Download chipset package here: https://downloadcenter.intel.com/download/26132/Intel-Chipset-Device-Software-for-Intel-NUC-Windows-10-and-Windows-7-8-8-1
I know the title of the page says that it's for the NUC stuff, but it's still valid for Z97 and such.
Put SetupChipset.exe in something like C:\Temp
Create a folder like C:\Temp\Extracted
Open an administrative command prompt, navigate to C:\Temp ( CD /D C:\Temp ) and type:
SetupChipset.exe -extract C:\Temp\Extracted
The only two folders you should need for Z97 are 'haswell' and 'lynxpoint-hrefresh'.
I'll give it a try tomorrow. Out shortly for the rest of the day.
