Msvm_BIOSElement class

Represents the low-level software that is loaded into RAM to configure and start the system. The BIOS is not a logical device, hence the virtual BIOS should not be thought of as a virtual computer system device. As it is not a device, it does not have a corresponding resource pool. The BIOS object is associated with the virtual computer system through the Msvm_SystemBIOS association.

The following syntax is simplified Managed Object Format (MOF) code, and it includes all of the inherited properties.

Caption

Data type: string

Access type: Read-only

Qualifiers: MaxLen (64)

A short textual description (one-line string) of the object. This property is inherited from CIM_ManagedElement and it is always set to "BIOS".

ChassisAssetTag

Data type: string

Access type: Read-only

Automatically populated by the BIOS when the virtual machine is created.

ChassisSerialNumber

Data type: string

Access type: Read-only

Automatically populated by the BIOS when the virtual machine is created.

CodeSet

Data type: string

Access type: Read-only

Qualifiers: MaxLen (64)

The code set used by the software element. This property is inherited from CIM_SoftwareElement and it is set to NULL.

CurrentLanguage

Data type: string

Access type: Read-only

Qualifiers: ModelCorrespondence ("CIM_BIOSElement.ListOfLanguages")

The currently selected language for the BIOS. This property is inherited from CIM_BIOSElement and it is always set to "en|US|iso8859-1".

Description

Data type: string

Access type: Read-only

A textual description of the object. This property is inherited from CIM_ManagedElement and it is always set to "Microsoft Virtual BIOS".

ElementName

Data type: string

Access type: Read-only

A user-friendly name for the element. This property is inherited from CIM_ManagedElement and it is always set to "BIOS".

EmbeddedControllerFirmwareMajorRelease

Data type: uint8

Access type: Read-only

Qualifiers: Experimental

The major release of the embedded controller firmware. This property is inherited from CIM_BIOSElement and it is always set to 255.

EmbeddedControllerFirmwareMinorRelease

Data type: uint8

Access type: Read-only

Qualifiers: Experimental

The minor release of the embedded controller firmware. This property is inherited from CIM_BIOSElement and it is always set to 255.

HealthState

Data type: uint16

Access type: Read-only

The current health of the element. This property is inherited from CIM_ManagedSystemElement and it is always set to 5 (OK).

OK (5)

The element is fully functional and operates within normal operational parameters and without error.

Remarks

Access to the Msvm_BIOSElement class might be restricted by UAC Filtering. For more information, see User Account Control and WMI.
