As @techie007 posted, this question is quite similar, and the result is an exact duplicate. For reference... (this site)
With the motherboard set to RAID mode, put in the Windows 7 DVD and boot into the Recovery Environment. Go to the Command Prompt, type REGEDIT and press Enter. Expand and select HKEY_LOCAL_MACHINE, select File->Load Hive..., select x:\WINDOWS\System32\config\SYSTEM. Name it whatever.
Next, go down to the imported hive, then you'll see ControlSet xxx. Expand to Services, then iaStorV. On the right hand side for each ControlSet, change the Start value from 3 to 0. When you are done, select the top of the hive you imported, select File->Unload Hive..., and I can then boot to Windows
After booting into Windows, I went to Intel's RST website to download the new version of their software. Once I installed that and rebooted, I could follow Intel's RST Instructions for enabling the SSD cache for the Hard Disk Drive, even though another SSD was the boot drive
