Notes:
1. Software-defined switches.
2. Optional feature.
3. Some PCI devices do not allow their own IDSEL to be asserted when operating as the PCI host; if so, use this switch to
disable IDSEL. Not applicable for PCI agents.
4. This switch configures the MPMC card into the system controller, a mode which is required for normal PCI use. Disabling is
provided for testing purposes only.
