Hi! I recently installed Leopard on my G4 MDD 1.2 Ghz desktop. The machine booted fine after installation, so I proceeded to do the software update. It's when I restarted the machine, I found this interesting problem... Upon reboot, there was this flashing graphic on the screen. It's a picture of the world. Yes, you heard me right: A flashing full-color graphic of the world. The system does not boot into OSX, however. Thinking that this could indicate that (maybe) my Mac was trying to boot off a network, I restarted and held down the "Option" key. That led me the familiar menu where you select you boot drive(s). I selected my start up disk -- the only bootable drive I have on this system -- and I still got to the flashing world. I put the machine in firewire mode and re-installed Leopard from my Macbook Pro. (I could not get the Superdrive to open.) This time I did a complete disk erase and re-install. I restarted the machine without doing a software update, however, I still find I'm running into this flashing graphic of the world. I can't recall if anyone knows what this means on any of the boards I've viewed. Does anyone know what's going on? Thanks!
