See: http://lists.debian.org/4FDD55CC.7020403@physics.harvard.edu Or try to boot the installer form an USB stick directly. It is not quite straightforward how to do it, but try this: Copy .iso to a USB memory stick using dd. sudo dd if=debian-powerpc-netinst.iso of=/dev/sd[x] Unplug all USB devices and hubs, except the keyboard and mouse. Plug the USB memory stick directly into the machine. Restart the machine while holding option+command+o+f keys. On the Open Firmware prompt type: boot usb0/disk:,\install\yaboot if it does not work, one of these should: boot usb1/disk:,\install\yaboot boot usb2/disk:,\install\yaboot boot usb-1a/disk:,\install\yaboot boot usb-1b/disk:,\install\yaboot boot usb-1c/disk:,\install\yaboot boot usb-2a/disk:,\install\yaboot boot usb-2b/disk:,\install\yaboot boot usb-2c/disk:,\install\yaboot On some machines usb device aliases can be different. To get hints where the USB device is and which alias could be the right one, type: devalias and dev / ls
