This laptop has upgradeable GPU: it has a socketed MXM-A 3.0 card. So far, only Quadro 1000M and 2000M (which shipped with the laptop originally) have been tested with Libreboot.
These laptops shipped with eDP and LVDS panels. If you choose to upgrade the graphics card, make sure it is compatible with the panel you have. Use the following command to check:
xrandr
Or if using Wayland:
wlr-randr
If you have "LVDS-1 connected", your GPU upgrade needs to support LVDS. According to this forum thread, AMD's 1st gen GCN cards are the newest and most powerful to support LVDS. If you have an eDP panel, you should be able to use newer cards than that.
As long as the card has an onboard VBIOS, Libreboot will execute it and everything should work. However, this is currently untested.
Build ROM image from source
The build target, when building from source, is thus:
./mk -b coreboot hp8560w_8mb
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.
Remove the bottom cover. The SOIC-8 flash chip is next to the memory slot 2. You need to cut away a small piece of the clear plastic protection material to get to the chip.
For information about programming the chip, please refer to 25xx NOR flash instructions.
