go to https://www.asus.com/Motherboards/P5W_DH_Deluxe/#support
and download the motherboard installation guide(multiple languages)
and P5W DH Deluxe User's Manual for English Edition (E2557)
and follow instructions like
saving and updating bios
and it should have info on what sata slots should be used or something like that.
Good luck and ask questions if needed.
I will be here the whole time.
