Appendix A Bios Post Error Beep Codes; Bios Post Error Beep Codes - Supermicro X10DSC+ User Manual

During the POST (Power-On Self-Test) routines, which are performed upon each
system boot, errors may occur.
Non-fatal errors are those which, in most cases, allow the system to continue to
boot. These error messages normally appear on the screen.
Fatal errors will not allow the system to continue with bootup. If a fatal error occurs,
you should consult with your system manufacturer for possible repairs.
These fatal errors are usually communicated through a series of audible beeps.
The numbers on the fatal error list correspond to the number of beeps for the cor-
responding error.
