Factory Description
Default
00h Chassis Info Area Starting Offset (CIAOFF): This field indicates the
starting offset in multiples of 8 bytes for the Chassis Info Area. A
value of 00h may be used to indicate the Chassis Info Area is not
present
00h Board Info Area Starting Offset (BIAOFF): This field indicates the
starting offset in multiples of 8 bytes for the Board Info Area. A value
of 00h may be used to indicate the Board Info Area is not present
01h Product Info Area Starting Offset (PIAOFF):
This field indicates the starting offset in multiples of 8 bytes for the
Product Info Area
0Fh MultiRecord Info Area Starting Offset (MRIOFF):
This field indicates the starting offset in multiples of 8 bytes for the
MultiRecord Info Area
00h Reserved
Impl Spec Common Header Checksum (CHCHK): Checksum computed over
bytes 0 through 6. The checksum is computed by adding the 8-bit
value of the bytes modulo 256 and then taking the 2's complement of
this sum. When the checksum and the sum of the bytes module 256
are added, the result should be 0h
Factory Description
Default
0Bh NVMe Record Type ID
2h Bit 7 - end of list; record format version = 2
28h Record Length (RLEN): This field indicates the length of the
MultiRecord Area in bytes.
Impl Spec Record Checksum: This field is used to give the record data a zero
checksum (i.e., the modulo 256 sum of the record data bytes from
byte offset 05 through the end of this record plus this checksum
byte equals zero).
Impl Spec Header Checksum: This field is used to give the record header a
zero checksum (i.e., the modulo 256 sum of the preceding record
bytes starting with the first byte of the header plus this checksum
byte equals zero.
00h NVMe MultiRecord Area Version Number: This field indicates the
version number of this multirecord. This field shall be set to 0h in
this version of the specification.
