I have checked some boards may be ported to libreboot(are supported in Coreboot without needing blobs)
*X301, Similar board as X200, Macronix chip and GM45
*Roda RK9 (SBC)
*RK886EX (Rocky III+) (Unknown status in latest coreboot, similar board to macbook 2,1)
*Lenovo Z61t (same board as X60)
*ASUS P5GC-MX (server)
*GIGABYTE GA-945GCM-S2L (945GC)
*Lenovo ThinkCentre A58
*Foxconn D41S (Pineview)
Thanks in advance
@allanherrera what about Asus P5QL-PRO? How do I check, if it's a good candidate?
For checking this you need first see if can be Corebooted https://coreboot.org/status/board-status.html, if it is check if you need blobs, if does cannot proceed, if doesn’t rejoice! You can ask for it!, if no Coreboot support to your board, you can check if your chipset is compatible here https://www.coreboot.org/Supported_Chipsets_and_Devices if it is you can port it to coreboot(lots of heavy work, there are giant guides for this), if isn’t you’re Pretty much screwed.
