I have a Raid 0 array and one jbod drive on the SATA controller along with the Samsung SATA burner. If the SATA is not set for RAID, then the mobo can boot off the DVD drive. But I must use RAID mode and I bought this board for the 6 SATA ports, did I just blow 0 for nothing? I can boot off SATA on my old mobo but JMicron is flaky to use so I thought I'd just buy a new mobo. I am having a shit day here.
