Introduction
|
||
|
|
============
|
||
|
|
|
||
|
|
**Unavailable in Libreboot 20231106 or earlier. You must [compile from
|
||
|
|
source](../build/), or use a release newer than 20231106.**
|
||
|
|
|
||
|
|
This is a beastly 14" Sandy 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:
|
||
|
|
|
||
|
|
./build roms hp8460pintel_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](../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 chip is visible by removing the "bottom door" panel. But the
|
||
|
|
frame makes it hard to put a clip on it, so it's recommended to follow the
|
||
|
|
HP [service manual](https://h10032.www1.hp.com/ctg/Manual/c03015458.pdf)
|
||
|
|
to remove the **bottom cover**, as it's called.
