Board port: HP Elite 8200 SFF desktop PC

[githubisnonfree]

Libreboot recently added support for this machine. Some nice things:

• Sandybridge
• has TPM
• 8MB flash
• ME size 80KB when neutered

So, heads can fit nicely in flash on this machine, same tight squeeze as on an X220.

Perfect heads machine imo.

The libreboot port is here:

announcement: https://libreboot.org/news/hp8200sff.html

and check in lbmk:

blobs/hp8200sff/ifd.bin and gbe.bin

resources/blobs/sources - has links in it to HP updates for ME extraction

and of course libreboot has blobutil:

script in root of lbmk: blobutil

and download/extract/insert scripts: resources/scripts/blobs/

your current download/extract logic for heads is hardcoded to handle X220 X230 etc

you will need to adapt the logic to handle LZMA archives, and bruteforce traversal/searching to find extracted ME. have a look at the logic here in this script of lbmk, to know how i implemented that for HP updates (see: function named Bruteforce_extract_me):

script path in lbmk: resources/scripts/blobs/download

i've half a mind to port this myself, but you can get these machines fully assembled on ebay for like $80 US or less. I got mine for £35 GBP
