up the system).

Be sure to write down the error message or tone code pattern

and give the information to your dealer or servicer when you

report a problem. These error messages are described below.

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.
