This documents my ( dave josephsen's ) experience installing on a powermac g4 (pci graphics) with the new 9.4 ppc iso

I'll paste from afrayedknots article and make changes where necessary

1. BOOTING THE ISO

• == 1.1. Entering the Openfirmware ==

boot into Open Firmware and tell it in more explicit instructions how to boot : hold :

Command(apple)+Option(alt)+o+f as the computer is booting up.

• == 1.2. Entering Yaboot ==

Once you are in the OpenFirmware, you now want to launch Yaboot, (analogous to "grub"). type at the OF prompt :

boot cd:\\yaboot\\yaboot

The screen turns black and you have a yaboot prompt.

• == 1.3. Launching the kernel ==

Yaboot appears to be unable to read it's config. If you type:

cd:0,/boot/linux

Linux will boot, but will have no rootfs and will kernel panic.

If you wait the 180 seconds for a reboot the yaboot prompt will now read it's configs, and be blue, and the prompt should read something like "To install Source Mage right now just press enter".

do that.

2. THE INSTALLER

I'm currently stuck here because there is still no root. I've tried going to cmdline and doing mount -t iso9660 /dev/cdroms/cdrom0 / but no dice. Bad fs type or filesystem.
