   RS/6000 systems *may* have many IOU (input/output) or XIO (extended   
   input/output) modules with their own IOCC (I/O channel control unit), each   
   controlling up to 8 Micro Channel slots.   
   See SA23-2647-00 POWERstation and POWERserver - Hardware Technical Information   
   - General Architectures, section 1-8, Figure 3 "Fourth Processor Chip Set".

   My guess is that each IOCC has its own NVRAM.
