The first field is the Device ID of the slot. This value may range from zero to 31. The
second field is the Base IRQ Pin for the slot. You can choose from pin A, B, C, or D.
The third field is an Enable Slot. By default, all slots are disabled. One cannot disable a
slot that has a device connected to it.
Differences from Real Hardware
The PCI Bus device differs from other devices in that it is a generic model. We do not
simulate PCI down to a clock-accurate level, so devices do not arbitrate for bus
ownership or insert wait states, for example.
