I just finished my first computer build and I have one problem I cannot figured out how to solve, first I install 2 SSD in Raid one for the operating system and everything work fine.  I then install a IDE hard drive, I then get a message in the Bios that I need another drive to put it in Raid.  I don't want raid, I just want one storage drive and I cannot figure out how change the bios with out my computer not wanting to boot to windows.  I hope this make sense.  I would appreciate any help I can get.
Thanks
