+Kernel driver i2c-sis630
+========================

+Supported adapters:
+  * Silicon Integrated Systems Corp (SiS)
+	630 chipset (Datasheet: available at http://www.sfr-fresh.com/linux)
+	730 chipset
+	964 chipset
+  * Possible other SiS chipsets ?

+Module Parameters

+==================      =====================================================
+force = [1|0]           Forcibly enable the SIS630. DANGEROUS!
+                        This can be interesting for chipsets not named
+                        above to check if it works for you chipset,
+                        but DANGEROUS!
+
+high_clock = [1|0]      Forcibly set Host Master Clock to 56KHz (default,
+			what your BIOS use). DANGEROUS! This should be a bit
+			faster, but freeze some systems (i.e. my Laptop).
+			SIS630/730 chip only.

+Description
+-----------
+
+This SMBus only driver is known to work on motherboards with the above
+named chipsets.
+
+If you see something like this::
+
+  00:00.0 Host bridge: Silicon Integrated Systems [SiS] 630 Host (rev 31)
+  00:01.0 ISA bridge: Silicon Integrated Systems [SiS] 85C503/5513
+
+or like this::
+
+  00:00.0 Host bridge: Silicon Integrated Systems [SiS] 730 Host (rev 02)
+  00:01.0 ISA bridge: Silicon Integrated Systems [SiS] 85C503/5513
+
+or like this::
+
+  00:00.0 Host bridge: Silicon Integrated Systems [SiS] 760/M760 Host (rev 02)
+  00:02.0 ISA bridge: Silicon Integrated Systems [SiS] SiS964 [MuTIOL Media IO]
+							LPC Controller (rev 36)
+
+in your ``lspci`` output , then this driver is for your chipset.
