Hello,

What is the 2z691-****-A number on that Install Disc?

If you don't know the G4, find the Serial# & use it on one of these sites, but don't post the Serial# here...

Leopard 10.5.1 I believe it is the Family Pack retail disk, the product number is: 2Z691-6178-A.

Perhaps your G4 is too old to read DVD Dual-layer Discs?

Leopard requirements/10.5.x...

    *  Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor

minimum system requirements

    * 512MB of memory (I say 1.5GB for PPC at least, 2-3GB minimum for IntelMacs)

    * DVD drive for installation

    * 9GB of available disk space (I say 30GB at least)

Classic/OS9 Apps no longer supported.

There are workarounds if the 867MHz CPU is the only hangup...
