Win32_BaseBoard Class

The Win32_BaseBoard class represents a base board (also known as a motherboard or system board).
Namespace value is root/CIMV2.
WMI Provider value is CIMWin32.


  • Caption
  • The Caption property is a short textual description (one-line string) of the object.

  • ConfigOptions
  • The ConfigOptions property contains strings that describe the configuration of the jumpers and switches located on the base board.
    Examples: JP2: 1-2 Cache Size is 256K, 2-3 Cache Size is 512K, SW1-1: Close to Disable On Board Video

  • 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.

  • Depth
  • The depth of the physical package in inches.

  • Description
  • The Description property provides a textual description of the object.

  • Height
  • The height of the physical package in inches.

  • HostingBoard
  • Boolean indicating that this card is a motherboard or, more generically, a baseboard in a chassis.

  • HotSwappable
  • A physical package can be hot swapped if it is possible to replace the element with a physically different but equivalent one while the containing package has power applied to it (i.e., is 'on'). For example, a disk drive package inserted using SCA connectors is removable and can be hot swapped. All packages that can be hot swapped are inherently removable and replaceable.

  • InstallDate
  • The InstallDate property is datetime value indicating when the object was installed. A lack of a value does not indicate that the object is not installed.

  • Manufacturer
  • The name of the organization responsible for producing the physical element. This may be the entity from whom the element is purchased, but this is not necessarily true. The latter information is contained in the Vendor property of CIM_Product.

  • Model
  • The name by which the physical element is generally known.

  • 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.

  • OtherIdentifyingInfo
  • OtherIdentifyingInfo captures additional data, beyond asset tag information, that could be used to identify a physical element. One example is bar code data associated with an element that also has an asset tag. Note that if only bar code data is available and is unique/able to be used as an element key, this property would be NULL and the bar code data used as the class key, in the tag property.

  • PartNumber
  • The part number assigned by the organization responsible for producing or manufacturing the physical element.

  • PoweredOn
  • Boolean indicating that the physical element is powered on (TRUE), or is currently off (FALSE).

  • Product
  • The Product property indicates the base board part number defined by the manufacturer.

  • Removable
  • A physical package is removable if it is designed to be taken in and out of the physical container in which it is normally found, without impairing the function of the overall packaging. A package can still be removable if power must be 'off' in order to perform the removal. If power can be 'on' and the package removed, then the element is removable and can be hot swapped. For example, an extra battery in a laptop is removable, as is a disk drive package inserted using SCA connectors. However, the latter can be hot swapped. A laptop's display is not removable, nor is a non-redundant power supply. Removing these components would impact the function of the overall packaging or is impossible due to the tight integration of the package.

  • Replaceable
  • A physical package is replaceable if it is possible to replace (FRU or upgrade) the element with a physically different one. For example, some computer systems allow the main processor chip to be upgraded to one of a higher clock rating. In this case, the processor is said to be replaceable . Another example is a power supply package mounted on sliding rails. All removable packages are inherently replaceable .

  • RequirementsDescription
  • A free-form string describing the way(s) in which this card is physically unique from other cards. This property only has meaning when the corresponding boolean property, SpecialRequirements, is set to TRUE.

  • RequiresDaughterBoard
  • Boolean indicating that at least one daughterboard or auxiliary card is required in order to function properly.

  • SerialNumber
  • A manufacturer-allocated number used to identify the PhysicalElement.

  • SKU
  • The stock keeping unit number for this physical element.

  • SlotLayout
  • SlotLayout is a free-form string that describes the slot positioning, typical usage, restrictions, individual slot spacings or any other pertinent information for the slots on a card.

  • SpecialRequirements
  • Boolean indicating that this card is physically unique from other cards of the same type and therefore requires a special slot. For example, a double-wide card requires two slots. Another example is where a certain card may be used for the same general function as other cards but requires a special slot (e.g., extra long), whereas the other cards can be placed in any available slot. If set to TRUE, then the corresponding property, RequirementsDescription, should specify the nature of the uniqueness or purpose of the card.

  • Status
  • The Status property is a string indicating the current status of the object. Various operational and non-operational statuses can be defined. Operational statuses are "OK", "Degraded" and "Pred Fail". "Pred Fail" indicates that an element may be functioning properly but predicting a failure in the near future. An example is a SMART-enabled hard drive. Non-operational statuses can also be specified. These are "Error", "Starting", "Stopping" and "Service". The latter, "Service", could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is on-line, yet the managed element is neither "OK" nor in one of the other states.

  • Tag
  • The Tag property uniquely identifies the base board of the system.
    Example: Base Board

  • Version
  • A string indicating the version of the physical element.

  • Weight
  • The weight of the physical package in pounds.

  • Width
  • The width of the physical package in inches.


  • IsCompatible
  • The IsCompatible method verifies whether the referenced physical element may be contained by or inserted into the physical package. The return value should be 0 if the request was successfully executed, 1 if the request is not supported and some other value if an error occurred. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier.
