    There are ways to do that, but in order for that to work at all you
    need to have BIOS support. Some of the ATA ``RAID'' products work
    like that: they have BIOS support for mirroring/failover, but the
    operating system has to do all the work once it's booted. FreeBSD
    supports these controllers reasonably well, and they are quite
    economical.
