Could someone please point me to same? I've found references to a beta boot.iso, but that seems no longer available, and I've found only empty "isos" directories, e.g.: http://mirror.centos.org/centos-4/4.2/isos/ppc/ I'm not the only one to be looking: http://www.centos.org/modules/newbb/viewtopic.php?topic_id=2209 Thanks
