In the following command, should be replaced by what you found in Step 5, also every character is important (this includes colon, forward slash, etc.). Make sure your USB key holds a file called BootX with the tbxi attribute by listing the directory.Type dev / ls and try to find something like next to an entry named USB (in my case Type DEVALIAS in the command prompt and locate the short name of the USB entry you just found using dev / ls (in my case usb0).Then you boot in the PowerBook OpenFirmware (the bootstrap that loads before Mac OS X) by pressing the Apple+ Alt+ O+ F keys at the same time right after you switch on the machine (before the chime sound). Reproducing them here for clarity, formatting and reference: Once in OpenFirmware enter this command: boot If that somehow doesn’t work, you might be designating the incorrect usb/ path so try this one with 0 for usb: boot The machine should reboot and you should be now booting off of the USB.Īnd if none of that seems to work, the later page referenced above seems to be a more succinct answer starting from item 4 in the list of instructions.Boot in the PowerBook OpenFirmware (the bootstrap that loads before Mac OS X) by pressing the Apple+ Alt+ O+ F keys at the same time right after you switch on the machine (before the chime sound).And it boils down to following these two steps after creating the bootable USB flash drive: So that alone won’t work, but advice in this answer as well as on this page will help. And when that is done, you will have a bootable USB flash drive with on it.Īnd with that said, I realized that your PowerBook does not formally allow USB booting. Okay, with disk1s1 unmounted, run the dd command to copy the contents of to the USB flash drive on /dev/disk1s1: sudo dd if="" of="/dev/disk1s1" bs="10240" Now we’re going to unmount the USB flash drive from the command line like this: sudo diskutil umount /dev/disk1s1 Now, with the USB flash drive plugged into the computer run this command to get the filesystem name of the USB device: df -hįor this example, let’s assume the device is named disk1s1. For this example I am downloading the version of the image (which is the version tailored for USB flash drives) and saving it to the ~/Desktop.įirst, let’s open up the Terminal and go to the desktop like this: cd ~/Desktop And why not clear that up here?įirst, download the appropriate Free BSD ISO from here. I am reworking those instructions because there are a few unclear/out-of-date things that should be ironed out. If you can’t use UNETbootin because your system is out of date, instead of using UNETbootin-or similar packaged “Make a bootable USB” tools-you can create a bootable USB flash drive right from the command line in Terminal as explained here.
