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

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