I segnali acustici che vengono emessi dal computer al suo avvio hanno un significato particolare, infatti in base alla loro sequenza si riconoscono diversi tipi di errore.
Di seguito trovate l’elenco delle principali segnalazioni acustiche suddivise per produttore di BIOS, se il vostro produttore di BIOS non è presente nell’elenco fare eventualmente riferimento allo standard IBM
