Introduction
|
|
============
|
|
|
|
Libreboot has support for this, in the Git repository and release versions
|
|
from 20230423 onwards.
|
|
|
|
Brief board info
|
|
----------------
|
|
|
|
HP Elite 8200 SFF is a small-form-factor desktop of Intel Sandybridge platform
|
|
which you can read more about here:
|
|
|
|
<https://support.hp.com/gb-en/product/hp-compaq-8200-elite-small-form-factor-pc/5037931>
|
|
|
|
MT is an identical board with a larger chassis and more powerful power supply:
|
|
|
|
<https://support.hp.com/gb-en/product/hp-compaq-8200-elite-desktop-pc-series/5037940>
|
|
|
|
Here's the [Technical Reference Manual](https://web.archive.org/web/20160109143257/https://h10032.www1.hp.com/ctg/Manual/c02778024.pdf).
|
|
This system supports Ivy Bridge processors too. The original BIOS
|
|
won't even POST with those, but with Libreboot they work fully.
|
|
|
|
Installation of Libreboot
|
|
-------------------------
|
|
|
|
You can actually just compile the Libreboot ROM for this, and flash the
|
|
entire ROM.
|
|
|
|
Internal flashing from OEM BIOS is possible by setting a jumper
|
|
on the board. Step by step instructions for this are below.
|
|
|
|
The *coreboot* project proper has technical details on why this works if
|
|
you are interested. It also has external flashing instructions if you need
|
|
to recover from an unbootable BIOS:
|
|
|
|
<https://doc.coreboot.org/mainboard/hp/compaq_8200_sff.html>
|
|
|
|
You can build the images for it in Libreboot like so:
|
|
|
|
./build roms hp8200sff_8mb
|
|
|
|
More information about building ROM images can be found in
|
|
the [build guide](../build/).
|
|
|
|
If you plan on using a graphics card (other than the integrated graphics of
|
|
your CPU), choose one of the files which name contains both "seabios" and
|
|
"txtmode".
|
|
|
|
This is a *Sandybridge* board which means that a neutered ME image is required
|
|
if you wish to flash the ME region. Libreboot's build system automatically
|
|
downloads, neuters (using `me_cleaner`) and inserts this if compiling from
|
|
source.
|
|
|
|
If you're using *Libreboot release* ROM images, the ME image has been scrubbed
|
|
and you must re-insert it. Use the information on this guide to know how
|
|
to do that:
|
|
|
|
[Insert vendor files on Intel Sandybridge/Ivybridge/Haswell
|
|
platforms](../install/ivy_has_common.md)
|
|
|
|
You may also wish to change the *default MAC address* if you're planning to
|
|
use the onboard Intel Gigabit Ethernet. You can do this using the information
|
|
in the same guide linked above, or read the nvmutil manual:
|
|
|
|
[Modify MAC addresses with nvmutil](../install/nvmutil.md).
|
|
|
|
Internal flashing from vendor BIOS
|
|
----------------------------------
|
|
|
|
The vendor BIOS imposes write-protections in the Flash Descriptor and
|
|
runtime. However, the flash descriptor can be bypassed by bridging a
|
|
jumper and the runtime protections only apply to a fixed address block.
|
|
Since neutering the Management Engine frees up a lot of space, we can
|
|
just install an intermediate Libreboot image there. This removes all
|
|
write-protections so has the same end result as external flashing:
|
|
a completely unlocked system.
|
|
|
|
Power off the computer. Remove the side panel.
|
|
Near the back USB ports find the jumper labelled **FDO**.
|
|
|
|
|
|
|
|
You need to short the two pins circled. Use a
|
|
[jumper block](https://en.wikipedia.org/wiki/Jumper_(computing)) if you
|
|
have one but a screwdriver will do the job fine too. Hold the tip
|
|
between the pins until you can see the normal BIOS boot screen.
|
|
|
|
|
|
|
|
Boot into an OS supported by flashprog. On Linux, make sure you add the
|
|
kernel parameter **iomem=relaxed** which disables memory protections that
|
|
prevent BIOS flashing.
|
|
|
|
NOTE: Libreboot standardises on [flashprog](https://flashprog.org/wiki/Flashprog)
|
|
now, as of 27 January 2024, which is a fork of flashrom.
|
|
|
|
Now, run this command:
|
|
|
|
flashprog -p internal -c MX25L6406E/MX25L6408E
|
|
|
|
The output should contain the text "The Flash Descriptor Override
|
|
Pin-Strap is set". If it doesn't, start again from the beginning.
|
|
|
|
Now build the **4** MiB Libreboot image.
|
|
|
|
./build roms hp8200sff_4mb
|
|
|
|
More information about building ROM images can be found in
|
|
the [build guide](../build/).
|
|
|
|
Also build `ifdtool`. It will be needed soon.
|
|
|
|
cd src/coreboot/default/util/ifdtool
|
|
make
|
|
sudo make install
|
|
|
|
Now choose the image you want from `bin/hp8200sff_4mb`.
|
|
We'll refer to it as `libreboot4.rom`. We need to pad it to 8 MiB:
|
|
|
|
dd if=/dev/zero bs=4M count=1 >> libreboot4.rom
|
|
|
|
Flash the Libreboot image with a tweaked layout:
|
|
|
|
ifdtool libreboot4.rom -f layout
|
|
flashprog -p internal -c MX25L6406E/MX25L6408E -w libreboot4.rom -l layout -i fd -i gbe -i bios -i me
|
|
|
|
Power off the computer. Make sure to power off, rebooting is not enough!
|
|
|
|
Power on the computer.
|
|
Now we can flash the full 8 MiB image. Boot to an OS with flashprog
|
|
again. On linux, remember the **iomem=relaxed** kernel parameter.
|
|
|
|
NOTE: Libreboot standardises on [flashprog](https://flashprog.org/wiki/Flashprog)
|
|
now, as of 27 January 2024, which is a fork of flashrom.
|
|
|
|
Pick a Libreboot image of your choice from `bin/hp8200sff_8mb`
|
|
or from a release archive. We'll refer to it as `libreboot8.rom`.
|
|
|
|
flashprog -p internal -c MX25L6406E/MX25L6408E -w libreboot8.rom
|
|
|
|
Power cycle the computer again.
|
|
|
|
HP 6200 Pro Business PC
|
|
-----------------------
|
|
|
|
According to this page from the vendor, HP BIOS updates are the same on both
|
|
the 8200 SFF Elite *and* 6200 Pro Business desktop PCs; therefore, we believe
|
|
that the Libreboot config for 8200 SFF will *also* work on 6200 Pro Business
|
|
PCs. That page is here:
|
|
<https://support.hp.com/fi-fi/drivers/selfservice/swdetails/hp-compaq-8200-elite-small-form-factor-pc/5037931/swItemId/vc-229778-2>
|
|
|
|
The config for this board is courtesy of *Riku Viitanen* (`Riku_V` on Libreboot
|
|
IRC), who tested and confirmed the following functionality:
|
|
|
|
* Sandy Bridge (i5-2400) and Ivy Bridge (i5-3570S) CPUs
|
|
* 4x8 GB RAM (Sandy Bridge: 1333MHz, Ivy Bridge: 1600MHz)
|
|
* PS/2 keyboard and mouse
|
|
* USB keyboard (a bit laggy on GRUB)
|
|
* Boot from USB and DVD
|
|
* Gigabit ethernet
|
|
* VGA and DisplayPort (Intel graphics), with libgfxinit (native video init)
|
|
* Headphone output, PC speaker
|
|
* S3 suspend, wake on USB keyboard
|
|
* lm\_sensors outputs CPU core temperatures only
|
|
* Both PCIe x16 slots, external GPU works with SeaBIOS
|
|
* PCI
|
|
* SATA
|
|
* USB ports
|
|
* Serial port (RS-232)
|
|
* Wake on LAN
|
|
|
|
At the time of adding this board to Libreboot, the following is untested:
|
|
|
|
* Parallel port (internal header on the board)
|
|
* Floppy drive. The case has a spot for it, but I can't find the header (P10).
|
|
|
|
According to the initial coreboot port from 2018, the following also works:
|
|
|
|
* EHCI debug (not enabled by Libreboot configs)
|
|
* Native (libre) raminit with up to four DIMM modules (also tested by Riku and
|
|
confirmed working, with 32GB RAM installed as 4x8GB)
|
|
|
|
TPM
|
|
---
|
|
|
|
According to git logs, TPM should work, and a commit from 2018 at revision
|
|
ID `39d0e2a2cf45e28cdddd0fe0c88f94ce527ab1ef` in coreboot makes the TPM visible
|
|
to operating systems.
|
|
|
|
PSU Fan control
|
|
---------------
|
|
|
|
See coreboot commit `9bd601584350f51f112b15a7369f9aa82f1d0919` - labelled
|
|
by commit message `superio/nuvoton/npcd378: Add PSU fan control`.
|
|
|
|
Per this commit, SuperIO-based fan control is supported on HP Elite 8200 SFF.
|
|
|
|
TODO for testing the above is here:\
|
|
<https://codeberg.org/libreboot/lbmk/issues/9>
|
|
|
|
This is controlled via `nvramtool` to modify the value in sram. See:
|
|
|
|
* `psu_fan_lvl=3` <-- default setting in coreboot, and Libreboot.
|
|
|
|
Other values possible: from reading the source code, it is implied that the
|
|
number can be between 0 and 7. If the value is set higher than 7, it will
|
|
default back to 3.
|
|
|
|
Libreboot locks CMOS/NVRAM settings, but you can change the default setting in
|
|
the *ROM* by using the `-C` option in nvramtool. You can find this under the
|
|
directory `src/coreboot/default/util/nvramtool` when downloading coreboot inside
|
|
of lbmk by running the command:
|
|
|
|
./update trees -f coreboot default
|
|
|
|
Go in there and type `make` to build nvramtool. Simply run nvramtool without
|
|
arguments, and it will show a list of options.
