The Insider does *not* autoconfig and most products that sit inside the Amiga do not.
The boards reside in the $c00000 address space which is tested in a special way
when the Amiga powers up. All the Kickstart does is test memory starting at $c00000
every 64K or so by writing incrementally to those locations - if it gets a bus error
it knows that there's no ram there, otherwise it adds it to the memory free pool.

I really resent those manafacturers who claim their product "auto-configs" when they
reside in this location - they didn't do all the hard work and debugging like those
who spent the time to get their products to really auto-config. Take a look at the
Insider - not autoconfig PALs on there...
