## NOTE: there's two different bootloader setups here:
## ppc/chrp: for normal PPC systems. needs 'addnote' run on yaboot.
## uses /etc/yaboot.conf, as is the default.
## ppc/mac: for PowerMacs. no 'addnote' (it breaks some Macs!)
## ofboot.b picks one of /ppc/ppc{32,64}/yaboot.conf for yaboot,
## thus automatically booting the correct kernel for the machine.
