Despite what others said, it should really work with every Macintosh

And, it's all already written down in a nice way.[1] Don't read on when
you are happy with this official guide.

The long read: I wanted to share my own experience as well...

Good write-up! Thanks for posting this.

For what it's worth, USB booting on a Power Mac is alwayy trial and
error. Write down what works. I heard that it should be possible to
define a new devalias somehow...

OpenBoot has NVRAMRC, specifically `nvalias` to store a devalias in
NVRAMRC. See e.g [1]. IIRC I've seen a nvramrc environment var in OF,
too, but not sure.
