Don't blame yourself, Hyperion and followers promote OS4 as being "Amiga" so it's hardly your fault that you assumed it would work on an Amiga.
It does, provided your Amiga is (1) one of the models listed and (2) has the corresponding PowerPC based accelerator listed. It runs just fine on my A1200 with BlizzardPPC.
It's unfortunate that browny misread them as implying only the 4000 required any such card.
Personally I'd have worded the requirements differently:
* A1200(T) with BlizzardPPC
* A3000(T)/A4000(T) with CyberstormPPC
Even then, I guess someone might misconstrue that their 3000 doesn't need one.
I wonder if anybody has tried it on an A2000 with the PPC prototype plugged into the 2060 board? It worked in OS3.x/WarpOS...
