Intel Nitro Card - i960 processor on the card. The SMP debugging involved the use of a bus analyser since this card had a piggish memory bus footprint (i960 processors do not have an IO address space, so everything is memory mapped. The big weakness of early I2O stuff was that the I960 running off on the boards had access to the memory bus of these early systems. Performace problems that were related to passing messages to the embedded OS running on the i960 on the Nitro Card, and it "missing" messages when two processors were talking to it at once.
oink, oink, oink!
