| 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. |
