The structure types listed with a table have specific data that is filled in every BIOS. The Structure types without a table
either follow the SMBIOS specification for filling in its fields or have fields that are dynamically filled according to the
heading of the structure type.
20.5.2.1 Type 0 Structure — BIOS Information
The Type 0 structure contains information about the BIOS revision ID, the BIOS build date and the technologies
supported by the BIOS. Only one structure exists to describe the BIOS. No structures are present to describe option
ROMs.
Table 149. SMBIOS Type 0 Structure
Offset Name Length Value Description
00h Type Byte 0 BIOS information (type 0) indicator.
01h Length Byte 18h Both extension bytes are supported.
02h Handle Word Varies The number of this structure in the table.
04h Vendor Byte String Number of the Null-terminated string: “Intel Corporation”.
05h BIOS Version Byte String Number of the Null-terminated string:
Contains full Intel BIOS ID string.
06h BIOS Starting
A
ddress
Segment
Word Varies Segment location of the BIOS starting address.
08h BIOS Release
Date
Byte String Number of the Null-terminated string. Date is in mm/dd/yyyy format.
09h BIOS ROM Size Byte Varies (n) Size (n) where 64K*(n+1) is the size of the BIOS flash part. 4 MB (3Fh) is
reported in this field.
0Ah BIOS
Characteristics
QWord Bit Field See the System Management BIOS Reference Specification, Version 2.5,
section 3.3.1.1 for enumeration of values.
12h BIOS
Characteristics
Extension Bytes
Word Bit Field See the System Management BIOS Reference Specification, Version 2.5,
Section 3.3.1.2 for enumeration of values. Byte 1 and Byte 2 are supported.
14h System BIOS
Major Release
Byte Varies Identifies the major release of the System BIOS; for example, the value is
0Ah for revision 10.22 and 02h for revision 2.1.
This field and/or the System BIOS Minor Release field are updated each
time a System BIOS update for a given system is released. If the system
does not support the use of this field, the value is 0FFh for both this field
and the System BIOS Minor Release field.
15h System BIOS
Minor Release
Byte Varies Identifies the minor release of the System BIOS; for example, the value is
16h for revision 10.22 and 01h for revision 2.1.
016h Embedded
Controller
Firmware Major
Release
Byte Varies Identifies the major release of the embedded controller firmware; for
example, the value is 0Ah for revision 10.22 and 02h for revision 2.1. This
field and/or the Embedded Controller Firmware Minor Release field are
updated each time an embedded controller firmware update for a given
system is released. If the system does not have field upgradeable
embedded controller firmware, the value is 0FFh.
17h Embedded
Controller
Firmware Minor
Release
Byte Varies Identifies the minor release of the embedded controller firmware; for
example, the value is 16h for revision 10.22 and 01h for revision 2.1. If the
system does not have field upgradeable embedded controller firmware, the
value is 0FFh.
20.5.2.2 Type 1 Structure — System Information
The SMBIOS Type 1 record is populated by obtaining information from the product area of BMC FRU and from the
virtual product data area. The information obtained from the product area of the BMC FRU can be customized. See
Intel® Server System Integrated Baseboard Management Controller Core External Product Specification for the
specific server board for more information.
Table 150. SMBIOS Type 1 Structure
Offset Name Length Value Description
00h Type Byte 1 System information indicator.
01h Length Byte 1Bh Number of bytes in this type structure.
02h Handle Word Varies The number of this structure in the table.
04h Manufacturer Byte String Number of the Null-terminated string. This comes from the FRU field
“Product Manufacturer”.
05h Product Name Byte String Number of the Null-terminated string. This comes from the concatenation of
the FRU fields “Product Name” and “Product Part Number” with a space
character between the two strings.
