The PCI_COMMON_CONFIG structure is obsolete. It defines standard PCI configuration information returned by the obsolete HalGetBusData or HalGetBusDataByOffset routine for the input BusDataType PCIConfiguration, assuming the caller-allocated Buffer is of sufficient Length.
DeviceSpecificContains any device-specific initialization information that is available.
Certain members of this structure have read-only values, so attempts to reset them are ignored. These members include the following: VendorID, DeviceID, RevisionID, ProgIf, SubClass, BaseClass, HeaderType, InterruptPin, MinimumGrant, and MaximumLatency.
Other members are provisionally read-only: that is, the system initializes them to their correct values, so drivers can safely treat them as read-only. However, they can be reset if a bus-master driver finds it necessary. These members include the following: CacheLineSize and LatencyTimer.

Drivers call HalAssignSlotResources to configure these values and to get back the bus-relative values passed to other configuration routines.
