HP Elite 8200 SFF and 6200 Pro Business true

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

Here's the Technical Reference Manual

Installation of Libreboot

TODO: this patch is now in coreboot gerrit:
https://review.coreboot.org/c/coreboot/+/74248
(more notes about internal flashing)
also:
https://www.reddit.com/r/coreboot/comments/12nux51/hp_elite_8200_sff_coreboot_port_current_state/ - see notes about 8300

You can actually just compile the Libreboot ROM for this, and flash the entire ROM, then flash it. The coreboot project proper, has information about this:

https://doc.coreboot.org/mainboard/hp/compaq_8200_sff.html

Refer to the coreboot guide for flashing instructions, and you can build the images for it in Libreboot like so:

./build boot roms hp8200sff_8mb

More information about building ROM images can be found in the build guide.

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 binary blobs on Intel Sandybridge/Ivybridge/Haswell platforms

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.

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 and USB keyboards
  • 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

At the time of adding this board to Libreboot, the following is untested:

  • Serial port and parallel port (internal header on the board) and PS/2 mouse- NOTE: Serial port believed to work, according to initial coreboot commit from revision 6308e0e92f624cb18a875ed04e41e1d15fc91054 in 2018
  • Wake on LAN
  • Internal flashing from OEM BIOS - TODO: Riku spoke to someone on IRC who said it might be possible, so this should be investigated. - NOTE: coreboot git logs also suggest that this is possible.
  • Does the OEM BIOS support Ivy Bridge chips? People on various forums say no, but of them say the chipset is the reason. No one seems to have actually tested, or at least haven't told about it.
  • 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)
  • USB ports
  • 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 coreboot/default/util/nvramtool when downloading coreboot inside of lbmk by running the command:

./download coreboot default

Go in there and type make to build nvramtool. Simply run nvramtool without arguments, and it will show a list of options.
