Strange, blocks 0-2 overlap with block 3?

That's indeed not much...
Does this match with the output of the AmigaOS `showconfig' utility?

Amiboot walks the memory list at SysBase->MemList.lh_Head:

Chris, perhaps you can shed a light on what's going wrong?
Mike, I expect you can get it to work by using a memfile. Create a file
containing:
2097152
0x78000000 33554432
and use the Amiboot `--memfile <file>' option.
