    Um, wouldn't setting the password on a system in which the BIOS offers
    no ATA security support render the system unbootable? The BIOS would
    be unable to read the boot sector without first unlocking the disk...

    Since compliant BIOSes have already frozen the config by the time the OS
    boots anyway, the only reason I can think of for atacontrol to have
    security support would be if you're booting from some other media, i.e.
    floppy, CDROM, network, USB...

    It might also be somewhat useful for secondary (non-boot drives). *BUT*
    that would probably only work on machines where the BIOS doesn't freeze
    all the drives on startup.
