Members
signature Signature: An ASCII string representation of the table identifier. This field shall be set to
the value 4E424654h (i.e. "NBFT", see #NBFT_HEADER_SIG).
length Length: The length of the table, in bytes, including the header, starting from offset 0h.
This field is used to record the size of the entire table.
major_revision
Major Revision: The major revision of the structure corresponding to the Signature field.
Larger major revision numbers should not be assumed backward compatible to lower major
revision numbers with the same signature.
checksum Checksum: The entire table, including the Checksum field, shall sum to 0h to be considered
valid.
oem_id OEMID shall be populated by the NBFT driver writer by an OEM-supplied string that identifies
the OEM. All trailing bytes shall be NULL.
oem_table_id
OEM Table ID: This field shall be populated by the NBFT driver writer with an OEM-supplied
string that the OEM uses to identify the particular data table. This field is particularly
useful when defining a definition block to distinguish definition block functions. The OEM
assigns each dissimilar table a new OEM Table ID.
oem_revision
OEM Revision: An OEM-supplied revision number. Larger numbers are assumed to be newer
revisions.
creator_id Creator ID: Vendor ID of utility that created the table. For instance, this may be the ID
for the ASL Compiler.
creator_revision
Creator Revision: Revision of utility that created the table. For instance, this may be the
ID for the ASL Compiler.
heap_offset Heap Offset (HO): This field indicates the offset in bytes of the heap, if any, from byte
offset 0h of the NBFT Table Header.
heap_length Heap Length (HL): The length of the heap, if any.
driver_dev_path_sig
Driver Signature Heap Object Reference: This field indicates the offset in bytes of a heap
object containing the Driver Signature, if any, from byte offset 0h of the NBFT Table Header.
minor_revision
Minor Revision: The minor revision of the structure corresponding to the Signature field. If
the major revision numbers are the same, any minor revision number differences shall be
backwards compatible with the same signature.
reserved Reserved.
