Port 80h POST Codes
When there is an FRB3 failure, the event message sent from the CPU Status sensor with sensor
type code 07 provides the last Port 80 code byte written by the BIOS. This information is contained
in Data Byte 3 of the event message.
Example:
To decode Port 80 data from SEL event when a board is booted without memory, refer to the
following method.
SEL EVENT - ID:0DD8(Tue Jan 25 18:45:20 2005) Gen:8E Type:07 No:50 Dir:6F D1:64 D2:6F
D3:E1
The values shown in bold above convey the following information:
•
The sensor type is 07. This refers to the processor.
•
Event data 1, bit 0-3 is 4. This refers to an FRB3/processor startup or initialization failure (the
CPU did not start).
•
Event data 3 is E1. This refers to the last Port 80h POST codes before the board hangs.
for descriptions of the Port 80h POST codes.
Note:
At any time when a board hangs, you may also use an OEM IPMI command to query the Port 80
POST codes. For the command syntax, refer to
Section 3.7.7, “Get Port80 Data” on page 52
