| 14 | ----------- |
| 15 | |
| 16 | SMSC SCH5627 Super I/O chips include complete hardware monitoring |
| 17 | capabilities. They can monitor up to 5 voltages, 4 fans and 8 temperatures. |

| 20 | watchdog. In order for this watchdog to function some motherboard specific |
| 21 | initialization most be done by the BIOS, so if the watchdog is not enabled |
| 22 | by the BIOS the sch5627 driver will not register a watchdog device. |

| 25 | through an embedded microcontroller. An application note describing the |
| 26 | protocol for communicating with the microcontroller is available upon |
| 27 | request. Please mail me if you want a copy. |
