If you are installing a Serial ATA drive, connect the Serial ATA cable into the first open SATA slot on the motherboard, SATA1 first or SATA2 second. Connect the other end of the Serial ATA cable into the back of the hard drive.
If you are installing a Serial ATA drive as a replacement for an IDE drive, check the motherboard for an open SATA slot. If the motherboard does not have an open SATA slot, you can purchase and install a PCI SATA controller card or a SATA to IDE adapter.
If using a PCI SATA controller card, connect the Serial ATA cable from the drive to a SATA slot on the controller card.
If using a SATA to IDE adapter, follow the instructions for the adapter.
