100D: fix INPUT_ENABLE_IMAGE_PHYSICAL_SCREEN_PARAMETER (display filters working)\u000a\u000ahttps://www.magiclantern.fm/forum/index.php?topic=16040.msg202397#msg202397
This procedure will enable the BOOTDISK flag in your camera's Flash ROM, allowing it to load and execute custom code from the memory card. A copy of the original (unmodified) ROM contents will be saved to the card.
Magic Lantern will run from this card; it won't replace your original firmware.
This procedure disables the BOOTDISK flag. You will no longer be able to run Magic Lantern, unless you reinstall it.
Some settings changed by Magic Lantern might be persistent; this procedure will not reset them. To restore the camera to factory state, you may also want to clear all camera settings and custom functions from Canon menu.
