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: Yaboot is invoked by Open Firmware Finds a boot device, boot path and opens boot partition Opens /etc/yaboot.conf or a command shell Loads image or kernel and initrd Executes image See also Comparison of boot loaders References External links Former official website on the Wayback Machine Free boot loaders
