Some say it is impossible to boot Powermacs from USB, others says: only PowermacG5 from 7,3 Revision are able to boot from USB and the third party says: every Powermac is bootable.</p> <p>And because I own this late and great Powermac G5 11,2 and I don&rsquo;t want to always burn a CD/DVD everytime I try a new Linux or something else out, I invesitagted a little bit further: the third statement is correct: <em>every Powermac can boot from USB.</em></p> https://apfelhammer.de/posts/using-openfirmware-on-powermacs/ Sat, 11 Oct 2025 00:00:00 +0000 https://apfelhammer.de/posts/using-openfirmware-on-powermacs/ <p>There is always the discussion around if the Powermacs are able to boot from USB or not and I can say: every Powermac G5 is able to boot from USB Thumbdrive. So it is quite easy to dd an ISO of Linux or Leopard to an USB-Drive and boot-up the Powermac G5 with it. But also older Macs. Older Roms. Older Edlers.</p> <!-- raw HTML omitted --> <h3 id="accessing-open-firmware">Accessing Open Firmware</h3> <p><strong>Method I</strong>: At the chime, hold down the Option key.
