AMIBIOS is American Megatrend's branded BIOS software. American Megatrends, sometimes referred to as AMI, is one of the top BIOS software makers in the world. Many motherboard manufacturers have integrated AMIBIOS into their motherboards and, when trouble starts, will sound the AMIBIOS beep codes.

Some motherboards have custom BIOS software based on AMIBIOS so, depending on the motherboard, the beep codes from the custom BIOS may be exactly the same as the AMIBIOS beep codes or they may vary slightly. Most motherboard manufacturers will list the specific beep codes in their product manuals so reference yours when in doubt.

Note: AMIBIOS beep codes are short, sound in quick succession and usually sound almost immediately after powering on the PC.

Below are the technical causes of each AMIBIOS beep code followed by a short series of steps to resolve the cause of the issue.

  • Insert the expansion cards back into the system one by one, powering on after each insert, until the beep codes begin again.
