  14. Description

  15. -----------
    16. 

  16. 

  17. This SMBus only driver is known to work on motherboards with the above
    18. 

  18. named chipset combinations. The driver was developed without benefit of a
    19. 

  19. proper datasheet from SiS. The SMBus registers are assumed compatible with
    20. 

  20. those of the SiS630, although they are located in a completely different
    21. 

  21. place. Thanks to Alexander Malysh <amalysh@web.de> for providing the
    22. 

  22. SiS630 datasheet (and  driver).
    23. 

  23. 

  24. The command "lspci" as root should produce something like these lines:
    25. 

  25. 

  26. 00:00.0 Host bridge: Silicon Integrated Systems [SiS]: Unknown device 0645
    27. 

  27. 00:02.0 ISA bridge: Silicon Integrated Systems [SiS] 85C503/5513
    28. 

  28. 00:02.1 SMBus: Silicon Integrated Systems [SiS]: Unknown device 0016
    29. 

  29. 

  30. or perhaps this...
    31. 

  31. 

  32. 00:00.0 Host bridge: Silicon Integrated Systems [SiS]: Unknown device 0645
    33. 

  33. 00:02.0 ISA bridge: Silicon Integrated Systems [SiS]: Unknown device 0961
    34. 

  34. 00:02.1 SMBus: Silicon Integrated Systems [SiS]: Unknown device 0016
    35. 

  35. 

  36. (kernel versions later than 2.4.18 may fill in the "Unknown"s)
    37. 

  37. 

  38. If you cant see it please look on quirk_sis_96x_smbus
    39. 

  39. (drivers/pci/quirks.c) (also if southbridge detection fails)
    40. 

  40. 

  41. I suspect that this driver could be made to work for the following SiS
    42. 

  42. chipsets as well: 635, and 635T. If anyone owns a board with those chips
    43. 

  43. AND is willing to risk crashing & burning an otherwise well-behaved kernel
    44. 

  44. in the name of progress... please contact me at <mhoffman@lightlink.com> or
    45. 

  45. via the project's mailing list: <i2c@lm-sensors.org>.  Please send bug
    46. 

  46. reports and/or success stories as well.
    47.

  49. TO DOs
    50. 

  50. ------
    51. 

  51. 

  52. * The driver does not support SMBus block reads/writes; I may add them if a
    53. 

  53. scenario is found where they're needed.
    54.

  56. Thank You
