Mine is a D845WN... no onboard graphics and I've disabled the onboard sound in the BIOS in favour of an Audigy 2 ZS Platinum Pro.
In the executable install package I've used in the past, there doesn't seem to be a pick-and-choose option. However, I also keep the alternative *.zip download, for manual installation. I've never actually used that method, but I imagine you could simply choose which ones to install instead of putting them all in.
I'm just wondering if it's worth bothering with Intel's drivers at all, anymore. Perhaps if I had a really new board, but this thing is a couple years old now, and Intel stopped issuing updates quite a while ago. I'd hope M$'s own drivers must be on par with Intel's at this point, for my archaic hardware, if indeed there was ever much of a difference.
