    I'm trying to boot my Power Mac G5 to my installation media through an external USB DVD drive. How do I do this? I've booted to USB drives on my Power Mac G4, so I think it should be possible on my Power Mac G5.

    This is what my USB devices look like in Open Firmware.

    The USB drive will be the usb@b/disk@2 device. So it should then be the same as your G4s.

    Get the USB device alias with `devalias` e.g. "usb0", then boot with something like;

    `boot usb0/disk@2,\\:tbxi`

    Most Mac boot discs will load from partition 3, so "usb0/disk@2:3"

    Play around with a few variations until you get it. OF feels like trial and error most of the time :)

    Thanks for the response. I didn't end up needing to do this, but I'll keep your tips for future reference.
