Hello, new here. I recently purchaced a new machine. HP Pavilion a1720n Desktop PC. I do extensive work in audio (composing, tracking, mixing, mastering pre/post), and cannot be bothered by the "newness" and lack of audio drivers for Vista, so installed XP Pro Sp2 to an extra IDE drive I had. (Vista is of course on the SATA). The specs to my motherboard can be found here; http://h10025.www1.hp.com/ewfrf/wc/genericDocument?lc=en&cc=us&docname=c00379422 I do not need to install XP to the SATA drive. I simply need XP to see the SATA drive as a secondary data drive (to store my audio files - read/write methods in audio work need a second drive for audio). I have looked all over, back and forth for drivers to install on my XP drive to allow it to see the SATA drive, to no avail. And all google searches, just tell ways to install XP to an SATA drive.. I hope I didn't make that too long. Thanks a ton for the help. I really need it in this case.
