Building BIOS Architecture

Diagnostics identify the cause, location, extent, and likely consequence of abnormal system behavior.

Diagnostic processes may include:

self-tests;

communication tests;

state comparison;

dependency tracing;

event correlation;

sensor cross-checking;

configuration comparison;

command-response testing;

controlled functional testing;

inspection data analysis;

trend analysis;

AI-assisted anomaly analysis.

A Diagnostic Record shall identify:

diagnostic request;

initiating condition;

affected entities;

tests performed;

observations;

hypotheses;

confidence;

confirmed findings;

excluded causes;

recommended action;

safety restrictions;

responsible authority.

Diagnostics shall distinguish between:

symptom;

suspected cause;

confirmed cause;

contributing condition;

secondary consequence.

Automated diagnostics shall not perform hazardous tests without verifying isolation, occupancy, dependencies, and authority.

AI-generated diagnoses shall remain identified as recommendations or inferences until supported by the required evidence.

The BIOS shall support dependency-aware diagnosis. If several components fail simultaneously because of one unavailable resource, the system should identify the shared dependency rather than report each component as an independent failure.

Diagnostic access shall be role-controlled. Manufacturer tools shall receive access only to authorized products and required contextual information.
