Just need to decide where its safest to add AROS! :-)
In a vmware player virtual machine. On nowadays hardware, with SSD drives and blazing fast RAM, processors and video cards, AROS would use just a fraction of all this power. So there is no need for a native installation on the bare metal, other than for a quick "oh, it's soooo fast" test.
You'd loose only the 3D hardware acceleration option this way, but recent video cards are unlikely supported by AROS anyway.
