9.2 System Firmware Progress (Formerly Post Error)
The BIOS logs any POST errors to the SEL. The 2-byte POST code gets logged in the ED2 and ED3 bytes in the SEL entry. This event will be
logged every time a POST error is displayed. Even though this event indicates an error, it may not be a fatal error. If this is a serious error,
there will typically also be a corresponding SEL entry logged for whatever was the cause of the error – this event may contain more information
about what happened than the POST error event.
