Ok, here is the RAID problem I am having. When I put ICH10 to RAID mode in the BIOS, regardless if Jmicron SAS is enabled or disabled, when it gets to the part where it should load from CD to start a fresh OS install, it gives me a DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER. When I put the ICH10 back to IDE mode everything works fine. I have the two HD's that I want to RAID plugged into SATA 0 and SATA 1 spots. I have tried everything and can't figure it out! I am probably missing something stupid but... any ideas? It did the same thing on the P03 BIOS that came with the board and I have not tried G13.
