- It`s possible since A3000...a reserved area was moved to ZorroII...
- I didn`t know there is a board available with additional ram bank.
- If it`s not hardcoded it would be usefull for A2000, too.

- There should be no memory located in the Z2 area, IMHO. There are nearly
- additinal 4GB of space. And a 64MB (or 128?) area is allready marked as
- onboard memory in memorymap...additional 128 for CPU board...should be enough.
