Latitude motherboard, unused socket, what might it be for?

Hi,

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
for?

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 ****

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.
Thanks,
Stephan
