Pardon the noob question but I have not been able to have google answer for me. I am using the Samsung XP941 (PCIe SSD) as my boot drive on the ASRock X99 Professional motherboard. The OS is Windows 7 Pro and booting into the OS seems to be working okay. I want to add a couple SATA WD Red drives for storage but I want them in RAID 1. I figured the best approach was to reinstall Windows 7. I tried to reinstall windows 7 using the "F6 method." However during the Windows install the process would not recognize the Intel RAID drivers. Similarly I could not get the Intel Rapid Storage Technology to work. It responded with a hardware error when I tried to install the latest IRST. I did change the bios SATA controller mode to RAID before trying the above. What am I missing or am I limited to have these drives only in ACPI? Would a RAID controller card permit to do what I want? Many thanks.
