Install Mac OS X 10.5 Leopard via USB on PowerPC Macs (youtube) And if your iBook is the same, not working with the above USB method then you may need to try the Open Firmware approach to boot from USB: Install OSX 10.5 Leopard on Powerbook G4 (a1138) with a USB drive! WITH 10.5 LEOPARD IMAGE. On PowerPC machines, Tiger is the last version of OS X that supports Classic mode, the built-in virtualizer for Mac OS 9 applications. Using Classic mode on a Power Mac G3 or better, it is still possible to run many applications compiled for the original 680×0-based Macs as far back as the 1980s.
I have a.dmg of 10.4 that I'm trying to write to a USB flash drive so I can boot from it and install Tiger. I don't have access to any system running OS X so I can't use Disk Utility to create an install USB. I've tried TransMac on Windows but I need the partition number to be able to access it through Open Firmware on the PowerBook.

Os X Tiger Upgrade
Here are the instructions to create a live USB of Tiger:
1. Copy the Mac OS X Tiger DVD to an ISO file.
2. Download PearPC (and a GUI, such as PearPC Control Panel) and the 6GB blank disk image (for 8GB drive) or 3GB image (for 4GB drive). Download the trial of TransMac, too.
Download PearPC and 3GB/6GB disk images here.
Download PearPC Control Panel here.
Download TransMac (15-day trial) here.
3. Rename the disk image. For example, 'tigerusb.img'
4. Install Tiger from the ISO using minimal install (uncheck everything but what's required) to tigerusb.img. (Make sure you go into Disk Utility and format the image. Use the volume name 'Tiger USB' for this tutorial)
5. When installation is finished and PearPC restarts, close PearPC when the intro video ends.
6. Plug in your flash drive and open TransMac.
7. Select your USB drive from the list and right click and choose 'Format with Disk Image...'
8. Select 'tigerusb.img' and let it copy to the drive.
9. The bootable drive has been created! Plug it into a PowerPC Mac, hold down Option while turning it on, and select 'Tiger USB'.
10. Configure it like you would as if OS X was on the hard drive.
11. Enjoy your Tiger live USB drive!
This tutorial is for Macs that don't officially support booting OS X off of USB. I use this method because directly installing from the DVD to the USB drive does not work.
