06h Version Byte String Number of the Null-terminated string. This comes from the FRU field
“Product Version”.
07h Serial Number Byte String Number of the Null-terminated string. This comes from the FRU field
“Product Serial Number”.
08h UUID 16 bytes Varies This is from the value stored in non-volatile RAM (either BIOS Flash or
BMC).
18h Wakeup Type
Interrupt Info
Byte Enum See the System Management BIOS Reference Specification, Version 2.5
Section 3.3.2.1 for meaning.
19h SKU Number Byte String Number of the Null-terminated string. This text string is used to identify a
particular computer configuration for sale. It is sometimes also called a
product ID or purchase order number. This number is frequently found in
existing fields, but there is no standard format. Typically for a given system
board from a given OEM, there are several unique processor, memory, hard
drive, and optical drive configurations.
1Ah Family Byte String Number of the Null-terminated string. This text string is used to identify the
family a particular computer belongs to. A family refers to a set of computers
that are similar but not identical from a hardware or software point of view.
Typically, a family is composed of different computer models, which have
different configurations and pricing points. Computers in the same family
often have similar branding and cosmetic features.
20.5.2.3 Type 2 Structure — Base Board Information
The SMBIOS Type 2 structure is populated by obtaining information from the product area of the BMC FRU. The
information obtained from this area can be customized. See the
Platform Management FRU Information Storage
Definition,
Version 1.0 for more information.
20.5.2.4 Type 3 Structure — System Enclosure or Chassis
The SMBIOS Type 3 structure is populated by obtaining information from a special chassis name area of the FRU file.
This information is customized by the OEM. The BIOS takes the information populated in this file to fill the SMBIOS
structure and setup.
20.5.2.5 Type 4 Structure — Processor Information
The SMBIOS Type 4 structure describes the attributes of a single physical processor. The SMBIOS Table Structure
contains one Type 4 structure for each physical processor socket in the server.
Table 151. SMBIOS Type 4 Structure
Offset Name Length Value Description
00h Type Byte 4 Processor information indicator.
01h Length Byte 28h Number of bytes in this type structure.
02h Handle Word Varies The number of this structure in the table.
04h Socket
Designation
Byte String Number of the Null-terminated string. Contains the reference designator on
the silkscreen of the processor socket.

®
Xeon
® ®
Processor family..
07h Processor
Manufacturer
Byte String
Number of the Null-terminated string. String contains “Intel
®
Corporation”.
08h Processor ID QWord Varies Contains the results of the CPUID instruction with EAX = 1 as follows:
Offset 08h-0Bh: EAX Offset 0Ch-0Fh: EDX
10h Processor
Version
Byte String Number of the Null-terminated string that describes the processor. This
string is returned from the processor.
11h Voltage Byte Varies Bit 7 - 1

Current processor voltage * 10 - 1.8V =
92h
12h External Clock Byte Varies External clock speed in MHz.
14h Max Speed Word Varies Maximum internal processor speed in MHz.
16h Current Speed Word Varies Current internal processor speed in MHz.
18h Status Word Varies Bit 7
0 = Reserved
Bit 6
0 = Socket unpopulated
1 = Socket populated
Bits 5:3
