Hi, I'm actually having more or less the same problem with my Powerbook G4 Aluminum. I am using the image from https://cdimage.debian.org/cdimage/ports/snapshots/2022-03-18/non-free/ , which I burnt on a USB stick with "dd if=./debian-11.0.0-powerpc-NETINST-1.iso of=/dev/sdg bs=1M" When I boot the machine while holding "option", the USB stick is not found. If I try to boot from Open Firmware, I try "boot usb1/disk@1:,\\grub.img" and the error after quite a long pause is "can't OPEN: usb1/disk@1:,\\grub.img Can't open device or file" Of course I can't rule out the possibility that I'm using Open Firmware wrong, after some searches of this list and on the Internet I didn't specifically find a description of the boot line and I'm really not an OF wizard. But there appears to be a drive at /usb@1b/disk@1 and usb1 seems to be aliased to that usb@1b so I think I did it right. Any ideas that I could try next? Thanks! Sam
