Best guess is the DVD is machine specific.

Is the Leopard disk retail or did it come with a machine

retail yes..

is there a way around this

No, Leopard is for an INTEL machine not PPC

Try this

1.) Place the 10.5 Install disk in your drive. 2.) Restart your Mac (don't use on the installer on the disk) 3.) After the chime, hold down COMMAND+OPTION+O+F until you see a light gray screen with black text 4.) let go of the keys and type in the following commands EXACTLY as shown, and hit the RETURN key after each line (you will see an "ok" confirming what you typed was correct):

dev /cpus/PowerPC,G4@0 d# 867000000 encode-int " clock-frequency" property d# 867000000 encode-int " min-clock-frequency" property d# 867000000 encode-int " max-clock-frequency" property multi-boot

Select Leopard Install DVD
