The CodeSet contains drivers and software for everything. (Linux, FreeBSD, VMWare, Windows). It's essentially an updated version of the CD that they ship with the RAID controllers. LSI bought out 3ware so all the support and latest downloads have moved to their site. They're on version 9.5.4. What I do is I download the latest drivers drivers and put them on a flash drive. When Windows is booting it'll asking you to load a driver if you have a RAID controller. Plug in the flash drive and click on the driver file.

The only two things you need are the Windows Drivers+3DM2 Software listed under Support and Downloads. (Software and Driver subheadings)
