Bios Post Beep Codes; Table 11. Post Error Beep Codes - Intel S3420GP Manual

BIOS POST Beep Codes

The following table lists the POST error beep codes. Prior to system video initialization,
the BIOS uses these beep codes to inform users of error conditions. The beep code is
followed by a user-visible code on POST Progress LEDs.
Number of Beeps
3
In the case of POST error(s) that are listed as Major, the BIOS enters the error manager
and waits for the user to press an appropriate key before booting the operating system or
entering the BIOS Setup.
The user can override this option by setting the POST Error Pause option as disabled on
the BIOS setup Main screen. If this option is disabled, the system boots the operating
system without user intervention. The default is disabled.
