I checked the readme file at http://downloadmirror.intel.com/20624/eng/iata_10.8.0.1003_readme.txt and http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=20625&ProdId=2101&lang=eng however I do not see any mention of Microsoft* Windows* Vista* not being supported by the F6 drivers we provide.
Keep in mind that these drivers are only for the operating system installation stage, that is why they are still called "F6 drivers" because in Microsoft* Windows* XP or similar operating systems, you had to press F6 to load these third party drivers (as they were not provided by the Microsoft* installer) and the only possible way to load them was using a floppy diskette. Now, in newer operating systems like Microsoft* Windows* Vista* or Microsoft* Windows* 7, yo do not need to press F6 and you are not obligated to use just a floppy drive to load that driver.
If the operating system is already installed, then you can just install the Graphics user interface and that will update the drivers installed. It is posted here:
Concerning the RAID option ROM, which is the Control I menu that is shown before the operating system loads during POST, this is updated by your motherboard or computer manufacturer, usually through a BIOS update. If you would like to update this portion of the RAID controller, you need to refer to the system manufacturer or motherboard manufacturer directly for an update.
