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 ==
