11 AMI BIOS Beep Codes
It is normal for Kontron AMI UEFI BIOS to generate some beeps after POST has passed successfully:
The first beep indicates that POST has successfully passed.
Then a number of beeps indicate the number of attached USB devices.
And finally a special long beep indicates that AMI boot is completed.
Note: The long beep starting as a normal beep but is changing to higher frequency.
If POST has found a problem, then the normal behaviour (described above) is changed:

Troubleshooting POST BIOS Beep Codes:
Number of
Beeps
Troubleshooting Action
1, 2 or 3 Reset the memory, or replace with known good modules.
4-7, 9-11 Fatal error indicating a serious problem with the system. Consult your system
manufacturer. Before declaring the motherboard beyond “all hope”, eliminate the
possibility of interference due to a malfunctioning add-in card. Remove all expansion
cards, except the video adapter.
• If beep codes are generated when all other expansion cards are absent, consult your
system manufacturer’s technical support.
• If beep codes are not generated when all other expansion cards are absent, one of the
add-in cards is causing the malfunction. Insert the cards back into the system one at a
time until the problem happens again. This will reveal the malfunctioning card.
8 If the system video adapter is an add-in card, replace or reset the video adapter. If the
video adapter is an integrated part of the system board, the board may be faulty.
