There are two ways to update your SM Bus Controller driver: Method 1 – Download and install the driver manually. Intel keeps updating drivers. To get them, you need to go to Intel’s official website, find the drivers corresponding with your specific flavor of Windows version (for example, Windows 32 bit) and download the driver manually. Feb 04, 2020 Download and run the Intel® Chipset Software Installation Utility so Windows. properly recognizes the SMBus controller. Note SMBus is the System Management Bus used in personal computers and servers for low-speed, system management communications.

This guide is useful if you have the following problem

1. You are running Vista or Windows 7 on a Macbook using bootcamp. It can be unibody/ Macbook Pro 13/ Macbook Pro 15 or any other screen size.

2. In windows device manger, you see missing SM Bus driver

Note: I have assumed D: as your CD drive below.

Steps to Follow

When you boot into Windows 7 for the 1st time, insert the 1st of 2 DVDs that came with your MacBook, the one labeled Mac OS X Installation disk. It comes with the Boot Camp 2.1 drivers, but normal installation fails with Windows 7 x64. Do a manual installation by double-clicing the Boot Camp x64 installer:
D:Boot CampDriversAppleBootCamp64.msi

Reboot and most things will be working, except for the SM Bus and Coprocessor driver problems discussed in this thread. The solution is simple. Run this file:
D:Boot CampDriversNVidiaNVidiaChipset64.exe
When it asks you which features you want to install, you only the “NVIDIA SMBus Driver” and “NVIDIA SMU Driver” need to be selected.

32 & 64 bit on unibody macbook pro

For the windows 7 32 bit version you need is to install the driver for the SM bus and Coprocessor after the regular bootcamp installation from the Mac OS X Installation Disk.

D:Boot CampDriversNVidiaNVidiaChipset.exe

For the windows 7 64 bit version you need to manually execute the bootcamp installation from the Mac OS X Installation Disk.

D:Boot CampDriversAppleBootCamp64.msi

For the SM bus Controller and Coprocessor.

D:Boot CampDriversNVidiaNVidiaChipset64.exe

After installation, navigating to the “Drivers and Printers” panel should show you that the Exclamation Sign is no longer displayed on your computer without even having to reboot.

The original Boot Camp driver for the MacBook’s Multi-Touch Trackpad is quite buggy. As a final step, upgrade to the latest version.

After performing these steps, everything seems to be working for me, including the function button row. I got an overall Windows Experience Index score of 4.4, determined by the Gaming Graphics sub-score.

The “Disk data transfer rate” determined by the Windows Experience Index was 5.4, and I didn’t have to disable Write Caching as described above to get this result.

After installation, go to Device Manger and you will see the SM Bus installed.
