the information is correct.
The M8190-BF board I have supports:
(a) PMI memory placed ABOVE the CPU
(b) Non-PMI memory placed BELOW the CPU (I never
attempted to place non-PMI memory ABOVE the
(c) When the PMI memory was placed into the backplane
BELOW the CPU, then the memory would act as
normal non-PMI memory.
Under RT-11, the command:
will conclude that the following CPU is present:
So other than when PMI memory is placed BELOW the CPU
as in (c) and it therefore takes longer to access the memory, I don't
think the question of PMI memory will really make any difference.
