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