^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) i2c-nforce2 is a driver for the SMBuses included in the nVidia nForce2 MCP.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) If your ``lspci -v`` listing shows something like the following::

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 43) then this driver should support the SMBuses of your motherboard.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 48)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 49) The SMBus adapter in the nForce2 chipset seems to be very similar to the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 50) SMBus 2.0 adapter in the AMD-8111 south bridge. However, I could only get
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 51) the driver to work with direct I/O access, which is different to the EC
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 52) interface of the AMD-8111. Tested on Asus A7N8X. The ACPI DSDT table of the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 53) Asus A7N8X lists two SMBuses, both of which are supported by this driver.
