I have a Gigabyte GA-K8NS Pro motherboard. I have 3 SATA HDDs, 2 set up in RAID on one of the onboard controllers. The other hard drive is just a data disk and was running on the 2nd onboard controller. However, that 2nd controller decided to stop working. I bought a PCI SATA controller, installed all drivers etc... and hooked up the data drive to it. But now whenever I try to boot with the data drive connected it tries to boot from the data drive, and won't load the OS from the RAID set. Is there a way to force the computer to boot from the onboard controller rather than letting the PCI controller take precedence? Thanks!
