The modified ipdf needs to be copied to your iliad file system. I created a little set of installers of the various versions to make it easier to switch and get the features I need at a particular point in time. You can get them
here. Just unzip this to somewhere, e.g. your CF, and then navigate to the folder (on your iliad). You will see four installers in the contentlister, one of which restores the original iRex ipdf. You can only have one current version, so it shows the date and time of that each version was copied across so you can figure out which is the current version.
