Yes, true. This where the boot fails, also Oberon-0 never gets to the
command loop, as it fails on a corrupt file system.

Could it also fail on blank card?
It does some init of the root directory.

PROCEDURE Init*;  (*initialize the file system if needed*)
    VAR a: FileDir.DirPage;
  BEGIN Kernel.GetSector(FileDir.DirRootAdr, a);
    IF a.mark # FileDir.DirMark THEN
      a.mark := FileDir.DirMark; a.m := 0; a.p0 := 0;
      Kernel.PutSector(FileDir.DirRootAdr, a)
  END Init;
