Byte 0 of a response contains completion code for the command.
So, the examined data starts from byte 1. It's easy to make a mistake
here since specification counts response data from 1.
For the "Get Self Test Results" command Intelligent Platform Management
Interface Specification v2.0 rev 1.1 paragraph 20.4 defines response as:
+-----+---------------------------------------------------------------+
|byte | data field |
+-----+---------------------------------------------------------------+
| 1 | Completion Code |
| | |
| 2 | 55h = No error. All Self Tests Passed. |
| | 56h = Self Test function not implemented in this controller. |
| | 57h = Corrupted or inaccessible data or devices |
| | 58h = Fatal hardware error |
| | |
| 3 | For byte 2 = 55h, 56h, FFh: 00h |
| | For byte 2 = 58h, all other: Device-specific |
| | For byte 2 = 57h: self-test error bitfield. |
