So, nothing special in recording a bootable cd. Hmm, then why can't i boot
it ? the ISO is definitely bootable. I have `enablecdboot' in yaboot.conf,
and select that while booting, it seems to try to boot from cd-rom, but
falls back to the menu after a while. My linux kernel is 2.6.9.
by the way, i installed the base system using this ISO:
http://penguinppc.org/~eb/files/boot-new-powermac-xfs.iso
which recognized hda as hdc, see this:
# fdisk -l /dev/hdc
/dev/hdc
# type name length base ( size ) system
