10.4.2 PCI Device IDs
Each PCI bus, and each device on an individual PCI bus, has a unique ID. For the PP 110/01x,
the bus and device IDs are listed in Table 10-2. The ServerWorks chipset includes two PCI bus
bridges to interface to the 64-bit and 32-bit on-board PCI busses, and these bridges are
identified by the same PCI device ID but with different function codes.
