Yaboot (yet another boot loader) is a bootloader for PowerPC-based hardware running Linux.

History

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

Hardware support

Support includes the New World ROM Macintosh and IBM RS/6000 systems. It does not support the "OldWorld" PowerMacs.

Booting procedure

It is built to run within the Open Firmware layer common to most such systems instead of working as a Mac OS 9 program like its predecessor BootX.

Yaboot is similar to LILO and GNU GRUB. Yaboot uses the following steps to boot:

1. Yaboot is invoked by Open Firmware

2. Finds a boot device, boot path and opens boot partition

3. Opens /etc/yaboot.conf or a command shell

4. Loads image or kernel and initrd

5. Executes image
