18 | The BMC Teutates is the Eleventh generation of Superior System |
| 19 | monitoring and thermal management solution. It is builds on the basic | |
| 20 | functionality of the BMC Theseus and contains several new features and | |
| 21 | enhancements. It can monitor up to 4 voltages, 16 temperatures and | |
| 22 | 8 fans. It also contains an integrated watchdog which is currently | |
| 23 | implemented in this driver. | |

25 | The ``pwmX_auto_channels_temp`` attributes show which temperature sensor |
| 26 | is currently driving which fan channel. This value might dynamically change | |
| 27 | during runtime depending on the temperature sensor selected by | |
| 28 | the fan control circuit. | |

30 | The 4 voltages require a board-specific multiplier, since the BMC can |
| 31 | only measure voltages up to 3.3V and thus relies on voltage dividers. | |
| 32 | Consult your motherboard manual for details. | |

| 7576750f | 34 | To clear a temperature or fan alarm, execute the following command with the |
| b04f2f7d MCC |
35 | correct path to the alarm file:: |
| 36 | ||
| 7576750f TC |
37 | echo 0 >XXXX_alarm |
