1. Device numbers 0-15 represent devices actually on the compatibility PCI bus.
2. Shaded columns are defined for future PCIset compatibility.
3. This is the compatibility PCI bus.
4. Bus #0/Device # 31 is used (along with a Function Number of all 1’s and a
Register Number of all 0’s) to generate a PCI Special Cycle. Therefore Bus
#0/Device #31 is never mapped to a device.
