I've been trying for a couple of days now. I've got windows 7 installed on a standard IDE drive, I've got windows recognizing my array through the onboard SATA RAID controller, but I can't find anywhere in the bios to set the SATA RAid mode... is this even an option on the GK K8N-SLI?? I can't beliebe I've got all this working and I'm getting 30MB/s transfer from drive to drive over the same controller.
