I finally got it working! Thanks for all the info guys!
To get it working I did hook up my old 1084 and start SKick before anything else was loaded. I use a VGA monitor normally so I couldn't access the Early Boot Menu without BootControl which adds a ROMTAG that I guess is no good when trying to softkick.
OS3.9 is up and running on this miggy now so I'm happy :-P
