I installed Windows 7 on a user's Macbook Pro yesterday (Aug 2010 model I believe) using Boot Camp, then I used the Mac OS X disc to run the Boot Camp Drivers installation. I then restarted as normal and went about the myriad other installs, when I entered devices and noticed the "!" symbol on the computer.

Lo and behold, 3 drivers were missing: Coprocessor, SMBus, and a third that I can't recall at the moment. I found several references to the missing Coprocessor and SMBus online, but the posted solutions (to install nVidia drivers, to run the Intel Update service, to let Windows 7 try to find the drivers itself) all failed (some of the driver installations reported the incorrect hardware, some installed but didn't resolve the missing drivers in Devmgmt).

I've installed Windows 7 on 10+ Macbook Pros and never once run into missing drivers after installing the boot camp driver pack. Everything seems to be working fine: display, ethernet and wireless, sound, track pad, eject button all function perfectly, but the ! in Device Manager are driving me crazy. Any ideas?

have you tried repairing or reinstalling with the install discs? –  Graeme Hutchison Mar 22 '12 at 16:31
