I'll investigate how to setup a DHCP and TFTP server on > my OS X (Yosemite) and how to boot iBook from network. Here's a guide for Ubuntu, it might still be helpful to you if you can use dnsmasq and (a normal) tftpd. https://help.ubuntu.com/community/Installation/Netboot Booting from the network is rather easy, and it is a nice thing to have set up in case you might need it in a situation like this. Both of my desktop machines at home are set up to boot from each other in case the root disk fails on one of them, and it is really helpful when I need to boot from something other than the normal root disk. Here is a guide on how to boot an iBook G4 from USB: http://ben-collins.blogspot.no/2010/08/booting-your-ibook-g4-from-usb-stick.html > > 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. :) Keep going :) Good luck, Petter -- "I'm ionized" "Are you sure?" "I'm positive."
