+  * Silicon Integrated Systems Corp (SiS)
+    Any combination of these host bridges:
+	645, 645DX (aka 646), 648, 650, 651, 655, 735, 745, 746

+Description
+-----------
+
+This SMBus only driver is known to work on motherboards with the above
+named chipset combinations. The driver was developed without benefit of a
+proper datasheet from SiS. The SMBus registers are assumed compatible with
+those of the SiS630, although they are located in a completely different
+place. Thanks to Alexander Malysh <amalysh@web.de> for providing the
+SiS630 datasheet (and  driver).
+
+The command "lspci" as root should produce something like these lines:
+
+00:00.0 Host bridge: Silicon Integrated Systems [SiS]: Unknown device 0645
+00:02.0 ISA bridge: Silicon Integrated Systems [SiS] 85C503/5513
+00:02.1 SMBus: Silicon Integrated Systems [SiS]: Unknown device 0016
+
+or perhaps this...
+
+00:00.0 Host bridge: Silicon Integrated Systems [SiS]: Unknown device 0645
+00:02.0 ISA bridge: Silicon Integrated Systems [SiS]: Unknown device 0961
+00:02.1 SMBus: Silicon Integrated Systems [SiS]: Unknown device 0016
+
+(kernel versions later than 2.4.18 may fill in the "Unknown"s)
+
+If you can't see it please look on quirk_sis_96x_smbus
+(drivers/pci/quirks.c) (also if southbridge detection fails)
+
+I suspect that this driver could be made to work for the following SiS
+chipsets as well: 635, and 635T. If anyone owns a board with those chips
+AND is willing to risk crashing & burning an otherwise well-behaved kernel
+in the name of progress... please contact me at <mhoffman@lightlink.com> or
+via the linux-i2c mailing list: <linux-i2c@vger.kernel.org>.  Please send bug
+reports and/or success stories as well.
+
+
+TO DOs
+------
+
+* The driver does not support SMBus block reads/writes; I may add them if a
+scenario is found where they're needed.

+Thank You
