| 12 | Description | |
| 13 | ----------- | |
| 14 | ||
| 15 | SMSC SCH5636 Super I/O chips include an embedded microcontroller for | |
| 16 | hardware monitoring solutions, allowing motherboard manufacturers to create | |
| 17 | their own custom hwmon solution based upon the SCH5636. | |
| 18 | ||
| 19 | Currently the sch5636 driver only supports the Fujitsu Theseus SCH5636 based | |
| 20 | hwmon solution. The sch5636 driver runs a sanity check on loading to ensure | |
| 21 | it is dealing with a Fujitsu Theseus and not with another custom SCH5636 based | |
| 22 | hwmon solution. | |
| 23 | ||
| 24 | The Fujitsu Theseus can monitor up to 5 voltages, 8 fans and 16 | |
| 25 | temperatures. Note that the driver detects how many fan headers / | |
| 26 | temperature sensors are actually implemented on the motherboard, so you will | |
| 27 | likely see fewer temperature and fan inputs. | |

29 | The Fujitsu Theseus hwmon solution also contains an integrated watchdog. |
| 30 | This watchdog is fully supported by the sch5636 driver. | |

32 | An application note describing the Theseus' registers, as well as an |
| 33 | application note describing the protocol for communicating with the | |
| 34 | microcontroller is available upon request. Please mail me if you want a copy. |
