The build target, when building from source, is thus:

./build roms hp8470pintel_16mb

Installation

Insert binary files

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)

Set MAC address

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.

Flash a ROM image (software)

If you're already running Libreboot, and you don't have flash protection turned on, internal flashing is possible.

Flash a ROM image (hardware)

REMOVE all power sources like battery, charger and so on, before doing this. This is to prevent short circuiting and power surges while flashing.

For general information, please refer to 25xx NOR flash instructions.

At this present time, disassembly instructions are unavailable from the Libreboot project, but you can search for HP's own hardware maintenance manual or look at videos online showing disassembly.

The flash is near the RAM, top side. (sorry, I forgot to take photos when testing this, but they can be added here at a later date)
