#VD0:
Kurt,
vd0: won't recover if the memory is cleared. See Larry's reply to you
about using ADDMEM. Out of curiosity, which memory board are you using? Most
of them will auto-config under v1.2 of the Amiga Operating System and don't
need to be ADDMEM'ed and that would clear up your problem.
If you are using a board that doesn't auto-config, you may not be able
to get vd0: to recover until you find a new program to add the memory to the
system without clearing it.
Don
