Description¶

SMSC SCH5627 Super I/O chips include complete hardware monitoringcapabilities. They can monitor up to 5 voltages, 4 fans and 8 temperatures.

The SMSC SCH5627 hardware monitoring part also contains an integratedwatchdog. In order for this watchdog to function some motherboard specificinitialization most be done by the BIOS, so if the watchdog is not enabledby the BIOS the sch5627 driver will not register a watchdog device.

The hardware monitoring part of the SMSC SCH5627 is accessed by talkingthrough an embedded microcontroller. An application note describing theprotocol for communicating with the microcontroller is available uponrequest. Please mail me if you want a copy.
