System76 Open Firmware
An open source distribution of firmware utilizing coreboot, EDK2, and System76 firmware applications.
Supported models
These models are supported and will receive updates through the firmware manager:
- bonw14
- darp6
- galp4
- lemp9
- oryp6
Other models may be in development or available without support, and can be
seen in the models/ directory.
If the device becomes bricked it will require restoring the current firmware using an external programmer. See flashing for details.
Schematics
Board schematics can be provided on request by sending an email to
firmware@system76.com with the subject line "Schematics for model", where
model is the name of a directory in the models/ directory, such as darp6.
You may not share these without explicit permission from System76.
Dependencies
Install toolchain
./scripts/deps.sh
Load Rust environment (or optionally reboot)
source ~/.cargo/env
Build firmware, replace qemu with your model (look in the models directory for examples)
./scripts/build.sh qemu
Emulate firmware, only available after building the qemu model
./scripts/qemu.sh
Intel Management Engine
The IME is present, but disabled. This is accomplished by sending a HECI command on boot, before RAM is initalized. This puts the IME in a state similar to setting the HAP bit on earlier platforms. me_cleaner is not used as it does not support IME version 14.0.
