Structure Description:

    This structure defines the entry point structure for the SMBIOS tables.
    On legacy PC/AT systems, this structure is located somewhere between
    address 0xF0000 and 0xFFFFF aligned to a 16-byte boundary.

Members:

    AnchorString - Stores the string constant '_SM_'.

    Checksum - Stores the checksum of the table bytes. When all bytes including
        this checksum are summed, the result should be zero. The length to
        checksum is the entry point length field.

    EntryPointLength - Stores the length of the entry point structure, and the
        number of bytes to checksum. This should be 0x1F.

    MajorVersion - Stores the major version of the specification implemented in
        this table structure.

    MinorVersion - Stores the minor version of the specification implemtned in
        this table structure.

    MaxStructureSize - Stores the size of the largest structure, in bytes, and
        encompasses the structure's formatted area and text strings.

    EntryPointRevision - Stores the format of the formatted area. This is
        currently set to zero, and the formatted area is reserved.

    FormattedArea - Stores reserved bytes that may be used in the future.

    IntermediateAnchor - Stores the intermediate anchor string "_DMI_" (not
        null terminated).

    IntermediateChecksum - Stores the checksum such that all bytes starting at
        the intermediate anchor and going for length 0xF sum to zero.

    StructureTableLength - Stores the length of the SMBIOS structure table,
        in bytes.

    StructureTableAddress - Stores the 32-bit physical address of the read-only
        SMBIOS structure table. These structures are fully-packed.

    NumberOfStructures - Stores the count of structures in the array.

    BcdRevision - Stores the major and minor SMBIOS specification version
        numbers in binary coded decimal form. Revision 2.1 for instance would
        have a value 0x21.

Structure Description:

    This structure defines the common header that all SMBIOS structures start
    with.

Members:

    Type - Stores the structure type, which defines the remaining content of
        the structure after this header.

    Length - Stores the length of the formatted area of the structure. The
        unformatted area always ends with a double null character (two zero
        bytes).

    Handle - Stores the structure's handle, a unique 16-bit number in the range
        of 0x0000 to 0xFFFE (or 0xFEFF for version 2.1 and later).
