    I have AMI BIOS that does not have 32 Bit Transfer Mode or S.M.A.R.T for
    Hard Disks enabled by default.
    Why would I not want these enabled? I would think that I would. What I've
    read about these features seems to enhance disk performance. (I have a new

    SMART can tell you if there is a problem with your hard disks. This is a
    good thing.
    I put 32 bit transfer mode into Google and came up with this article at:

    This BIOS feature allows you to command the IDE controller to combine two
    16-bit hard disk reads into a single 32-bit data transfer to the processor.
    This greatly improves the performance of the IDE controller as well as the
    PCI bus.

    Therefore, it is highly advisable to enable 32-bit Transfer Mode. If you
    disable it, data transfers from the IDE controller to the processor will
    only occur in 16-bits chunks.

    I think that pretty much says it all.
