If you need to change floppy size from 5 to 3 or 3 to 5:

1. Put a high density disk non-write protected floppy disk into the A: drive and put UTILITIES DISK 3 into drive B:.
2. Log to the B: drive by typing:
   B: <ENTER>
   Next, type B:FORMAT A: /B -- when the format is complete, copy the entire contents of the STARTUP disk to the newly formatted disk in the A: drive by typing:
   COPY B:*.* A:
3. For the other two disks just copy them with the COPY command to disks of the proper size (these disks do need to be formatted but not necessarily with the Concurrent Dos FORMAT program -- any high density, non-write protected, already formatted disks will do).

You now have a complete set of Concurrent Dos in the proper disk size to boot from and install.
