In , you have to load the SATA drivers before you can install Windows. XP by default does not load SATA drivers. You would need a floppy disk with SATA drivers of your HDD on it. When windows loads all the drivers on the beginning you have to press F6 and then load the drivers and then continue the installation.
Otherwise, in BIOS you have an option of selecting how you want to use your SATA drive. You can set your option to IDE in the BIOS before you start XP installation.
