   The proper thing to do is:
- Format a disk from the Finder. (It should lay down the boot sectors.
  If it doesn't, then use an older ProDOS 8 program like Copy II Plus
  to do this)
- Copy the file 'P8' in the system folder on a GS/OS volume (usually
  the boot volume) to this 5.25" disk.
- Rename this P8 file to ProDOS
- Copy other programs to disk. Make sure at least one has a name
  ending in '.SYSTEM'

   The ProDOS file on a GS/OS volume is radically different from the
file of the name name on a ProDOS 8 volume. The GS/OS one does things
like checking for the '8' key (to see if you want to boot into ProDOS 8),
then either runs the file system/START.GS.OS or system/P8 depending
on which one you want. */system/P8 is a copy of ProDOS that can be run
on _most_ pre-IIGS's. If the target //e is not enhanced, the P8 file
from GS/OS system 6.0 or later (maybe even some 5.0.x's, not sure)
won't run, unfortunately.

   Your solution of taking an old disk that you know works, copying off
the ProDOS file, and all should be just fine. There really isn't much
new in the later versions of ProDOS 8 that's needed for //e types.
