    I have just upgraded my Latitude CPx from a 450MHz CPxH motherboard to a
    750MHz CPxJ.
    That was fine and it all works well.

    On the new motherboard I noticed a small socket near where the sound ports
    are, which looks like it's labelled 'JMDM'. Any idea what this socket is

    One thought was that it might be a for an internal modem, but I'm not sure
    where the phone cable would plug in if it was. The older m/b had a place for
    the socket but no actual socket.

    Regards, John

    I believe you are correct it is a socket for an internal modem but they are
    as rare as rocking horse shit

    Hi John,
    I found Your message, that You upgraded Your CPXH with a mobile cpu. I'am about to do the same. My question: Did You experience any problems with the sound cards. The CPXj uses the maestro 3 soundcard while the cpx h has the maestro 2. Some users found out, that the CPXj firmware doesn't work properly with the maestro2 hardware.
