I read your Understanding and Updating Chipset "drivers"
article and think I got it pretty well down. My understanding is that the .inf install utility is only needed if the operating system didn't detect a device (in device manager).
When I clean install Windows 7 to my T61 ThinkPad all the devices are detected by Windows (no yellow warnings in Dev Mgr). So in this situation there is no point in running the Intel Chipset Software Installation Utility if I understand correctly.
Would the Intel .inf files have more accurate information on the devices than the Microsoft ones on the Windows install disk and if so does it matter?
Just wanted to clear this up, I think many people think they have to run the intel .inf install utility even if the OS install recognizes all or most of the chipset components.
