PROPERTY	SMS_REPORT	CIMTYPE	DESCRIPTION
BiosCharacteristics		UInt16	The BiosCharacteristics property identifies the BIOS characteristics supported by the system as defined by the System Management BIOS Reference Specification
BIOSVersion		String	The BIOSVersion array property contains the complete System BIOS information. In many machines, there can be several version strings stored in the Registry representing the system BIOS info. The property contains the complete set.
BuildNumber		String	The internal identifier for this compilation of this software element.
Caption		String	The Caption property is a short textual description (one-line string) of the object.
CodeSet		String	The code set used by this software element.
CurrentLanguage		String	The CurrentLanguage property shows the name of the current BIOS language.
Description		String	The Description property provides a textual description of the object.
IdentificationCode		String	The value of this property is the manufacturer's identifier for this software element. Often this will be a stock keeping unit (SKU) or a part number.
InstallableLanguages		UInt16	The InstallableLanguages property indicates the number of languages available for installation on this system. Language may determine properties such as the need for Unicode and bi-directional text.
InstallDate		DateTime	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.
LanguageEdition		String	The value of this property identifies the language edition of this software element. The language codes defined in ISO 639 should be used. Where the software element represents multi-lingual or international version of a product, the string multilingual should be used.
ListOfLanguages		String	The ListOfLanguages property contains a list of namesof available BIOS-installable languages.
Manufacturer		String	Manufacturer of this software element
Name		String	The name used to identify this software element
OtherTargetOS		String	The OtherTargetOS property records the manufacturer and operating system type for a software element when the TargetOperatingSystem property has a value of 1 ("Other"). Therefore, when the TargetOperatingSystem property has a value of "Other", the OtherTargetOS property must have a non-null value. For all other values of TargetOperatingSystem, the OtherTargetOS property is to be NULL.
PrimaryBIOS		Boolean	If true, this is the primary BIOS of the computer system.
ReleaseDate		DateTime	The ReleaseDate property indicates the release date of the Win32 BIOS in the Coordinated Universal Time (UTC) format of YYYYMMDDHHMMSS.MMMMMM(+-)OOO.
SerialNumber		String	The assigned serial number of this software element.
SMBIOSBIOSVersion		String	The SMBIOSBIOSVersion property contains the BIOS version as reported by SMBIOS.
SMBIOSMajorVersion		UInt16	The SMBIOSMajorVersion property contains the major SMBIOS version number. This property will be NULL if SMBIOS not found.
SMBIOSMinorVersion		UInt16	The SMBIOSMinorVersion property contains the minor SMBIOS Version number. This property will be NULL if SMBIOS not found.
SMBIOSPresent		Boolean	The SMBIOSPresent property indicates whether the SMBIOS is available on this computer system. Values: TRUE or FALSE. If TRUE, SMBIOS is on this computer.
SoftwareElementID		String	This is an identifier for this software element and is designed to be used in conjunction with other keys to create a unique representation of this CIM_SoftwareElement
SoftwareElementState		UInt16	The SoftwareElementState is defined in this model to identify various states of a software elements life cycle. - A software element in the deployable state describes the details necessary to successful distribute it and the details (conditions and actions) required to create a software element in the installable state (i.e., the next state). - A software element in the installable state describes the details necessary to successfully install it and the details (conditions and actions required to create a software element in the executable state (i.e., the next state). - A software element in the executable state describes the details necessary to successfully start it and the details (conditions and actions required to create a software element in the running state (i.e., the next state). - A software element in the running state describes the details necessary to monitor and operate on a start element.
Status		String	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.
TargetOperatingSystem		UInt16	The TargetOperatingSystem property allows the provider to specify the operating system environment. The value of this property does not ensure binary executable. Two other pieces of information are needed. First, the version of the OS needs to be specified using the OS version check. The second piece of information is the architecture the OS runs on. The combination of these constructs allows the provider to clearly identify the level of OS required for a particular software element.
Version		String	The Version property contains the version of the BIOS. This string is created by the BIOS manufacturer.
