Raid Drivers Windows 7

Okay, so i been trying to install two 640 gb drives in Raid 0. I was able to create a raid volume in the BIOS RAID Configuration Utility. Afterwards, I tried to install windows 7. I had the intel raid drivers on my usb drive, but when i pressed f6 it could not recognize it. I manually browsed to where the files were stored. Then, I tried to install the raid device drivers. It loaded but then said said:

"To continue the installation, use Load Driver option to install 32-bit and signed 64-bit drivers. Installing an unsigned 64-bit device driver is not supported and might result in an unusable Windows installation."

Despite that, my raid drives, which i had called Volume0 (default name), still showed up as a disk drive in which I could install windows. So i proceeded to install windows 7 64 bit in that partition. So is my raid 0 actually working even though i didn't install the raid drivers before installing the OS.

Intel....google search Intel Raid Matrix Sotarage Manager it should come up
