SM Bus not working after installing nForce drivers

Since XP is dead, I am setting up a "new" old system...

I have tried the nForce Professional 2200 installer from Tyan. The SM Bus controller ended up under Other in Device Manager with a Yellow exclamation point.

So I downloaded the latest drivers from nVidia site. The SM Bus moved to System Devices in Device Manager, but still has a yellow exclamation point.

The SM Bus driver version is 4.6.4.0 . When I try to update the driver, I get this message: "Windows has determined that the driver software for your device is up to date."

Both of the Tyan and nVidia packages are labeled for Vista64, but I am running Windows 7 64. There is no driver specifically labeled for Windows 7 that I can find.

Motherboard: Tyan S2877
2 Opteron CPUs installed
Memory: 5GB ECC Registered
Windows 7 64-bit (SP2 & recommended & important updates installed)

Please help!

    It's the Chipset driver you need for the SMBUS

    If the Vista driver doesn't work on Windows 7, you can't use Windows 7 with that Tyan board model.
    I can clearly see on the Tyan download page that Win7 isn't supported.

    The SM Bus is Intel's adaptation of the I2C interface for motherboard peripheral configuration. It's not a complicated interface and its operation is primarily firmware driven. OS drivers which replace the firmware drivers are provided as a part of chipset installation packages but they are not strictly necessary.

    NForce chipsets are obsolete trash. Support under Linux will not be any better
  4. To LambdaFox - you are supposed to check your motherboard maker's website to see what drivers it has before changing the OS, not after.
  5. I did, and I wanted to try the Vista 64 drivers and see if I could get them to work. I also thought since my board and chipset had been around for such a long time there might be a workaround not "officially" posted on Tyan's website because the board is "legacy"...

    There are official 64bit drivers for in the linux kernel. I am currently setting up lubuntu...
