POST checkpoint codes

POST 80 codes

his section lists the POST checkpoint codes that the system BIOS may send to I/O port 80h 
during POST. They are presented in an alphabetically ascending order and are not 
necessarily in order of execution.

If an error occurs at any of the listed checkpoints, the system attempts to generate beeps 
to indicate where the error occurred. To hear the beeps, connect a speaker (not included) 
to the speaker pin on the front panel I/O header. Beep codes are derived from the 
checkpoint code in the following way:

1. The 8-bit hexadecimal checkpoint code is converted to binary, then the binary number 

is divided into four 2-bit groups. For example:

Checkpoint code 20h = 00100000 = 00-10-00-00

2. Each 2-bit group is converted to a one-based number, and 1 is added to indicate the 

number of beeps:

3. 00 10 00 00 = 1-3-1-1 beeps

Note: 

Only standard Phoenix TrustedCore BIOS POST 80 codes are listed in the tables 

below. If you encounter other POST 80 codes, contact RadiSys for further assistance.
