A-1 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 numbers
on the fatal error list (on the following page) correspond to the number of beeps for the
corresponding error. All errors listed, with the exception of Beep Code 8, are fatal errors.
Beep Code Error Message
1 short Refresh
5 short, 1 long Memory error
5 long, 2 short Display memory read/write error
1 long continuous System OH
A-2 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/.
