Amiga Memory Map

[<fh...@at...>]

Can someone explain to me how APUS is using memory
in relation to a driver?  If I request a region, 
check_region()/request_region(), for I/O where
will the kernel most likely map that memory.  

Also on the APUS Amiga how to a get memory to be non 
cachable?

I may have asked these questions before.  If so....sorry.
