    No. In order to run MorphOS, the APM setup on PPC Macs must contain at least the following:
    - a small HFS partition containing the MorphOS boot.img, set to non-bootable
    - a larger SFS partition containing the MorphOS system files, set to bootable

    The reason for this setup is that the Mac OpenFirmware can read HFS but cannot read SFS, so it loads the boot.img from the HFS partition. The boot.img in turn can read SFS and thus starts the MorphOS system from the SFS partition. The 'bootable' flag is required by the boot.img, not by the OpenFirmware, that's why the SFS partition must have it and the HFS partition must not have it.

    The MorphOS CD/ISO should be in ISO 9660 format with Rock Ridge or Joliet extension.
