To further explain this is what your website says using the Intel Driver Detection Utility
This was what the Driver detector on Intel's site was saying:
Product Detected Intel(R) ICH8R/ICH9R/ICH10R/DO/5/3400/6 Series SATA RAID Controller Current Driver Installed 126.96.36.1995 Newer Driver Available:
When I try to download from the link it is incorrect and not found on the site.
However, trying to go to the Download Center says a completely different driver version.
I have the same issue. The update utility states that 10.8.0.1003 is the current version but I can't seem to find it anywhere on Intel's site to download. The download link with the utility states the file is not available.
