global authority (This is similar to the <Schema Name>_<Class Name> structure of

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 re-used to identify different underlying (real-world) elements. If the 
above preferred algorithm is not used, the defining entity MUST assure that the 
resultant InstanceID is not re-used across any InstanceIDs produced by this or other 
providers for this instance's NameSpace. For DMTF defined instances, the 
preferred 
algorithm MUST be used with the<OrgID> set to CIM.
MaxLength
This property specifies the maximum string length allowed when modifying this BIOS 
attribute. A value of NULL defines the maximum length is unknown. A value of 0 defines 
the maximum length as 18446744073709551615, the limitation of the property definition 
as uint64.

Property Description
AttributeName 
A string identifying the structured element name for a BIOS attribute using the format (:) in 
which , does contain a colon (:). The value of is a copyrighted, trademarked or otherwise 
unique name that is owned by the entity defining the , or is a registered ID that is assigned 
to the entity by a recognized global authority. For DMTF defined identifiers, the is set to 
DMTF and the is specified in the BIOS Attribute Registry.
CurrentValue
An array of strings representing the current value or values of the BIOS Attribute.
InstanceID 
Within the scope of the instantiating Namespace, InstanceID opaquely and uniquely 
identifies an instance of this class. In order to ensure uniqueness within the NameSpace, 
the value of InstanceID SHOULD be constructed using the following preferred 
algorithm: :Where and are separated by a colon (:), and where MUST include a copyrighted, 
trademarked or otherwise unique name that is owned by the business entity creating/
defining the InstanceID, or is a registered ID that is assigned to the business entity by a 
recognized global authority (This is similar to the _ structure of Schema class names.) In 
addition, to ensure uniqueness MUST NOT contain a colon (:). When using this algorithm, 
the first colon to appear in InstanceID MUST appear between and . is chosen by the 
business entity and SHOULD not be re-used to identify different underlying (real-world) 
elements. If the above 
preferred algorithm is not used, the defining entity MUST assure 
that the resultant InstanceID is not re-used across any InstanceIDs produced by this or 
other providers for this instance's NameSpace. For DMTF defined instances, the preferred 
algorithm MUST be used with the set to CIM.
MaxLength
This property specifies the maximum string length allowed when modifying this BIOS 
attribute. A value of NULL defines the maximum length is unknown. A value of 0 defines the 
maximum length as 18446744073709551615, the limitation of the property definition as 
uint64.
StringType
The StringType property provides management applications with information defining 
implementation's capabilities regarding string values. A value of ASCII indicates a plain text 
formatting with no tabs formatting or bolds, plain text. A value of hex indicates a simple 
encoding of the numerals 0 to 9 and the letters A to F and is not case sensitive. A value of 
unicode indicates fully multi-lingual text support. A string BIOS Attribute with value of regex
