Coreboot: Preparation and Build

Research the specific hardware components of your x230 to confirm Coreboot compatibility and identify the correct flashing procedure.

Identify the tools required for external flashing (e.g., Raspberry Pi, SOIC8 clip, jumper wires) and explain the function of each.

Explain the purpose of the 'me_cleaner' script and how it neutralizes the Intel ME by removing most of its code modules.

Set up the Coreboot build environment by installing the required toolchain and cloning the source code.

Create and verify multiple redundant backups of the original proprietary BIOS firmware.

Produce a neutralized Intel ME firmware region using the 'me_cleaner' script on a backed-up BIOS image.

Configure the Coreboot build for the x230, selecting a payload (e.g., SeaBIOS) and specifying the neutralized ME region.

Compile the configured source code to produce a final Coreboot ROM image.
