T480 Blobs
Coreboot on the T480 requires the following binary blobs:
me.bin
- Consists of Intel’s Management Engine (ME), which was modified and deguarded using me_cleaner and deguard (written by Mate Kukri) to remove all but the modules which are necessary for the CPU to function.tb.bin
- Consists of Thunderbolt firmware.gbe.bin
- Consists of hardware/software configuration data for the Gigabit Ethernet (GbE) controller.ifd_16.bin
- Consists of the Intel Flash Descriptor (IFD).
Heads supplies an IFD and GbE blob, which were copied from libreboot. We changed the MAC address of the GbE blob to 00:de:ad:c0:ff:ee
using nvmutil, to support anonymity and build reproducibility.
When building any T480 board variant with make
, the build system will download a copy the Intel ME. me.bin
was extracted from a Dell-Inspiron Windows installer firmware update.
