Some SCSI cards do not function with the Fusion Forty, you can get the newer ROM update to fix that....
What version of the Fusion Forty Plug 'N Go ROMs do you have? (Hit ESC on bootup and enter the F40 menu to see) If you have older ROMs you cannot use Kick 3.1, you need V 3.4 of the PNG ROMs (I have them available see my site)
