My PQ5 Pro board has 8 Sata connectors but only six of them seem to work like normal Sata connectors? E1 and E2 wont boot my system drive? in the bios there set to IDE are the E connectors only for drive expert? and can i use them if i use raid? as part of the raid set up? if not have i only got six Sata if i don't wont or need "drive expert EZ back up"
