- 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.
