Yeah, on a Real Amiga (tm) AROS is simply a free Kickstart replacement. That is Toni's (one of the two key AROS68k developers) aim.
If one wishes, then they can use AROS's extra features, but that is optional, and I expect most users of AROS68k will just use it as a free alternative to the old Commodore ROMs.
Feel free to download the AROS sources and build yourself a custom Kickstart to suit your own needs.
The issue we need to workout now is, why doesn't it boot your machine?
You have AGA.
You have 020.
You have 4+Meg of fast RAM.
I can't see why your machine doesn't work... Are you using an Amiga International or a Commodore A1200?
