14Description
15-----------
16
17This SMBus only driver is known to work on motherboards with the above
18named chipset combinations. The driver was developed without benefit of a
19proper datasheet from SiS. The SMBus registers are assumed compatible with
20those of the SiS630, although they are located in a completely different
21place. Thanks to Alexander Malysh <amalysh@web.de> for providing the
22SiS630 datasheet (and  driver).

24The command "lspci" as root should produce something like these lines:
25
2600:00.0 Host bridge: Silicon Integrated Systems [SiS]: Unknown device 0645
2700:02.0 ISA bridge: Silicon Integrated Systems [SiS] 85C503/5513
2800:02.1 SMBus: Silicon Integrated Systems [SiS]: Unknown device 0016
29
30or perhaps this...
31
3200:00.0 Host bridge: Silicon Integrated Systems [SiS]: Unknown device 0645 
3300:02.0 ISA bridge: Silicon Integrated Systems [SiS]: Unknown device 0961
3400:02.1 SMBus: Silicon Integrated Systems [SiS]: Unknown device 0016
35
36(kernel versions later than 2.4.18 may fill in the "Unknown"s)
37
38If you cant see it please look on quirk_sis_96x_smbus
39(drivers/pci/quirks.c) (also if southbridge detection fails)
40
41I suspect that this driver could be made to work for the following SiS
42chipsets as well: 635, and 635T. If anyone owns a board with those chips
43AND is willing to risk crashing & burning an otherwise well-behaved kernel
44in the name of progress... please contact me at <mhoffman@lightlink.com> or
45via the project's mailing list: <sensors@stimpy.netroedge.com>.  Please
46send bug reports and/or success stories as well.

52* The driver does not support SMBus block reads/writes; I may add them if a
53scenario is found where they're needed.
