Yaboot (yet anotherboot loader[1]) is abootloader forPowerPC-based hardware runningLinux.[2][3]

History

[edit]

In 2009, maintenance by Paul Nasrat was handed over to Tony Breeds.[4]

Hardware support

[edit]

Support includes theNew World ROMMacintosh andIBM RS/6000 systems. It does not support the "OldWorld" PowerMacs.[2]

Booting procedure

[edit]

It is built to run within theOpen Firmware layer common to most such systems instead of working as aMac OS 9 program like its predecessorBootX.

Yaboot is similar toLILO andGNU GRUB.[5] Yaboot uses the following steps to boot:[3]

  1. Yaboot is invoked by Open Firmware
  2. Finds a boot device, boot path and opens boot partition
  3. Opens/etc/yaboot.conf or acommand shell
  4. Loads image or kernel andinitrd
  5. Executes image
