It still reports the same error about mode 4. I double checked that the change to the modprobe file was correct, and just for superstition I rebooted as well. I don't see any mention of parport in any of the config files from pico, so I'm not sure how it knows to load that driver. It does load hal_ppmc, so maybe that drives the parallel port.
