I have been trying to install Ubuntu 12.04 PowerPC on an iBook G4. The install appears to go fine but on booting into the new OS the screen gets to the Splash screen where is says Ubuntu 12.04 with four dots below but it also give an error message [ 25.979435] b43-phy0 ERROR: Firmware file "b43/ucode5.fw" not found.
It says to go to a website and download the firmware. Unfortunately the screen and all of the keys are locked. Reboot doesn't help. Any help would be appreciated.
