- Set up external flashing hardware (Raspberry Pi Pico + SOIC8 clip)
- Build Libreboot from source
- Flash Libreboot to your laptop's BIOS chip
- Configure bootloader options
Time required: 3-5 hours
Difficulty: Advanced
Estimated cost: $15-30 (Raspberry Pi Pico + SOIC8 clip + jumper wires)
Prerequisites: Supported laptop (ThinkPad recommended), Raspberry Pi Pico, SOIC8 clip
This guide assumes you're building a Bitcoin Computer or Air-Gapped Computer. If you're not sure why open-source firmware matters, see those guides first.
Why Libreboot?
For a Bitcoin-focused laptop, security and privacy are paramount. Libreboot provides:
| Benefit | Description |
|---|---|
| No backdoors | Removes Intel ME/AMD PSP surveillance components |
| Auditable code | Fully open-source, no hidden proprietary code |
| Reduced attack surface | Minimal firmware footprint |
| Faster boot | Less bloat means quicker startup |
For Bitcoiners who value sovereignty, Libreboot ensures your laptop runs only transparent, user-controlled software.
What is Libreboot?
Libreboot is a free, open-source alternative to proprietary BIOS and UEFI firmware. It’s based on Coreboot and removes closed-source code like Intel Management Engine (ME) and AMD Platform Security Processor (PSP), which are potential security risks. Libreboot works on specific Intel, AMD, and ARM-based motherboards, commonly found in older laptops and desktops.
It initializes your hardware (CPU, RAM, storage, etc.) and loads your operating system. Linux and BSD are well-supported, and help is available on the #libreboot channel on Libera IRC.
How Libreboot Works
Libreboot includes multiple bootloader options:
- GRUB – A flexible GNU bootloader for Linux and BSD.
- SeaBIOS – A lightweight BIOS-compatible option for legacy software.
- U-Boot – A simple UEFI bootloader for ARM and some x86/x86_64 systems.
All these options come bundled, letting you choose the right one when you boot.

Once you have Libreboot installed, use your laptop as a:
- Bitcoin Computer – For secure transaction creation and broadcasting
- Air-Gapped Computer – For offline seed generation and signing
