7.4 BIOS Error Beep (POST) Codes

During the POST (Power-On Self-Test) routines, which are performed each time the system
is powered on, errors may occur.
Non-fatal errors are those which, in most cases, allow the system to continue the boot-up
process. The error messages normally appear on the screen.
Fatal errors are those which will not allow the system to continue the boot-up procedure. 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 table
below lists some common errors and their corresponding beep codes encountered by users.
Beep Code Error
1 short
5 short, 1 long
5 long, 2 short
1 long continuous

Additional BIOS POST Codes

The AMI BIOS supplies additional checkpoint codes, which are documented online at
www.supermicro.com/support/manuals/
When BIOS performs the Power On Self Test, it writes checkpoint codes to I/O port 0080h.
If the computer cannot complete the boot process, a diagnostic card can be attached to the
computer to read I/O port 0080h (Supermicro p/n AOC-LPC80-20).
For information on AMI updates, please refer to http://www.ami.com/products/.
