Base address of the memory that can be prefetched by the bus. The upper 12 bits of this property specify the address bits, AD[31::20], of a 32-bit memory address. Each of the remaining 20 bits of the address are assumed to be 0.
uint16 MemoryLimit
End address of the memory supported by the bus. The upper 12 bits of this property specify the address bits, AD[31::20], of a 32-bit memory address. Each of the remaining 20 bits of the address are assumed to be 1.

uint8 BusNumber
The bus number where this PCI device resides.
string SystemCreationClassName
The CreationClassName of the scoping system.
uint16 MemoryBase
Base address of the memory supported by the bus. The upper 12 bits of this property specify the address bits, AD[31::20], of a 32-bit memory address. Each of the remaining 20 bits of the address are assumed to be 0.
uint8 IOBase

uint16 IOBaseUpper16
Upper 16 bits of the supported I/O base address when 32-bit I/O addressing is used. The lower 16 bits are assumed to be 0.
uint16[] Capabilities
An array of integers that indicates controller capabilities. Information such as “Supports 66MHz” (value=2) is specified in this property. The data in the Capabilities array is gathered from the PCI Status Register and the PCI Capabilities List as defined in the PCI Specification.
ValueMap Values 0 Unknown 1 Other 2 Supports 66MHz 3 Supports User Definable Features 4 Supports Fast Back-to-Back Transactions 5 PCI-X Capable 6 PCI Power Management Supported 7 Message Signaled Interrupts Supported 8 Parity Error Recovery Capable 9 AGP Supported 10 Vital Product Data Supported 11 Provides Slot Identification 12 Hot Swap Supported 13 Supports PCIe 14 Supports PCIe Gen 2 15 Supports PCIe Gen 3 16..32767 DMTF Reserved 32768..65535 Vendor Reserved
uint8 SecondaryLatencyTimer
The timeslice for the secondary interface when the bridge is acting as an initiator. A 0 value indicates no requirement.
string ElementName
A user-friendly name for the object. This property allows each instance to define a user-friendly name in addition to its key properties, identity data, and description information.
Note that the Name property of ManagedSystemElement is also defined as a user-friendly name. But, it is often subclassed to be a Key. It is not reasonable that the same property can convey both identity and a user-friendly name, without inconsistencies. Where Name exists and is not a Key (such as for instances of LogicalDevice), the same information can be present in both the Name and ElementName properties. Note that if there is an associated instance of CIM_EnabledLogicalElementCapabilities, restrictions on this properties may exist as defined in ElementNameMask and MaxElementNameLen properties defined in that class.
string SubsystemName
Name of the subsystem
uint16 SecondaryStatusRegister
The contents of the SecondaryStatusRegister of the Bridge. For more information on the contents of this register, refer to the PCI-to-PCI Bridge Architecture Specification.
uint8 PrimaryBusNumber
The number of the PCI bus segment to which the primary interface of the bridge is connected.
uint16 IOLimitUpper16
Upper 16 bits of the supported I/O end address when 32-bit I/O addressing is used. The lower 16 bits are each assumed to be 1.
string DeviceID
An address or other identifying information used to uniquely name the LogicalDevice.
string PCIDeviceName
Name of the device
uint8 CacheLineSize
Specifies the system cache line size in doubleword increments (for example, a 486-based system would store the value 04h, indicating a cache line size of four doublewords.
uint16 PrefetchMemoryLimit
End address of the memory that can be prefetched by the bus. The upper 12 bits of this property specify the address bits, AD[31::20], of a 32-bit memory address. Each of the remaining 20 bits of the address are assumed to be 1.
string VendorName
Name of the vendor
uint16 PCIDeviceID
Register that contains a value assigned by the device manufacturer used to identify the type of device.
string InstanceID
InstanceID is an optional property that may be used to opaquely and uniquely identify an instance of this class within the scope of the instantiating Namespace. Various subclasses of this class may override this property to make it required, or a key. Such subclasses may also modify the preferred algorithms for ensuring uniqueness that are defined below.
To ensure uniqueness within the NameSpace, the value of InstanceID should be constructed using the following “preferred” algorithm:
<OrgID>:<LocalID>
Where <OrgID> and <LocalID> are separated by a colon (:), and where <OrgID> must include a copyrighted, trademarked, or otherwise unique name that is owned by the business entity that is creating or defining the InstanceID or that is a registered ID assigned to the business entity by a recognized global authority. (This requirement is similar to the <Schema Name>_<Class Name> structure of Schema class names.) In addition, to ensure uniqueness, <OrgID> must not contain a colon (:). When using this algorithm, the first colon to appear in InstanceID must appear between <OrgID> and <LocalID>.
<LocalID> is chosen by the business entity and should not be reused to identify different underlying (real-world) elements. If not null and the above “preferred” algorithm is not used, the defining entity must assure that the resulting InstanceID is not reused across any InstanceIDs produced by this or other providers for the NameSpace of this instance.
If not set to null for DMTF-defined instances, the “preferred” algorithm must be used with the <OrgID> set to CIM.
uint16 DeviceSelectTiming
The slowest device-select timing for a target device.
ValueMap Values 0 Unknown 1 Other 2 Fast 3 Medium 4 Slow 5 Reserved
uint32 PrefetchLimitUpper32
Upper 32 bits of the supported prefetch end address when 64-bit addressing is used. The lower 32 bits are each assumed to be 1.
string SystemName
The System Name of the scoping system.
uint16 SecondaryBusDeviceSelectTiming
The slowest device-select timing for a target device on the secondary bus.
ValueMap Values 0 Unknown 1 Other 2 Fast 3 Medium 4 Slow 5 DMTF Reserved
string Description
The Description property provides a textual description of the object.
uint8 RevisionID
Register that contains a value assigned by the device manufacturer used to identify the revision number of the device.
uint16 SubsystemVendorID
Subsystem vendor ID. ID information is reported from a PCIDevice through protocol-specific requests. The correct place in the CIM Schema for this information is in CIM_Physical Element (the Manufacturer property) for hardware, and CIM_Product (the Vendor property) if the information is related to Product acquisition. This data is also reported here, because it is part of the standard output from the Device and is an optimization.
uint8 FunctionNumber
The function number for this PCI device.
string Name
The Name property defines the label by which the object is known. When subclassed, the Name property can be overridden to be a Key property.
The Caption property is a short textual description (one- line string) of the object.
uint32 ExpansionROMBaseAddress
Doubleword Expansion ROM-base memory address.
uint8 ClassCode
Register of 8 bits that identifies the basic function of the PCI device. This property is only the upper byte (offset 0Bh) of the 3-byte ClassCode field. Note that the ValueMap array of the property specifies the decimal representation of this information.
ValueMap Values 0 Pre 2.0 1 Mass Storage 2 Network 3 Display 4 Multimedia 5 Memory 6 Bridge 7 Simple Communications 8 Base Peripheral 9 Input 10 Docking Station 11 Processor 12 Serial Bus 13 Wireless 14 Intelligent I/O 15 Satellite Communication 16 Encryption/Decryption 17 Data Acquisition and Signal Processing 18..254 PCI Reserved 255 Other
uint8 SubordinateBusNumber
The number of the highest numbered bus that exists behind the bridge.
string CreationClassName
CreationClassName indicates the name of the class or the subclass used in the creation of an instance. When used with the other key properties of this class, this property allows all instances of this class and its subclasses to be uniquely identified.
uint32 PrefetchBaseUpper32
Upper 32 bits of the supported prefetch base address when 64-bit addressing is used. The lower 32 bits are assumed to be 0.
