Beep Codes

Beep codes are used by the BIOS to indicate a serious or fatal error to the end user. Beep codes are used
when an error occurs before the system video has been initialized. Beep codes will be generated by the
system board speaker, commonly referred to as the PC speaker.
AMIBIOS displays the checkpoints in the bottom right corner of the screen during POST. This display method
is limited, since it only displays checkpoints that occur after the video card has been activated.
Not all computers using AMIBIOS enable this feature. In most cases, a checkpoint card is the best tool for
viewing AMIBIOS checkpoints.
