The powerpcspe ISO won't work on a Talos.  I don't even expect that
particular ISO to work at all, given the nature of the architecture.
For Talos, and IBM POWER* in general, you need the powerpc64 ISO.

I don't know if that will solve your problem, given the errors printed
below, but it's at least a first step.
