For anyone who will find this post in the future, the Device Manager indicates that the 'Device Instance Path' is

pci co-processor pci\ven_10de&dev_0aa3&subsys_cb7910de&rev_b1\3&21436425&0&1d

Searching for that online, it appears that this is the nVidia MCP79 Co processor System.

This driver did not install with version 306.37 that came with the BootCamp drivers. I downloaded the current version from nVidia of 334.89 and that didn't work either. I searched online and found a driver for an Alienware 17x that uses the same co processor and ran the installer which extracted the files for the nVidia chipset v. 15.57 for 64-bit Windows 7 and Vista to c:\dell\drivers\R273039 and pointed the Device Manager to this folder and it was able to successfully install the driver software for the Management Controller (drivers are listed under the SMU folder for the "PCI\VEN_10DE&DEV_0AA3" device).

NVIDIA nForce System Management Controller

I then proceeded to use Double Driver to backup the drivers in use by the system so that if I install Windows 8 on future systems I can use this rather than the round-about way of getting the driver installed on the system.

Could you give me a link to where you got the driver from?

It's a mistake to install 8.1 on Bootcamp now.

As you can read on Bootcamp support page (http://support.apple.com/kb/HT5639) : "Windows 8.1 is not supported with Boot Camp 5."

So it's not a surprise if your Windows is not fully OK...

It's careful to wait apropriate drivers on a new Bootcamp version.

Have you tried installing the latest available drivers for your platform? They are available at Boot Camp Support Software 4.0.4033. There is no official W8.1 support, so you can try the nVidia drivers as mentioned in the OP.

You should use Win7_64 (and 64-bit drivers) for Windows.

Bootcamp automatically installs the drivers when Windows is installed the first time. If you upgrade Windows, you will need appropriate drivers for your hardware from Bootcamp Downloads page. Please verify System Requirements first.

Apple - Support - Downloads

Do you want to consider getting a retail CD of OS X version that you need...

A littles help from you will be a pleasure to me.

Hi Loner T

If I go into boot camp Support Software 4.0.4033 and then open up to bootcamp then drivers then NVidia which one do I install to correctly get the drivers for Coprocessor and Sm Bus Controller ? etc....... which file folder? NVidiaChipset32 or NVidiaChipset64 or Win7_32 or Win7_64. thanks

As I have a White MacBook 13 inch os x lion 10.7.5 mid 2010 and which I have but windows 8 on. Thanks

I already updated bootcamp to 5.1 but if I just do the drivers for NVidia from the bootcamp 4.0.4033 the windows64, then this should put the drivers in for Coprocessor and Sm Bus Controller? as the 5.1 don't

Hi,

I have now tried all the updates from 4 to 5 etc in bootcamp and none of them work in fixing the drivers for Coprocessor and SM Bus Controller? they still not have the drivers, what are they for anyway? I have MacBook 13inch mid 2010 os x lion 10.7.5 I have update the lion to Yosemite and I have bootcamp the MacBook for windows 8 pro now updated to 8.1 and the only thing that doesn't have drivers from any of the bootcamps is Coprocessor and SM Bus Controller? ta

Hi, I managed to install the Drivers for the Coprocessor and SM Bus Controller by extracting the bootcamp4 file called bootcamp to the desktop then I went into the device manager clicked on the Coprocessor and then tell it to look at the bootcamp on the desktop and then it put the files in and I also did it for the SM Bus Controller . all good now thanks

Thanks for your answer!

As you described, I downloaded the dell R273039 soft pack, extracted to a folder in my C:\ drive using 7-zip and then pointed the "update driver" option from the Coprocessor item under Device Manager.

Now I can say I have a 100% functional Macbook 13" (mid 2009) running bootcamp 5 with windows 8.1, all from a triple boot rEFInd with OSx, Win8.1 and Ubuntu 15.04. Even my bluetooth mouse works across all three systems!

For those installing Win8.1 and getting the BAD_POOL_HEADER BSOD, the solution is to first test your entire RAM with memtest86 and, if no errors found, upgrade your bootcamp v4 to a v5.

Cheers! =)
