    Default Driver needed for AHCI?

    I read on another forum that with Vista you don't need to install a driver for AHCI:

    "Since it sounds like you are installing vista, just use AHCI. Vista has built in support for AHCI, even in the installer. It will work fine without any intervention on your part.

    The only reason to use the IDE mode is if you are using an older OS without support for AHCI."

    Vista has support for AHCI features, one I know being NCQ, a Pre OS install driver is needed

    The only reason I see to use AHCI is if you want to Hot swap your drives, or if you want a slower boot time...... which you need to install the driver during OS installation.

    If your drive supports NCQ it will be used in vista with no additional drivers

    Sounds good to me. I don't need a slower boot time, so I'll stick with Native IDE, which is SATA, not really PATA, but SATA.

    I have been confused too about which modes to use. Still confused. IDE, but not legacy IDE? I get the part about only using AHCI if I need to hot swap.
