Is this the same as "PPC PReP Boot"? No, it is only needed on PowerMacs, but you have a PReP machine, so it should not complain with PPC PReP Boot. It seems hw-detect or yaboot-installer are at fault. Can you issue on the shell "archdetect", "cat /proc/cpuinfo", and post the results? Thanks, -- .''`.
