Introduction
============
This is a portable, 11.6" Ivy Bridge platform from HP.
**Unavailable in Libreboot 20230625 or earlier. You must [compile from
source](../build/), or use the next release after Libreboot 20230625.**
Build ROM image from source
---------------------------
The build target, when building from source, is thus:
./build boot roms hp2170p_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; although
the flash is socketed, hot-swapping is generally a bad practise and must be
avoided.**
Otherwise, external flashing is simple, but *quite different* from most
laptops! The flash is a SOIC8 IC like you'd expect, but it's *in a socket*.
Remove those two screws and cover on the underside, and then the flash is in
this socket which you can open:

<img tabindex=1 class="l" src="https://av.libreboot.org/hp2170p/hp2170p_socket.jpg" /><span class="f"><img src="https://av.libreboot.org/hp2170p/hp2170p_socket.jpg" /></span>
For general information, please refer to [25xx NOR flash
instructions](../install/spi.md) - that page refers to use of socketed flash.
For this board, you can use a Raspberry Pi or similar flasher if you wish, wired
to a spring socket adapter (SOP to DIP adapter) in a breadboard. In my case, I
opted for use of a 3.3v-modded CH341A device.
<img tabindex=1 class="l" style="clear:left;" src="https://av.libreboot.org/hp2170p/ch341a_socket_soic8.jpg" /><span class="f"><img src="https://av.libreboot.org/hp2170p/ch341a_socket_soic8.jpg" /></span>
Here, the flash is inserted into the SOP to DIP adapter, which is then put into
the ZIF socket on the CH341a device. This is the black version which has 5V
logic levels, but it can (read: MUST) be modified for correct 3.3v logic levels.
The [main 25xx flashing guide](../install/spi.md) documents this; some other
models may already be 3.3v, or have switchable logic levels like on some newer
revisions of CH341A. Please ensure that you run it at the correct voltage.
