Installation problem (root image not found)

Hi, I have strange problem with SuSE 7.1 PPC. When I try to upgrade already installed 7.0 from 7.1 CD, I am always get message "valid root image not found". I have checked path to /suse/images/root, the root file is there. CD-ROM is spinning, and CD1 is mounted (after all, I am started Mac from this CD). I have choosen before install/update from the main menu: settings --> Debug (expert) --> force rootimage It did not helped either. Then I copied suseboot on my HFS /macboot partition, started from /macboot/, but the problem still exists. I did the same with 7.0, and everything was OK. What could be wrong? PS. I am currently downloading 7.1 ReiserFS boot ISO, may it will work. Thanks in advance Andrei
