| POST code displays | |
| During power-up self test (POST), most PC system BIOSes write status codes to I/O port 80h or 84h. A POST code display shows the last value written to this port as a hexadecimal number. Use this code to diagnose problems. BIOS Central has a very complete collection of POST code tables. |
