Trying to boot on powermac G4, having this problem. I managed to boot
earlier, but after having installed openbsd it no longer works.

A little more info:

-I tried FreeBSD ppc image for version 13.1, 13.0 and 14.0.

-I tried memstick, DVD, Disc and bootonly images

-The machine has 2 IDE HDDs 20GB each and 2x256MB RAM to a total of
512MB.

I fear that it is hardware failure somewhere, because nothing else did
boot either, but I am not familiar with this old firmware

If Mac OS 9 / X boots hardware is fine...

Mac OS isn't installed

> I fear that it is hardware failure somewhere,

It booted FreeBSD before you installed OpenBSD, so what have you done
to reinstall FreeBSD?

Also/alternatively: /r/openbsd

I can't reinstall freebsd now. Openbsd was fine, but I prefer FreeBSD
so I want to boot the installer again, but it doesn't start with the
following error message.

Try to wipe drives and repeat install. I guess some Linux
distribution can be helpful for running dd from it.

Try zapping the PRAM (or whatever it is, technically, for that class
of Mac).

Or, if you can get any FreeBSD to boot, [efibootmgr\(8\)](https://www.
freebsd.org/cgi/man.cgi?query=efibootmgr&sektion=8&manpath=FreeBSD)
might help.

Update: After RTFMing a little I found what I looked for in the
handbook.

The command needed was `boot usb1/disk@1:,\ppc\loader usb1/disk@1:0`
