6.4.2 Block Elements<br />
6.4.2.1 DBHdr<br />
See ' 6.1 Common Dynamic Block Header' on page 31.<br />
6.4.2.2 Type<br />
Specifies the type of structure. Types 0 through 127 (7Fh) are reserved for and defined by the smbios<br />
specification. Types 128 through 256 (80h to FFh) are available for system- and OEM-specific<br />
information.<br />

6.4.2.3 Length<br />
Specifies the length of the formatted area of the structure, starting at the Type field. The length of<br />
the structure’s string-set is not included.<br />
6.4.2.4 Handle<br />
Specifies the structure’s handle, a unique 16-bit number in the range 0 to 0FEFFh. To improve<br />
cross vendor compatibility, the following Ids are defined for the purposes of EeeP. The handle can<br />
be used with the Get SMBIOS Structure function to retrieve a specific structure; the handle<br />
numbers are not required to be contiguous.<br />

6.4.3 SMBIOS Block String Storage convention<br />
Text strings associated with a given SMBIOS structure are returned in the dmiStrucBuffer, appended<br />
directly after the formatted portion of the structure. This method of returning string information<br />
eliminates the need for application software to deal with pointers embedded in the SMBIOS structure.<br />
Each string is terminated with a null (0x00) BYTE and the set of strings is terminated with an additional<br />
