To contribute, I have uploaded the ULI220 file with the RAID controller driver in the following link: MEGAUPLOAD - The leading online storage and file delivery service
I can get my A8r32-MVP Deluxe to recognize my Raid-0 drive now and able to finish the rest of Windows 7 installation.
When Windows 7 say no drive detected, click on "Load driver" and browse the USB or CD-ROM where you copied the ULI file into. Then point to the following directory to load & install it.
Hope this resolves the RAID issue for any A8R32-MVP Deluxe owner and/or M1575 chipset user when installing Windows 7.
