I must admit I do not know anything about the MAC, so I have to depend
on what others write.

Upgrading OpenCBM: Depends on how you installed it.
- You need the v07 firmware (get it from here:
- Use the following command-line:
xum1541cfg update xum1541-ZOOMFLOPPY-v07.hex
(while having the file xum1541-ZOOMFLOPPY-v07.hex you just downloaded in the directory
where you are running from)
You should get an error message saying something that this will result
in a downgrade, and it will abort.
If you get this message, you can execute the downgrade by using:
xum1541cfg -f update xum1541-ZOOMFLOPPY-v07.hex
("-f" for "force)
