Amazingly enough, despite the machine being as old as it is and having survived two moves, I actually found the original media kit w/o a problem. Unfortunately, the CD fails to boot up all the way. It starts loading up something (little Mac Classic logo in the middle of the screen w/some chips and tools around it), but then dumps me to open firmware, where (3x now) I get the following: DEFAULT CATCH!, code=300 at %SRR0: 0073cf88 %SRR1: 00003030 Oh, and the 3rd time I encountered this was after pulling all the memory, blowing out the slots and putting the memory back in, rotated and firmly seated. Suck. Just found http://pyropus.ca/software/memtester/ and will see if that builds/runs/does something useful under ppc32 linux or os x... There's also a non-free (but fairly cheap at $1.39) memtest os x at http://memtestosx.org/. -- Jarod Wilson jwilson@xxxxxxxxxx -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
