15 Datasheet: not publicly available, but seems to be similar to the
16 AMD-8111 SMBus 2.0 adapter.

26 i2c-nforce2 is a driver for the SMBuses included in the nVidia nForce2 MCP.
28 If your 'lspci -v' listing shows something like the following,
30 00:01.1 SMBus: nVidia Corporation: Unknown device 0064 (rev a2)
31 Subsystem: Asustek Computer, Inc.: Unknown device 0c11
32 Flags: 66Mhz, fast devsel, IRQ 5
33 I/O ports at c000 [size=32]
34 Capabilities: <available only to root>
36 then this driver should support the SMBuses of your motherboard.
42 The SMBus adapter in the nForce2 chipset seems to be very similar to the
43 SMBus 2.0 adapter in the AMD-8111 south bridge. However, I could only get
44 the driver to work with direct I/O access, which is different to the EC
45 interface of the AMD-8111. Tested on Asus A7N8X. The ACPI DSDT table of the
46 Asus A7N8X lists two SMBuses, both of which are supported by this driver.
