Hi Ami,
Thanks for the reply. Yes I have the manual. I guess I need to be a
little more specific. I usually don't get down to this level of the
hardware. It usually just works for me.
I have all the explinations etc.. of each vector, but in my memory, I
can't figure out how to map 0x0000_0700 to one of the SPR's. I think
that's what I want to know. :)
