Troubleshooting
A PCI expansion card (for example, a RAID controller) can also issue audible errors by itself, usually consisting of one long tone followed by a series of short tones. For more information on the beep codes issued, check the documentation for that device.
Several POST routines issue a POST terminal error and shut down the system when they fail. Before shutting down the system, the terminal error handler sounds a beep code (one long tone and a series of short tones) that identifies the test point error. If POST completes normally, the BIOS issues one short beep before passing control to the operating system.
