    Greetings, FreeBSD Forums:

    I have an iMac on which I've managed to install a variety of Linux distributions successfully, including Ubuntu, Linux Mint, and Mandriva. Recently I've become interested in the BSD side of things, so I decided to install FreeBSD. I burned the 8.1 i386 ISO to a DVD and booted up. The installation seemed to go well (I used all the defaults by pressing A) until I clicked the final 'Install' button.

    I received the error
    Code:
    Unable to find device node for /dev/ad4s1b in /dev !


    I rebooted several times to try again, but to no avail. What could have gone wrong?

    if you can get to a loader prompt and
    kdload the following
    geom_mbr.ko
    geom_label.ko
    geom_bsd.ko
    (I've forgotten how, see other threads mentioning
    all three of those).
    Then the install *might* proceed. Alternately,
    use a 7.x install cdr, and in the "options" choose
    an 8.x release (get the
    default name from the 8.1 cdr?) from a server if you can input the
    connection details somehow. Other workarounds...
    Not in any position to write a guide though.
    see other threads maybe.
