  Apple (and briefly a few other manufacturers - Power Computing, for
  example) makes a series of Macintosh computers based on the PowerPC
  processor.  They divide into several categories: Nubus, old world PCI,
  and new world.

  Nubus systems are not currently supported by debian/powerpc.  The
  monolithic (LinuxPPC) kernel architecture does not have support for
  these machines; instead, one must use the MkLinux Mach microkernel,
  which Debian does not yet contain support for.

  These include the 6100/7100/8100 line of Power Macintoshes.

  This category contains most Power Macintoshes with a floppy drive and
  a PCI bus.  They use an older, buggier revision of the Open Firmware
  than the new world machines, but can boot Linux either directly from
  Open Firmware (via Quik), directly from the MacOS ROM (via miBoot), or
  from within MacOS (via BootX).  Of these, only the BootX method
  flexibly supports dual-booting.

  This includes most 603, 603e, 604, and 604e based Power Macintoshes,
  including the 7200, 7300, 7500, 7600, 8500, 8600, 9500, and 9600.


  11..44..  TThhee nneeww wwoorrlldd ssyysstteemmss


  This category contains the Power Macintosh systems from mid-1998
  onwards.  They use a more complete Open Firmware bootloader, which
  supports booting from a network or an ISO9660 CD-ROM, as well as ELF
  binary loading.  These machines can boot Linux either directly from
  Open Firmware (via Quik, or the far more powerful yaboot tool), or
  from within MacOS (via BootX).  BootX is far less reliable on the
  newer systems, and the use of yaboot is highly recommended.  The most
  flexible of all currently supported bootloaders is yaboot, which
  supports loading a kernel and ramdisk directly from an ext2 partition,
  as well as dual-booting MacOS, and installation without modifying Open
  Firmware's settings.

  These machines include most G3 systems, the iMacs, and G4 systems.
