so, ok, then. I have a folder with all the files. How do I add the SATA driver to the mix?? Just d/l it from Sony and drop it into the folder?? And when I do that, will that enable the installation to see the SATA drives?? Also, when I put the second 500gb SATA drive in, how does the computer know which one to boot from? I see no jumpers and no place in the BIOS to set that.
