Intel MPCBL0001 Field Replaceable Unit FRU Information, PMC Data, Variable Size byte Data Type

Hardware Management Overview

3.3Field Replaceable Unit (FRU) Information

The FRU Information provides inventory data about the boards where the FRU Information Device is located. The part number or version number can be read through software.

FRU information in the MPCBL0001 includes data describing the MPCBL0001 board as per PICMG 3.0 Specification requirements. Additional multirecords will be added for the BIOS to write CPU information, BIOS version number, and PMC information to FRU data correctly. This information is retrieved by shelf manager (ShMC), enabling reporting of board-specific information through an out-of-band mechanism.

Following are the definitions for the multirecord implemented by the firmware as part of FRU data.
