So far I can't complete the Icaros install without a lockup and my keyboard doesn't work.
The same USB keyboard is fine on an Amiga with Poseidon.
It worked fine on my HP USB keyboard, I haven't tried an install with my Logitech wireless yet. I haven't bothered reinstalling until they have more full graphics drivers.
I doubt it is the keyboard causing the trouble. Did you try the try before installing option, that will let you know if everything is compatible.
