That worked perfectly with my Late Power Mac G5, but it would not work with my older 2. If you have more than one bootable device, type devalias at the prompt, hit Return , and you will see a lengthy list of devices like this. That was a bit of a rabbit trail for me. But that only worked on one of my Power Mac G5s.
The other three I tried simply would not boot from the flash drive.

This was an exercise in frustration! Once I saw that Lubuntu ran decently on my ancient Power Mac G5 Dual, I knew that I wanted to install it on a hard drive so it would boot more quickly and allow me to add more software. I really appreciate the concise, thorough, helpful explanations of what each choice means.
Ubuntu knows that we are interested in making informed decisions and that it needs to educate us through the process.

Or so it seemed. Then it wanted to upgrade from How can I remove Okay, I should have just started with the Lubuntu I wanted you to understand the frustration of trying to do things with a USB flash drive before telling you to bite the bullet and burn a DVD-R disk with the distro of your choosing.
Introduction
You can burn a CD-R, but that usually means trimming the Linux distro to fit on a disc. Booting from the DVD-R was a breeze after all the frustration I had to deal with creating a bootable flash drive and then actually booting from it. I wiped the 80 GB drive in a 2. I ended up with a very nice, friendly, functional Linux machine that lets me run the latest version of Firefox on a Power Mac that was left behind with Mac OS X With four cores running at 2. This is lustworthy hardware, although not especially practical in terms of the current it draws.
Dual-processor and dual-core Power Mac G5s are competent performers, and the faster dual-processor Power Mac G4 machines are solid workhorses as well with decent amounts of power.

There is a whole learning curve going to a different operating system and using primarily free open source software that may have the power of commercial apps — but you need to figure out how to access it. But if you want to set up a machine with an up-to-date operating system and browser that can be used more like a Chromebook than a Mac, Linux could be for you.
Firefox is a staple in the Linux world, and the latest version is fast with a reduced memory footprint. I can run it on my Power Mac G5 Dual nicely. For the sake of brevity, this method assumes that development system's hard drive is also the boot drive containing Mac OS.
[ubuntu_mate] Booting from USB on PowerMac G5 through OpenFirmware
In this example, the boot drive is easily identified if the node has a device alias. This limits the need to identify the hard drive in the device tree and type lengthy node names to access the hard drive. Creating and editing Open Firmware code, as it applies to this method, is accomplished in the Mac OS environment, using any text editor or word processor that will save files in a standard text format i. Code can be written, using the text editor, as it would be entered in the Open Firmware environment -- with one exception.
Although the code in Example 1 meets the criteria for Open Firmware FORTH code, it will immediately run once when booted and has very limited ability for modification if any in the Open Firmware environment. Another approach that lends itself to fewer transitions between editing cycles in the OS and testing cycles in Open Firmware would be to use colon definitions for functions in the code file.
In Example 2, the code will load but not run immediately when booted in Open Firmware. Instead, the colon definitions will be added to the dictionary and can be called as needed in the OF environment.
Some level of editing can now be maintained in Open Firmware by redefining one or all of the colon definitions. The SimpleText application saves the file as a standard text file by default. Other word processors may require you to choose a "text" option under a "Save as It is an obvious but important step to provide a memorable name for the file when saving the file.
Providing a simple and memorable name for the file makes it easier to locate in Open Firmware. It can save some time and typing in the Open Firmware environment if the file is saved at the root level on the primary or boot hard drive. Remember, the desktop is not the root level.
Saving to the root hard drive or a folder on the root hard drive will make the search and path to the file simpler. For these examples, it is also important choose a hard drive in the "Startup Disk" control panel with in MacOS prior to entry into Open Firmware. This ensures that there is a known boot-device in Open Firmware.

Open Firmware will display a message similar to this: Apple PowerMac2,1 1. Since Open Firmware was designed to be platform independent, it is implemented in Forth a simple stack-based language and compiled to bytecodes rather than native machine instructions.
The firmware contains a byte code interpreter. Unlike the BIOS, Open Firmware provides the user with a command-line processor from which one can edit system configuration parameters, such as reduce the amount of physical memory, debug the system, or even start a telnet server so that you can interact with the firmware and boot process from a remote machine via an ethernet connection. Before booting the operating system, the Open Firmware generates a device tree by probing components on the main board and expansion devices.

Like the PC BIOS, Open Firmware contains device drivers that the boot process in the firmware can use to access the disk, keyboard, monitor, and network. However, these drivers are all implemented in FCode, the Forth bytecode system. Also like the BIOS, these drivers are used only during the boot process. The operating system itself has its own native runtime drivers. By default, Open Firmware loads a file from the system partition. Logged Please don't PM about things that are not private.
