    So can I assume that these instructions will work with any device? I
    realized that I didn't double check this:

    especially in the
    line for the boot loader where ad(1,a) --> da(1,a).

    I didn't double check that. I'll follow through the instructions again
    and make the correct change this time and we'll see what happens. I
    don't have a problem until I have to reboot. That is when the
    instructions want you to dd the first disk then add the first disk to
    the gm0 mirror. Both commands give me errors. THe dd command right after
    reboot gives "command not allowed". And the gmirror add command give
    "can't access provider". I'll try again and let the list know what happens.
