Silly question perhaps, but what ROM version is installed on the m/b?  You're going to need version 2.04 or better to install Workbench 2.1 or version 3.1 to install Workbench 3.1.  Check the 40 pin dip style chip to the right of the 68000 cpu on the m/b, if it reads 37.xx it's a 2.0x ROM while 40.68 would be a 3.1 ROM.

Also, there may be compatibility problems with the Fusion Forty and 3.1 ROM.  You need iirc the newer boot roms on the FF itself to autoboot a 3.1 bootable partition.  I don't have a FF but maybe someone else here can tell you.  There's also the BBoAH (big board of amiga hardware).

Forget about SKick and the ICD 2080.  ICD used special memory buffering schemes to make their controllers faster. I just tried SKick with an ICD AdSCSI, no go.  Crashed on boot.  There are probably going to be problems with the Fusion Forty and SKick as well, because if it's an older FF, its own software will to a rom reboot, likely conflicting with SKick (though it may by a miracle work). I'd chuck the 2080 if it gives you any trouble and get instead a GVP HD+8 or even C=A2091.  These are true SCSI DMA controllers and *should* work fine with the FF (though you probably should upgrade the plug n' go roms with the latest version for compatibility with 3.1 system roms). Get the real 3.1 system roms for your 68040 boards.  See TjLazer for the latest FF roms.
