Delete the "console=tty0", so you end up with:

 Linux/PPC load: console=ttyS0,9600 root=/dev/ram

and try again!

It should never ask the console question again unless you change the
config (plug in a mouse for example), unless your nvram battery is a
bit flat of course!

This seems to be the case. But it really simplifies things, as I've never
been able to warm-boot anything ;-) Only a cold boot helps. Maybe Daniel
should remove the battery to reset things completely?

Anyway, without your site, Leigh, I would still have a big doorstop only,
thanks again,

No problem.  The amazing thing is, once you actually get them running,
RS/6000's run Linux really reliably.  It's getting them booting that's
the problem :-/
