Download from release

If you’re using a release ROM, please ensure that you’ve inserted extra firmware required refer to the guide for that (, failure to adhere to this advice will result in a bricked machine):

• Intel ME (vendor blob)

Build from source

./mk -b coreboot hp_elitebook_9470m_16mb

Default Libreboot firmwares updatable.

Remove the battery.

Open the two screws marked with the three-disc icons. Slide the HDD panel out and remove it.

The flash chip is now comfortably accessible. Now refer to the external programming guide for guidance on how to program Libreboot on it.

Some part of the board might turn on when programming. If programming fails, you might have to attach the laptop to a charger. Make sure the laptop powers off & disconnected the vcc on the programmer before running flashprog. No LEDs should be lit.

Check the hw-flashing guide before moving onto the next step below.

Flash it: (With rpi-pico as an example, edit the line if needed.)

flashprog -p serprog:dev=/dev/ttyACM0,spispeed=16M -w filename.rom

This platform uses an Intel Flash Descriptor, and defines an Intel GbE NVM region. As such, release/build ROMs will contain the same MAC address. To change the MAC address, please read nvmutil documentation.
