BIOS Beep Codes and Messages
Each time the system is powered “On” or reset, the BIOS executes a Power-On
Self Test (POST). This series of tests verifies that the unit is able to
perform basic functions related to the system board. It also does a system
configuration verification where it compares the defined configuration with
the actual installed hardware. Error messages and system beeps from the POST
will alert you to any system errors that were found.
If an error is detected during this test, you will see a displayed error message.
If the error occurs before the display is initialized, the system will issue a beep
or a series of beeps. If the error is fatal (non-correctable), the system halts after
reporting the fatal error. If it is a non-fatal (correctable) error, the process
continues after reporting the error.
If the BIOS detects any problems, they are communicated through error
messages. Errors are reported in one of two ways:
• If the error occurs before the display device initializes, a series of beeps
will sound. Beep codes indicate that a fatal error has occurred. A beep code
is an error message consisting of speaker tones arranged in distinctive
patterns.
• If the error occurs after the display device initializes, the error message is
displayed as text. With some displayed error messages a prompt to press
<F1> may appear.
Should your system issue any error messages or beep codes before or during
POST testing, look up the error message(s) and beep codes listed on the next
few pages to determine whether you should try to fix the problem yourself or
contact Kontron technical support for assistance.
