^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) Description
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) This SMBus only driver is known to work on motherboards with the above
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) named chipset combinations. The driver was developed without benefit of a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) proper datasheet from SiS. The SMBus registers are assumed compatible with
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) those of the SiS630, although they are located in a completely different
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) place. Thanks to Alexander Malysh <amalysh@web.de> for providing the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) SiS630 datasheet (and  driver).

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) The command ``lspci`` as root should produce something like these lines::

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) (kernel versions later than 2.4.18 may fill in the "Unknown"s)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 42) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 43) If you can't see it please look on quirk_sis_96x_smbus
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 44) (drivers/pci/quirks.c) (also if southbridge detection fails)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 45) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) I suspect that this driver could be made to work for the following SiS
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 47) chipsets as well: 635, and 635T. If anyone owns a board with those chips
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 48) AND is willing to risk crashing & burning an otherwise well-behaved kernel
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 49) in the name of progress... please contact me at <mhoffman@lightlink.com> or

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 57) * The driver does not support SMBus block reads/writes; I may add them if a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 58)   scenario is found where they're needed.
