I'm running regular Fusion V3.1. I couldn't find the iFusion, but a cover cd had Fusion on it, so i went for it. I'm running OS 8, it runs OK, i'm tempted to connect a scsi drive to it, but I think it won't get much faster, since i've got it running on a harddrive connected to my FastATA ZIV.
I'll try maybe next week to connect a scsi drive to it. It's all running in my Towered A1200 quite nicely. Anyone know how I can hide the partition for Fusion? It's HFS and is worthless on my desktop.
