It was always my understanding that the Ultra 2 did a non-optional 4-way
interleaving, since Sun says to add memory in groups of 4 dimms, and
states that the datapath is 576bits in the system handbook.

My Ultra 2 also never listed interleaving in prtconf.  Again I just
assumed this was because it was non-optional.  Anyone know the real
reason?  What was the first Sun box to show interleaving info in prtconf?
