POST beep code descriptions
POST emits one beep to signal successful completion. If POST detects a problem
during startup, other beep codes might occur. You can use the following beep code
descriptions to help identify and resolve problems that are detected during startup.
Note: Refer to the "Solving Problems" section in the User’s Reference on the IBM
Documentation CD for more detailed information about the POST beep codes.
