Thanks for your reply, reason for my post is because my PC will not boot up. the first option in the Bios is Hard Disk Boot Priority, pressing Enter and Bootable Add In Cards appears, I can change the boot sequence after that but the master 0 and slave 0 show as NONE in the Detecting Drive window.
As I'm not sure of the reason for the ADD In Card and I can't change it I wondered what it's purpose is, thanks Roy
