Heya - On the link below, is one to come to the conclusion it will run on a Ultra Sparc? http://docs.fedoraproject.org/install-guide/f7/en_US/sn-which-arch.html "Apple Macintosh G3, G4, G5, PowerBook, and other non-Intel models" One might think that this indeed could include an Ultra Sparc. -- Best regards, Chris Registerd Linux user number 448639
