The code for temporarily changing some Open Firmware device tree strings is about right, so it really should work. You can check with the “.properties” command: > dev /cpus/PowerPC,G4@0 .properties > d# 867000000 encode-int " clock-frequency" property .properties > boot cd:,\\:tbxi (BTW, “mac-boot” plus immediately holding the Option key after hitting enter— you ought to be fast—will give the boot selection screen.) Try a normal boot—without the Open Firmware hack—and see if that works. It should boot normally, you’ll see the language selection of the Leopard installer and then it will tell you that “this Mac is not supported” (or similar). If that works, your installation media (aka CD or DVD) is alright. Then there’s something else causing this message… Did you try booting the DVD without the hack? Does it boot normally? (hold the “C” key to boot from CD/DVD) Cheers, Andreas aka Mac User #330250 -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
