19==================      =====================================================
20force = [1|0]           Forcibly enable the SIS630. DANGEROUS!
21                        This can be interesting for chipsets not named
22                        above to check if it works for you chipset,
23                        but DANGEROUS!
24
25high_clock = [1|0]      Forcibly set Host Master Clock to 56KHz (default,
26			what your BIOS use). DANGEROUS! This should be a bit
27			faster, but freeze some systems (i.e. my Laptop).
28			SIS630/730 chip only.

35This SMBus only driver is known to work on motherboards with the above
36named chipsets.

38If you see something like this::
39
40  00:00.0 Host bridge: Silicon Integrated Systems [SiS] 630 Host (rev 31)
41  00:01.0 ISA bridge: Silicon Integrated Systems [SiS] 85C503/5513
42
43or like this::
44
45  00:00.0 Host bridge: Silicon Integrated Systems [SiS] 730 Host (rev 02)
46  00:01.0 ISA bridge: Silicon Integrated Systems [SiS] 85C503/5513
47
48or like this::
49
50  00:00.0 Host bridge: Silicon Integrated Systems [SiS] 760/M760 Host (rev 02)
51  00:02.0 ISA bridge: Silicon Integrated Systems [SiS] SiS964 [MuTIOL Media IO]
52							LPC Controller (rev 36)
53
54in your ``lspci`` output , then this driver is for your chipset.
