Why does PREP reset at this vector? Is it architected to that? Does 601 reset
to that offset?
I don't know why PReP reset here. As I said in the hreset_vector patch,
even if the core manual says that hreset is at 0xfff00100, the value is
in fact board specific. OpenHackWare expects 0xfffffffc as reset
address.
Do you have 601e or 601 specs handy? Maybe they have a different reset
vector.
Maybe OHW is also just wrong ;).
