[dogbeans]

hey i used software update 10.5.8 on my ideneb 10.5.7 install. now i get waiting for root device. I was wondering if there is a solution for that. ??install some kexts manually or something??? Also is there a way to retrieve some files of that install. I left all my pictures on it and dont have any backups!!!!!!!

Thanks
