#Boot from USB with the following
sudo dd if=[enter path of .iso here no braces] of=[enter disk identifier here, e.g., /dev/disk5 here]
#In order to know which disk identifier to use, please run:
diskutil list
#In order to format the volume, please run:
diskutil eraseDisk [JHFS+ or FAT32, etc here] [Name of new partition] [disk identifier, i.e., /dev/disk5]
#In order to run the “dd” command which will allow you to make a bootable USB, you need to unmount first so run:
diskutil unmountDisk [disk identifier]
#Now, we need to copy the .iso over to make it bottable … here is an example from PPC for Ubuntu:
sudo dd if=/Volumes/Cave/Users/axes/Desktop/lubuntu-14.04.1-alternate-powerpc.iso of=/dev/disk5 bs=1m
#Here is an example using Tails installer (this is not PPC, but just shows different usage of dd command):
sudo dd if=/Users/me/tails-i386-1.3.iso of=/dev/rdisk9 bs=16m && sync
#Once the USB stick is ready with the .iso of your choice, now you need to plug it in to the PPC machine and boot from it:
#Power on the device while holding down the command, option, o, and f buttons as this will take you to Open Firmware
#Once in OpenFirmware, you need to probe for USB devices (optional) and then command the firmware to boot from the USB:
probe-usb
To boot the USB device you can usually use one of the following commands (on the author's ibook usb0 is the port closest to the front, usb1 is towards the back):
boot usb0/disk@1:2,\\yaboot boot usb1/disk@1:2,\\yaboot
#boot usb2 etc., etc.
#This will now boot from the USB and take you to the Yaboot bootloader by default - once there, commands differ for each .iso
#For MintPPC, you are using a mini-ISO only, and so you enter:
install url=mintppc.org
#for Lubuntu text installer (full .iso but alternate text version) you use:
install
#For Ubuntu mini ISO, for G3 and G4, you use:
cli
#and
cli-expert
#For Ubuntu mini ISO, for 64bit G5, you use:
cli64
#and
cli64-expert
