Hardware Management Overview
3.3 Field 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.
