POST and Boot Messages
The POST displays messages to alert to errors in hardware, software and firmware or to provide operating
information about the computer.
Each time the POST displays a message on the screen, the computer's speaker beeps twice. If an error
occurs before the monitor is initialised, specific beep codes sound to alert to a problem. The following
table lists a general grouping of system messages. In addition, each message is accompanied by text
describing the message and in most cases, a recommended solution to the problem.
NOTE Italics indicate variable parts of a message such as memory addresses,
hexadecimal valuesand so on. These messages can differ at each occurrence.
