Thanks, but the internal DVD drive works fine. I successfully install Debian PPC64 on that machine, as well as Sorbet Leopard.
I don't think it's the drive's fault.

4 other things come to mind:
a) the 'ud' alias isn't valid
b) 'ud' points to a wrong device (test with dev /aliases .properties) or so
c) you've got more than 1 usb stick plugged in
d) stick still somehow isn't readable by the OF, maybe your G5 has some very early OF version that doesn't handle FAT32

I know you say you've formatted it on Sonoma... Did you use commandline or Disk Utility? DI *may* do a bad job. You could format the stick in HFS+ instead. OpenFirmware will read that for sure. Run a Terminal on macOS with the stick plugged in. Do a 'diskutil list' and figure out which /dev/disk* is your USB stick. Then do 'diskutil eraseDisk HFS+ USBstick APM /dev/disk*' replacing * with the right number (do check that twice before you hit enter ;) Copy the iso and boot.img to the usb stick and try again.

Btw there's some reference of OpenFirmware commands here https://library.morph.zone/Open_Firmware

Some notes/suggestion about this solution:

1) When you burned the MorphOS installation CD, did the disc work on some other machine? Did the other machine show MorphOS related files directly when you browsed your CD/DVD drive? There should be tens of directories and small files (like the MorphOS.readme file), and no ISO images there (sometimes people get the ISO image file burned on a disc, instead of actual contents).

2) If you did burn the installation CD to a CD disc, try burning it to a DVD disc. CD and DVD mechanisms are separate in the drive, and sometimes it has happened that the CD part doesn't work while the DVD part does work still.

3) Try burning to a disc that is a different brand, for some reason Verbatims never work on my machines :)

I actually never managed to boot form USB drive on my PCIe PMac (it is very picky about the kind of drives, as I read on some older, archived PMac forums).
None of the USB sticks I used worked properly. The only way to update for me is to boot using a DVD. And it always works flawlessly.

Point d). Yep. I tried HFS+ and FAT32 with Disk Util, both with GUID, Apple Partition Map and MBR, as well as on a Win11 PC. Same error each time. There is something about wrong sectors size. You agree that only 2 things should be on the stick, right? morphos.iso and boot.img.

BTW, none of them are mountable in MacOS.

Maybe superfluous to remind. Did you rename the ISO copied to the stick ? Currently, the name of the MorphOS latest iso file (3.18) downloadable from the main site is morphos-3.18.iso ... you've to rename it to morphos.iso to allow working the command you typed in Open Firmware as reported in your post #1.

What I meant is that is it or is it not necessary to copy all the files from the morphos.iso to the USB stick along with those two files (boot.img - PPC64 & morphos.iso)? Because when I burn morphos.iso to a CD, it just extracts and burns them, and you can't add the correct boot.img afterwards nor add the morphos.iso file by itself. Maybe that's why the CD isn't booting, nor bootable... The whole process is not very clear. It's more trial and error.

Thanks

1). I don't have another machine that can read these CD's. I made a few... May I did it wrong... Unfortunately, to me, the instructions are not clear and detailled enough.
On the USB, I tried both ways. All the files were copied to the stick, the boot was replaced with the correct one, and morphos.iso was also added. Nothing worked.

Just burn the iso to the CD with whatever burning tool you have. The CD should be browsable afterward. No rocket science here, that's ISO9660 rockridge thingy afair after all.

If when browsing the CD you see a single file named like the iso, it is a fail, you should see a 'lot of' files and directories.

No need to copy/add/mess with the iso content at all. It should just boot fine on any supported hardware.



Also, if you extract the iso content to some 'smart burning directory' and burn down those files, it won't boot at all. You need to use a tool that is able to write directly the ISO to the CD: a *raw* burn of the ISO is needed.

Dunno if it makes things clearer here.

I did exactly that several times on a windows machine. It is NOT working. MacOS cannot burn this .iso file.

I've burned multiple MorphOS ISO's from MacOS ( Sonoma ) and they work perfectly in my G5 machines.

And you burned it from this kind of window on Windows?

Is your MorphOS ISO image file size exactly 435 269 632 bytes?

And the G5 is still not booting from it.

Hmh.. and you have tried both Alt/Option key boot menu that the CD doesn't appear there, and booting from CD from Open Firmware? I don't know then... never had these kind of problems on my about 10 MorphOS compatible computers...

Did'nt read now all of that above, but: There are some firmwares on G5 which cannot read sticks bigger than 4GB!! Not only partitions - the whole stick must not have more than 4GB. And even than, some sticks are'nt readable (seems to depend of "firmware" in the stick itself....)

If you have a smaller one, just format it FAT and copy something on it (just for test). Then plug it to the front-port of the G5 and turn him on.
In OpenFirmware-Console type:
>devalias

Now device ud should be listed with following path: ht@0/f2000000/pci@4/usb@b,1/disk@1
(If only one massstore USB-device is plugged in!!). If your path is different, please post it. This will be strange, because path is hardcoded to usb-port.

If it occours then type:

dir ud:\

-> the content of ud should be listed!


If this does'nt work, your stick may be "incompatible" - some sticks won't work, anyway the have 4GB or less..... you have to try another one, or better a USB-HD. To my experience HDs work in most cases and does'nt depend on over-all size (but first partition <4GB).

If you don't see ud-device in devalias-list, then it's a bit more tricky, but there is also a way to acces a usb-port.
Please post your firmware-version
If everything above works, we can try to prepare stick for booting.

If nothing works, there is a way to start boot.img via tftp-server (running on a PC):

Copy boot.img to your tftp-server. Format a USB-Stick with SFS (FAT should also work) and copy the content of MorphOS-ISO (not the iso itself) on it and plug it to G5.

boot in OF on MAC:

> enet:<IP of server>, boot.img BD=USB

Boot.img will be loaded and kernel starts. MorphOS includes a USB-stack and is able to boot the rest from every usb-device (finds the right USB automaticaly).

To boot from the CD, I needed to press and hold "ALT C" at boot, not just C.

"C" should boot from CD but isn't 100% reliable.

"ALT" will get you into the boot menu, from which selecting the CD works pretty much always.

"ALT C" doing anything other than 1 of the 2 would be news for me.
