Is it possible to cross compile (Maybe I mean install)  netbsd on a Mac 
OS X machine or Windows XP machine, and generate the proper install 
information code on a target machine (Mac Performa 460  - a 03 machine, 
no fpu)

perhaps I need to understand the concept of cross compiling, and what 
tools andwhatever else I would need to get this going....

I want to end up with netbsd running on the Performa 460 with color an 
some type of x-window GUI KDE would be nice, but I am realistic, it's 
an old machine .... any gui would be ok...
