How did you get your Mac Book Pro partitioned with APM for Leopard in order to get it moved over to your PPC Mac?  I assumed you must have partitioned it with APM right?

As I understand it, Intel Macs (EFI) will boot from both APM and GUID partition maps and PPC (Open Firmware) can only boot from APM. I have tried to install the Leopard DVD onto Intel Macs and force the installer to allow me to put Leopard on an APM disk, but it refuses (Apple is sending a signal I think - they wanna make APM go bye-bye).

What makes the process trickier is the fact that Intel (EFI) Macs can boot from FireWire and USB, but the older PPC (OF) Macs can only boot from FireWire. Take it a step further and you will discover that the Leopard DVD is a dual-layer DVD and isn't available on CD ROMs, which causes problems with older Mac optical drives (I have some eMacs that refuse to boot or even mount the Leopard DVD). I have a work around for this gotcha. I bought a Plextor external dual-layer DVD burner on newegg.com (with both USB 2 & FireWire 400 I/O). Works on every combination of Mac. I very rarely every have to use it for booting/installing an OS, but when you need it you really need it. Never hurts to have a portable burner too. Dual-layer disks are handy sometimes.

Anyway, just curious how you did it. I'm lucky and don't have many legacy Macs here, but occasionally I unearth one.


BTW: Will Leopard's NetBoot server boot PPC and Intel Macs from the same NetBoot image?
