Processors Boot Parameters Record
This record, proprietary to Intel, contains a definition of the boot parameters for a
board processor (BMP or NPU). This record is used by the BMC to properly define board
processors’ (BMC or NPU) boot parameters. The processor boot parameters upgrade
procedure is described in

Memory type/Interface number:
7:5 – Memory type identifier. The following values should be used:
4:0 – Interface number
Memory Amount. An amount (in kB) of memory connected to the given NPU memory
interface (0h is reserved and means a co-processor (for example, TCAM) is connected to
the given NPU interface).
• 7:7 – End of List. Set to 1 for the last record.
• 6:4 – Reserved, write as 0h
• 3:0 – Record format version (=2h for this definition)
• 7:5 – Memory Amount Record version (=0h for this definition)
• 4:0 – Intel Record ID. For the Memory Amount Record, a value 02h should be used.
• 0h – SRAM
• 1h – DRAM
• 2h – Flash
