I cannot install windows 7 x64 with unsigned AMD RAID driver

Trying to install Windows 7 Ultimate x64 on an ASUS M5A97 mobo with AMD SB850 RAID, two WD 750GB drives configured as RAID 0. No drives are recognized by W7 install, so I choose Load Drivers. I put the drivers on a USB stick. Install finds the drivers there, starts loading them, then comes back with "Installing an unsigned 64 bit driver is not supported and may result in an unstable Windows installation." Round and round she goes. I downloaded the latest drivers from ASUS website. I'm willing to take the chance on loading an unsigned driver Bill Gates! I saw other posts that recommend clicking Repair instead of Install, but I don't see where that option is. All I am given as options is Upgrade or Install. Choosing Upgrade tells me to boot Windows first. But this is a brand new install so... I see this problem has been ongoing for at least the last 18 months; surely someone has a solution that actually works?



The SB950 chipset was released in 2011, so is unlikey to be included in the core win7 release

AHCI chipset drivers were released far earlier


You might get further adivce re the SB950 chipset / raid driver and the apparent 'unsigned issue' if you were to post to MSDN Technet http://social.technet.microsoft.com/Forums/en/category/w7itpro

Personally I wouldnt recommend using ether AHCI raid or the motherboard chipset amd raid drivers, from experience I have seen to many problems caused when using software raid, from raid going out of sync, to in the worst case loss of data. I've seen this happen with various motherboards.

If you want to use raid buy a dedicated hardware raid card, a decent one will cost some $350
