[GUIDE] NEW Method: Booting from USB on PowerPC Macs

[ediflorianus]

I'm getting stuck at loading from open firmware after selecting the usb drive probe-usb usb2 /disk:1,\\:tbxi it says cant open than hangs. True I have a 64gb flash drive. I can't find anything older in local-stores and I won't pay big amount for shipping a flashdrive.... the dvd sees the drive fin in disk utility 10.5, I can even install the osx there,but it just won't boot from it, however info in disk utility says bootable....very confusing

I would try to avoid new USB drives in general with older hardware, especially any that large. I'd try to go with a 16GB capacity. This problem happened with some USB drives with i.e. a PS2 because the USB1.1 support in the USB drive wasn't really compatible with USB 1.1. I know, not the same thing, but maybe it could help here.

Also kind of unrelated, but Wallmart sells 16GB flash drives for literally $3, I have a ton of them. And they work even with a PS2 (which is extremely picky as mentioned above). I would try one of those.

As someone who has never, not once gotten a PowerPC Mac to boot anything from USB, I am excited to give this a try. Thanks OP for recognizing this issue is real (there was much debate on these forums years ago about if it was even possible).
