Because it cannot be compiled under NetBSD. And it is just a temporary
solution. When amigappc ever reaches a usable state we should use/enhance
the port-amiga bootblock code.

Ok, so it would theoretically work. But I think that it is practically
useless to run PPC code in memory which is so slow as Z3 RAM.

Data-BATs, yes. ISI traps are not handled by replacing BATs. So the kernel
and maybe other firmware code it needs, should be covered by IBAT0 and

This should have worked. I have no more spontaneous ideas. You have to debug

Yes, write data into Chip-RAM (e.g. 0x1f0000), which you can inspect after a
