Beep Codes
When POST finds an error and cannot display a message, the server's speaker emits a series of beeps to
indicate the error and places a value in I/O port 80h. During POST, if the video configuration fails or if an
external ROM module fails a checksum test, then the server beeps three times (one long beep, and two
short beeps).
The following table lists other fatal errors and their associated beep codes. Each code represents the
number of short beeps that are grouped together. Fatal errors (errors that lock up the server) are generally
the result of a failed main logic board or some other add-on component (SIMM, BIOS, server battery, etc.).
