Intel® Server System "Emerald Ridge” Integrated BaseboardManagement Controller EPSAppendix A: OEM SDR RecordsByteName4: M Sensor # / FRU faultLED #DescriptionUp to N pairs of sensor # / FRU fault LED values..M = Total number of bytes in this sub-record. Upper boundon this value is 49; however this is constrained by the totalnumber of bytes allowed for an OEM SDR record (64,including a 5 byte header).Revision 1.0Intel ® Confidential 173
Appendix B: FirmwareDevice Information Block FormatIntel® Server System "Emerald Ridge” Integrated BaseboardManagement Controller EPSAppendix B: : Firmware Device InformationBlockFormatThe BMC hex file contains Device Info Blocks (DIBs) that utilities may use to perform updaterelatedoperations. These device info blocks are formatted as shown in the following tables.Table 97: Operational Code Info Block Version 6FieldSize (bytes)DescriptionCookie 16 String “*OpCodeInfo*” stored in hex file that indicates whether or not thehex file is valid.Version of Info Block 1 Version of info block that the hex file is compatible with. Version is 6 for thisspecification.Structure Size 1 Size of this structure, including checksum.Reserved (1) 2Start of Op Code 4 Offset of start of operational code image in flash.End of Op Code 4 Offset of last byte of operational code.Op Code Run 4 Offset of first instruction to execute in operational code.Reserved (2) 2Major FW Version 2 Major operational code firmware version.Minor FW Version 2 Minor operational code firmware version.Build Date 12 Hex file build date – formatted as __DATE__Build Time 12 Hex file build time – formatted as __TIME__Reserved (3) 2Checksum 2 Info block checksum, starting from “Cookie” to “Reserved (3)”Table 98: Boot Code Info Block Version 6FieldSize (bytes)DescriptionCookie 16 String “*BootInfo*” stored in hex file that indicates whether or not thehex file is valid.Version of Info Block 1 Version of info block that the hex file is compatible with.
