Critical Error BEEP Codes
Embedded BIOS tests much of the hardware early in POST before
messages can be displayed on the screen. When system failures are
encountered at these early stages, POST uses beep codes (a sequence of
tones on the speaker) to identify the source of the error.
The following is a comprehensive list of POST beep codes for the
system BIOS. BIOS extensions, such as VGA ROMs and SCSI adapter
ROMs, may use their own beep codes, including short/long sequences,
or possibly beep codes that sound like the ones below. When
diagnosing a system failure, remove these adapters if possible before
making a final determination of the actual POST test that failed.
