• 7:7 – End of List. Set to one for the last record.
• 6:4 – Reserved, write as 0h
• 3:0 – Record format version (=2h for this definition)
• 7:5 – Processors Boot Parameters Record version (=0h for this definition)
• 4:0 – Intel Record ID. For the Processors Boot Parameters Record, a value 03h
• 7:5 – Processor descriptor format version (=0h for this definition)
• 4:4 – New parameters. Set to one for newly defined parameters.
• 3:0 – Processor identifier. The following values should be used:
should be used
- 0h BMC
- 1h NPU#1
- 2h NPU#2
- 3h AP
This bit is set when new parameters have been defined and need to be
translated into flash configuration. This is an optimization that allows faster
startup, that is, the translation is only done when needed.
