You are loading a 64bit operating system from what I can tell.
Go back to your manual.
Find out the maker of your onboard Sata chipset
(eg >Promise< or >Silicon Image< for instance)
Go to respective maker website and download latest 64Bit RAID (not basic) Win 7 driver.
Unpack/unzip the drivers to a dos formatted usb stick.
Stick the usb stick in a port and your raid drivers should auto-load if you are lucky as you restart the Win 7 64bit dvd.
