PrPMC800/800ET Processor PMC Module Installation and Use (PrPMC800A/IH5)
15
The PrPMC800/800ET
module can function as a system controller (monarch mode) for the host
board or as a slave processor (non-monarch) PMC, depending on the state of the MONARCH#
signal from the PMC connector. When configured as the monarch, the PrPMC800/800ET’s
PPCBug enumerates the PCI bus as well as monitor and service the four PCI interrupts.
