Hi puntoMX We had some private testers going at the "beta", and now that the official AHCI is released by intel, we put up a driverpack for mass storage including that new driver. I will eventually be able to personally test all BIOS settings in a ICH7, an ICH9 and an ICH9R. XP live tests take time, and I wish I had 46 hours in a day. What I am saying is that driverpack.net have a testpack with the latest, ready for integration, and we are interested about comparatives and (also) on how it does without us hacking into files. (you know that when it works well without a hack, you don't want to break it.) I promised we would not forget you people, and I hope intel made the right choice for you. You see, IF it can be done by F6, it can be done by driverpacks. (I will also soon look at adding USB drives to driverpacks, so that ...) EDIT.. my personal tests so far were on a hi end gigabyte mobo, ICH9R, in a raid5 array. (blot in that HW is a Jmicron duplicate for tertiary controller. mobo has 8 sata rails.). other testplank is an abit with ICH9 (which does not offer AHCI in BIOS mobo has six sata rails.) I am saying I've got some freaks to test. (I have stored 7 issue rich testplanks). Some of these boards should not have been sold to public. I kept these as litmus test.
