Open source BIOS/UEFI firmware
------------------------------

This document will teach you how to install Libreboot, on your
HP EliteBook 8470p laptop motherboard.
Libreboot is a [Free Software](https://writefreesoftware.org/learn) project
that replaces proprietary BIOS/UEFI firmware.

Official information about the laptop can be found here:
<https://support.hp.com/gb-en/document/c03374369>

This is a beastly 14" Ivy Bridge platform from HP.
**NOTE: Until otherwise stated, only the Intel GPU variant is supported in
Libreboot.**

### Build ROM image from source

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

	./mk -b coreboot 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](../install/ivy_has_common.md) 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](../install/nvmutil.md).

### Flash a ROM image (software)

If you're already running Libreboot, and you don't have flash protection
turned on, [internal flashing](../install/) 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](../install/spi.md).

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)
