First off, I have tried and tried again over the years to boot various PowerPC Macs via a USB2 disk. Thankfully, somewhere about the time the iMac G5 with the ambient light sensor (ALS) was released, Apple tweaked their Open Firmware, which allowed us to boot PowerPC Macs from USB2 drives.
I heard you Tom! William Nash: what dvd is that?
And where can I buy it? My mac g5 keeps ejecting the disc.
I even bought a new hard drive and the disc can not be clean installed. Francisco Fuentes: Hello, my friend. I have very weird issues by making a Leopard bootable DVD. Can you help me?
I need it to restore one of these. Arthur Alt: i cant get osx10.5 on my ibook please help! Unknown Prodigy: hey,you think you can make a leopard copy for iMac G4.please?. Please reply back Partha Dey: Hi James, You need to get the disk image of your OS disc and use the software 'Power iso', which is available on windows and is free.
When you open power iso, go to tools and click 'create bootable usb'. The software will restart prompting you to run the software as an admin. Then click 'create bootable usb' again and select your image and your USB which you want to write to. After the USB is created, plug it in your mac, restart, and hold the option key (alt key), and boot from the USB.:-) Jace'sFunkyFace: 36 minutes is quick?

. The BIOS for Apple PowerPCs is Open Firmware. It is the only way to boot the machine from anything but the hard disk or the CDROM. Note: Some older G3 models can access Open Firmware via an external terminal. If you have one of these, you need an external terminal or another PC that can emulate one.
Note: You may want to print this out before you start. To access Open Firmware (OF): Plug in the USB drive before you reboot.
Reboot the machine and between the chime and the first screen, hold down the opt + cmd + o + f keys. You should see the OF prompt. Ok 0 List all the devices on the machine. Write down the ones with usb. Note: This is from my machine. YMMV 0 dev / ls.
