POST Error Beep Codes
The following table lists POST error beep codes. Prior to system Video initialization,
BIOS uses these beep codes to inform users on error conditions. The beep code is
followed by a user
visible code on the diagnostic LEDs.
POST Error Pause Option
For POST error(s) that are listed as Pause, the BIOS enters the error manager and waits
for the user to press an appropriate key before booting the operating system or entering
BIOS Setup.
The user can override this option by setting POST Error Pause to disabled in the BIOS
Setup utility Main menu page. If POST Error Pause is set to disabled, the system will
boot the operating system without user-intervention. The default value is set to enabled.
8600 Primary and secondary BIOS IDs do not match Pause
8601 Override jumper is set to force boot from lower alternate
BIOS bank of flash ROM Pause
8602 WatchDog timer expired (secondary BIOS may be bad!) Pause
8603 Secondary BIOS checksum fail Pause
