Symptoms

System Post Screen shows:

Neutral CPU is detected and Platform Secure Boot (PSB) has not been enabled.
Enabling PSB will permanently fuse the CPU to only work on Dell platforms.
Do you want to enable PSB and fuse the CPU now?

Cause

AMD EPYC Generation 2 processors also offer the AMD Secure Processor for cryptographic functionality for secure key generation and key management. This provides full stack encryption without any overhead for the processor.

In addition, for hardware-accelerated memory encryption for data-in-use protection, the security components in Rome processors include the AES-128 encryption engine, which is embedded in the memory controller and automatically encrypts and decrypts data in main memory with an appropriate key.

Resolution

AMD EPYC processors not shipped in the Dell Platform cause this message.

If enabled, the CPU is only usable in Dell Platform systems, choosing not to enable it allows you to continue until the next reboot. The question is returned and you must manually choose not to enable it. Review this document: Comprehensive Security on PowerEdge AMD EPYC Generation 2 (Rome) Servers
