27	Description
28	-----------
29	
30	i2c-nforce2 is a driver for the SMBuses included in the nVidia nForce2 MCP.
31	
32	If your 'lspci -v' listing shows something like the following,
33	
34	00:01.1 SMBus: nVidia Corporation: Unknown device 0064 (rev a2)
35	        Subsystem: Asustek Computer, Inc.: Unknown device 0c11
36	        Flags: 66Mhz, fast devsel, IRQ 5
37	        I/O ports at c000 [size=32]
38	        Capabilities: <available only to root>
39	
40	then this driver should support the SMBuses of your motherboard.
41

43	Notes
44	-----
45	
46	The SMBus adapter in the nForce2 chipset seems to be very similar to the
47	SMBus 2.0 adapter in the AMD-8111 south bridge. However, I could only get
48	the driver to work with direct I/O access, which is different to the EC
49	interface of the AMD-8111. Tested on Asus A7N8X. The ACPI DSDT table of the
50	Asus A7N8X lists two SMBuses, both of which are supported by this driver.
