I beleive he is correct, although i didnt look it up. One thing tho, if you find that you want to get the most out of a new ATA66 HD, then you can always get yourself a controller card. If you havent purchased the new HD yet, you can even consider an ATA100 HD, and get a controller card that can handle them.
Enjoy,
