HFTaylor12 Posted December 11, 2016 Report Share Posted December 11, 2016 I need to reinstall Leopard on my iBook G4, however I have no dual-layer DVDs to burn my .dmg to. So, I need to boot from USB. I have heard that this has been done before through Open Firmware. How is this done? I might also need to install on my PMG5, so I'd like a method that works with that too. Thanks! Quote Link to post Share on other sites
IlikeTech Posted December 11, 2016 Report Share Posted December 11, 2016 You don't have any dvds? The ones you want are DVD+R Quote Link to post Share on other sites
HFTaylor12 Posted December 11, 2016 Author Report Share Posted December 11, 2016 Only 4.7GB DVDs. The Leopard installer is more than that. So I need to boot from USB. Quote Link to post Share on other sites
IlikeTech Posted December 11, 2016 Report Share Posted December 11, 2016 Oh. I did not realize that it was larger. Quote Link to post Share on other sites
bunnspecial Posted December 11, 2016 Report Share Posted December 11, 2016 Most of the time, you can get away with just typing boot ud:,\\:tbxi in open firmware once your bootable volume plugged in. Quote Link to post Share on other sites
IlikeTech Posted December 11, 2016 Report Share Posted December 11, 2016 That is what I thought as well. Quote Link to post Share on other sites

OK, thanks. My Leopard DMG is still downloading, so I will let you know if it worked or not later today. Quote Link to post Share on other sites
bibilit Posted December 11, 2016 Report Share Posted December 11, 2016 I have done it several times, you only need to format the drive using Disk Utility (IIRC there is an option for Intel and pre-intel material) Â http://lowendmac.com/2014/boot-a-clamshell-ibook-from-usb/ Quote Link to post Share on other sites
Cory5412 Posted December 11, 2016 Report Share Posted December 11, 2016 When you're partitioning the drive in Disk Utility, you need to choose APM as the partition layout type. Just one partition, you can name it whatever you want, and then use the Restore function in Disk Utility to copy the contents of the DMG over to the flash drive.

HFTaylor12 Posted December 12, 2016 Author Report Share Posted December 12, 2016 I am glad to say that bunnspecials Open Firmware command did the trick on my iBook G4. However, when I try with my Power Mac G5, I get the prohibited sign. I was thinking of detaching some USB items on my G5 (like a display that uses USB port for hub) and I will try that later. The installation is currently going smoothly on my iBook G4. Quote Link to post Share on other sites
HFTaylor12 Posted December 12, 2016 Author Report Share Posted December 12, 2016 Tried changing what was attached to the G5, still no luck. Now, if it would help, I have. USB 1TB hard drive. Maybe it would boot from that easier? Quote Link to post Share on other sites
HFTaylor12 Posted December 12, 2016 Author Report Share Posted December 12, 2016 Wait a sec... I can just clone the iBook's hard drive! Quote Link to post Share on other sites
Gorgonops Posted December 12, 2016 Report Share Posted December 12, 2016 If you have Firewire cables lying around I'm personally a huge fan of doing the clone-an-image-of-a-working-one thing to "install" OS X. Target Disk Mode is probably my single most favorite thing about Macs. Quote Link to post Share on other sites

Target Disk Mode is probably my single most favorite thing about Macs. That's what I ended up doing, and now I have Leopard working on my G5! I really like TDM also, I remember quite a while ago I bought a Firewire 400 cable and it was probably one of the best purchases in my life. For just a few bucks, I could install and clone operating systems, as well as recover data, easier than ever before. Quote Link to post Share on other sites
