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 Camp\Drivers\NVidia\NVidiaChipset.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 Camp\Drivers\Apple\BootCamp64.msi
For the SM bus Controller and Coprocessor.
D:\Boot Camp\Drivers\NVidia\NVidiaChipset64.exe
The only problem i have right now is that the installation disk won't eject. not in computer by clicking eject or by clicking the eject button on the keyboard. all i get is:
An error occured while ejecting 'DVD RW Drive (D
WindowsSupport'
the smiley was not there before, but the forum doesn't know better.
I will try after the reboot the trackpad update requires to eject the DVD. I think this is only a fluke, but if not i will let you know. Everything else works great so far. My keyboard buttons like volume, brightness etc work fine as well. just not the eject button at the moment as mentioned before. l8
