The Dell manual does not include anything about this model's BIOS. I would suggest asking this question on the Dell Community, Laptop Section. People there familiar with your Dell and what can be changed in the BIOS.

Why do you want to change the SATA? Most Notebooks can work only with the hardware in them, have settings accordingly or are blocked from change and usually the only physically-changeable things are the HDD [either PATA or SATA], Memory/RAM and Optical drive.

The only worthwhile change might be to enable AHCI for SATA controller to reinstall the OS, or without reinstalling you'll need to take these steps once you change it in BIOS: http://www.sevenforums.com/tutorials/61869-ahci-enable-windows-7-vista.html
