I'm afraid you'd need to contact Elesar for support on their product
(especially as we have offer our own, supported, "Graphical Linux" product
for Titanium/TiMachine for quite a while now), but I can confirm that the
Linux card is meant to fit in the micro-SD slot at the rear-left of the
motherboard.
With a little care, you can remove the 4 motherboard screws and slide the
board gently forward (with an anti-clockwise twist) without needing to
completely disassemble the machine. This will provide access to the
micro-SD slot.
