AMI BIOS beep codes
Below are the AMI BIOS Beep codes that can occur. However, because of the wide variety of different computer manufacturers with this BIOS, the beep codes may vary.
| Beep Code | Descriptions |
| 1 short | DRAM refresh failure |
| 2 short | Parity circuit failure |

Below are Award BIOS Beep codes that can occur. However, because of the wide variety of different computer manufacturers with this BIOS, the beep codes may vary.
| Beep Code | Description |
| 1 long, 2 short | Indicates a video error has occurred and the BIOS cannot initialize the video screen to display any additional information |
| Any other beep(s) | RAM problem. |
If any other correctable hardware issues, the BIOS will display a message.
Below are general IBM BIOS Beep codes that can occur. However, because of the wide variety of models shipping with this BIOS, the beep codes may vary.
