I believe it is one of the Reserved bits at 85:84 or 82, but not
certain. You can check ILB 514482.
Are the boards identical?
Are the sizes of flash identical?
Any hardware straps connected?
or are you replacing the CPU in the same board? If unique boards, I
would dump back the flash and verify.

I can work round that in the BAYTRAIL_FSP CoreBoot build but cannot install Linux, and I'm guessing that having a wonky device id may be involved. Has anyone else seen this and know the work around? I can't see anything about it on the Intel IBL.
