BIOS Documentation

This folder contains repository-level documentation for the recovered Lenovo
HR650X / Intel Purley AMI UEFI BIOS tree.

Start Here

• Firmware Overview - high-level platform, package, and
  subsystem orientation.
• Boot and Runtime Lifecycle - phase-by-phase
  behavioural flow from PEI through DXE, SMM, setup, OS handoff, and runtime.
• Subsystem Behaviour Map - navigation map from
  externally visible behaviours to recovered module evidence.

Layout Evidence

• Original Source Layout Recovery - recovered
  package/source-path grouping from debug/assert/PDB/source-path evidence.
• Original Layout Evidence - machine-readable
  evidence generated by tools/recover_original_layout.py.

These docs describe recovered firmware evidence, not pristine vendor source.
Where behaviour is uncertain, prefer the module .c, .h, .md, and README
files as the authoritative local evidence.
