     A .do disk image is a .dsk disk image.

     The only difference is that ".do" says: "This is a disk image using DOS
3.3 sector ordering"; whereas ".dsk" says "This is a disk image which may use
DOS 3.3 or ProDOS sector ordering". An emulator is supposed to check a .dsk
file to discover the ordering; it does not need to check a ".do" or .po"
file.

     Over the years, the ".dsk" suffix has come to be accepted as equating to
".do" because nearly all 5.25" .dsk images use DOS 3.3 sector ordering. The
ADT transfer utility has helped to establish this convention since it insists
upon dealing with ".dsk" files in DOS 3.3 order. (The actual content of the
image can be DOS 3.3 or ProDOS or some other DOS.)

     Anyway, you can just change the name of narf.do to narf.dsk.
