I recently replaced my aging Intel Core2 Duo 1.86GHz with an AMD Phenom II Black and a BioStar TA70GXE 128M motherboard (which is a real piece of shit, I would not recommend it to anyone). I could not find RAID drivers that allowed me to install Windows 7 64-bit (or even 32-bit), scouring the Internet led to a lot of perplexed posts about why it would not work. One suggestion that apparently works is to install Windows XP 32-bit with the supplied RAID drivers, then upgrade to Windows 7 64-bit. I was about to do that but I stumbled across an older set of AMD SB7XX RAID drivers today that caused Windows 7 setup to FINALLY detect my RAID/0 array. Here’s hoping to no stability problems.
The drivers I found can be downloaded from my web site: ATI_SB700_SATA_Slipstream.zip
