| 17 | Description | |
| 18 | ----------- | |
| 19 | ||
| 20 | SMSC SCH5627 Super I/O chips include complete hardware monitoring | |
| 21 | capabilities. They can monitor up to 5 voltages, 4 fans and 8 temperatures. | |

23 | The SMSC SCH5627 hardware monitoring part also contains an integrated |
| 24 | watchdog. In order for this watchdog to function some motherboard specific | |
| 25 | initialization most be done by the BIOS, so if the watchdog is not enabled | |
| 26 | by the BIOS the sch5627 driver will not register a watchdog device. | |

28 | The hardware monitoring part of the SMSC SCH5627 is accessed by talking |
| 29 | through an embedded microcontroller. An application note describing the | |
| 30 | protocol for communicating with the microcontroller is available upon | |
| 31 | request. Please mail me if you want a copy. |
