J25

[theorbtwo]

I did a bit of beeping-out of J25, the 20-pin unpopulated 0.1inch header between the ethernet magnetics and the ethernet connectors. Unsurprisingly, it duplicates the rj45 connectors, and does nothing else, so I'm not going to put any more effort then I already have into it, but here's what I've got so far. Note the equals signs: because the magnetics connect two pins with a low-resistance (at DC) connection, I'd need something more complicated then a multimeter to figure out which of those two rj45 pins is connected to which of the two j25 pins.
