Datasheet: |

not publicly available, but seems to be similar to the |
|
AMD-8111 SMBus 2.0 adapter. |

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.
