+Hardware Interfaces
+-------------------
+
+All the chips suported by this driver are LPC Super-I/O chips, accessed
+through the LPC bus (ISA-like I/O ports). The IT8712F additionally has an
+SMBus interface to the hardware monitoring functions. This driver no
+longer supports this interface though, as it is slower and less reliable
+than the ISA access, and was only available on a small number of
+motherboard models.
