As an answer to the question about booting floppies, all you need to do is turn off the 68020 cache before inserting the uninitializing floppy (or selecting erase disk).

One problem I found tiresome was that everytime you want to select something on the CDEV, you can't just close the Control Panel window from there....that would elicit a crash.

If something doesn't run, turning off the 68020 cache (through CDEV) will fix it right up...no reboot needed.  
Hope this helps...
