Ubuntu/PPC

See https://wiki.ubuntu.com/PowerPC.

Note: The following has been tested on a Mac iBook G4 (mid 2005)

Ubuntu 10.10 PowerPC

 * https://wiki.ubuntu.com/PowerPCFAQ
 * Ubuntu 10.10 (Maverick Meerkat)

USB device installation

 * Use 'Startup Disk Creator' from the System > Administration menu from an i386/x86-64 Ubuntu installation (as the PowerPC version of Ubuntu doesn't support SYSLINUX, but the install CD contains the yaboot bootloader that is required, and it will be transferred to the USB).
 * Choose the downloaded Ubuntu Desktop 10.10 PPC .iso file or burned CD-ROM as the Source.

Install Yaboot boot loader

 * Read the precautions at this page, Boot PowerPC Macs via USB 2.0 drives
 * Power on while holding four keys down, option+Apple+o+f. This takes you into Openfirmware.
 * Enter devalias at the 0 > prompt (See step 4 in the above reference.)
 * Note the exact usb device addresses.
 * By experimentation, I found that my USB device would boot after setting the boot-device with this command:
 * setenv boot-device /pci@f2000000/usb@1b/disk@1:1,\install\yaboot
 * If the USB disc is not around, the default boot-device will boot your regular Mac installation.
 * Check your setting with this command:
 * printenv boot-device
 * Your system may have different addresses, so it may take a while to discover the proper address.

Dual Boot with Mac OS X Leopard version 10.5

 * Use the Mac install DVD to resize and create partitions (including swap) for Ubuntu
 * Burn the Ubuntu installation CD and install Ubuntu into the new partition by booting the CD-ROM.
 * Use System > Administration > Additional Drivers to install the Broadcom B43 wireless driver.
 * Use Ubuntu Software Center to search for Sugar. Install Sugar, the emulator for the Sugar Desktop Environment, plus dependencies and Activities suitable for Sugar 0.88
