Table 3-4: POST Error Messages
Operating system not found
Terminal POST Errors
There are several POST routines that issue a POST terminal error and shut down the system
if they fail. Before shutting down the system, the terminal-error handler issues a beep code
signifying the test point error, writes the error to port 80h, attempts to initialize the video, and
writes the error in the upper left corner of the screen (using both mono and color adapters).
POST Beep Codes
The POST routines cannot display messages when an error occurs if any of the following are
present:
•
The error occurs before the video display is initialized.
•
The video configuration fails, either there's no graphics card installed or the one installed
is faulty.
•
An external ROM module does not properly checksum to zero.
•
The system memory cannot be initialized.
During these instances the server unit emits a buzzing sound followed by a series of audible
beeps. An external ROM module (e.g. VGA) can also issue audible errors, usually consisting
of one long tone followed by a series of short tones. If you get a blank screen on boot, but
hear beeps, count the beeps and refer to the following table for their corresponding meaning.
If you miss the beep code:
1. Turn off the server by pressing the power button for five seconds or more.
2. Restart the server by pressing the power button.
3. Listen for the signal again.
