Hello all, I've looked through the forums here as well as Googled around, but can't find what I'm looking for. I have a new Dell Inspiron 531, and I want to install a Lite-On DVD drive (via SATA). BIOS does not recognize the drive, so Vista doesn't either. I've reseated the cables and tried different SATA connectors on the board. Still no luck. What am I doing wrong? Any suggestions? Thanks in advance!!
