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.
