No when I do the setup from windows that option is greyed out, and when I try to do a install from dvd it says that i could not get any information about my disks (i can't get to that page) The Vista does not have a upgrade option. So, if you start the Vista in Windows, it will try to load the Vista with the "Load Drivers" greyed out. Also, it won't upgrade your Windows, but rather create a sub-directy called Windows.old and put all the old files in the Windows, Program Files and Document and Setting directories in the Windows.old directory. Basically, no upgrade but a new install with all the old stuff still remianing. Install the Vista from a bootable disk. You will find that it does not show up any SATA RAID drives, but the "Load Drivers" is avaible now (not greyed out). Load your drivers and you will see your SATA RAID Drives. Install on seperate drive thus keeping your old Windows, thus having dual operating systems. Hope this help. All the Silicon Valley SATA drivers are available on the net. If you still can't find them, then let me know and I will upload them for you.
