HI, I am trying to install Windows 7 64 bits on a intel ich7r raid 5 group disk, but I am having problems. The installation process does not recognize the (raid) disk. When I load the Intel F6 RST driver, an error appears showing that "the drive version is incorrect. Contact the manufacturer". The raid is OK and bootable. The SATA MODE is RAID on bios. Is it realy needed to (pré) install the Intel ich7 RST driver in a new Windows 7 installation?
