Where do I find the RAID drivers that I need to apply during Windows 8 install?

I have a hp pavilion ultrabook 14-b112eo and after raiding the harddrives I need to provide the Windows 8 install with RAID drivers. I have looked at the this page:

that provides the drivers for my laptop, but I can't find the appropiate ones. Any ideas?
