18-----------
19
20SMSC SCH5627 Super I/O chips include complete hardware monitoring
21capabilities. They can monitor up to 5 voltages, 4 fans and 8 temperatures.
22
23The SMSC SCH5627 hardware monitoring part also contains an integrated
24watchdog. In order for this watchdog to function some motherboard specific
25initialization most be done by the BIOS, so if the watchdog is not enabled
26by the BIOS the sch5627 driver will not register a watchdog device.
27
28The hardware monitoring part of the SMSC SCH5627 is accessed by talking
29through an embedded microcontroller. An application note describing the
30protocol for communicating with the microcontroller is available upon
31request. Please mail me if you want a copy.
