IBM RS/6000 43P-240 booting woes...

[Michael Gindonis <Michael.Gindonis@cern.ch>]

Ok, I know this has been asked before...

I've had problems getting both woody and potato CHRP images to 
work on this IBM RS/6000 43P-240

You can see the gory details (system info, environment,
terminal captures of attempted boots) at the following link.

Anyways, I am interested and I am able to spend some time
working on this to get this to get a working kernel. 

I don't know very much about how this work, but would guess that the
CHRP bootloader is having a problem.

Here is the boot log (from  CHRP woody)

</pre>

At this point the machine is frozen, the front panel displays a code of
=F05=

Is there any more information I could provide that would help determine
the problem?

Will cross-compiling powerpc kernels on a x86 machine myself?

Is anyone else working on getting Linux running on a 43P-240 or similar
machine?

Thanks ...
