| 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 cant 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 project's mailing list: <sensors@stimpy.netroedge.com>. 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 |
