If you have a Cyberstorm board then you could use BlizKIck, it rocks alot... otherwise try one by one every softkicker there is on Aminet and sooner or later you'll learn what is better than others that are crap (I can't tell you because I've a Blizzard 1230 on my miggy, but read on).
On my A1200 I use BlizKick to softkick ROM 3.1 + some patches: I took some stuff from 3.9 BB2' ROM Update (with romupdatesplit) and I use them as modules for BK (exec.library, FFS, scsi.device, and others I don't remember) (because I have just WB 3.1 and don't want to install 3.9 with just 16MB fastram), and all progs (even WB About) claims I have Kickstart 45.20 (that is, this is the version of exec btw), so WB About titlebar reads "ROM 3.9"... So Kickstart 3.9 exists! or kinda of...
