Hi, I have succeeded in booting an iso for debian http://ftp.uni-augsburg.de/pub/tuxppc/test/Debian-Installer-CD/ and everything works fine except yaboot install (doesb't see any apple_bootstrap partition, partman doesn't allow for prep partition also) and also I don't "see" any scsi disk in open firmware at boot time, the sms console doesn't propose scsi disk in boot order also... Does anybody have an idea of what I might do... Thanks in advance, xavier grave
