BIOS POST Beep Codes
The following table lists 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.
Table 5. POST Error Beep Codes
In 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.
