I guess he's right, Aros is probably the best solution since it doesn't emulate. Emulation is a very resource-demanding way to use a computer, a high-spec. computer is needed to emulate a low-spec. system (like Amiga, without offending anyone).
I've tried to install Aros from floppy to my Commodore 486DX laptop, with no luck. Then again it was merely a try I just put the floppy in to see what happened. Loading grub went fine but system halted halfway through Aros boot-up.
If you try let me hear whwat happened, I've thought of asking the guys over at Aros-exec or something what to do, I'm sure it's feasable.
FreeDos works great on the laptop thought, playing high-mem games and even using a mouse was no trouble.
