Can the machine boot from a USB flash drive? Or over the network? One
of these approaches might be easier for you.

I'm trying to find out how to boot form USB. Boot from network also sounds good. I'll investigate how to setup a DHCP and TFTP server on my OS X (Yosemite) and how to boot iBook from network.

Other than that, I'm afraid I can't help you - I know nothing about
yaboot.

I never know about yaboot and Open Firmware when I was using Mac OS X on the iBook. They're all mysterious to me. Still learning. :)

Thanks.
