Hello all, In response to the booting G4 from USB...
I booted my iBook G4 (A1134 2005 model with 1,42 GHz cpu and 1GB DDR) with the string : > boot usb0/disk@1:2,\\yaboot Going straight into the second partition on the USB, where all the boot information is stored. Some use the third partition (replace the 2 with a 3 in the command), however; the third partition contains the live boot. You want the second partition to get the command-line environment. Next I started the install with ‘install32’ and loaded Linux onto my hard disk. After finishing, I made the yaboot load with flags: radeon.modeset=0 radeon.agpmode=-1 radeonfb=1024x768-32 Since my iBook G4 has an old Radeon 9600 GPU in it. Hence the flags. I don’t know how this would translate to loading GRUB and booting Linux on G4’s, but I thought this might be of considerable help.
