I bought an A770 graphics card a month ago to use it in a machine with coreboot, this machine has ME disabled, and it is also pcie 3.0(pcie version not matter much), the problem is that i can’t get the A770 card to work, trying to find out why not working, i saw a video of an intel engineer saying that it requires ME enabled to work properly, since then i stopped get work my A770. I wanted the Intel card A770 card because it is AV1 encoder and free software driver, plus powerful gpu.
My computer baseboard it is: https://www.phoronix.com/news/ASRock-B75-Coreboot
I ordered one few days ago, idea is to use it as a low performance workstation. Worst case, it’ll end up as a NAS or home server of some kind. It should arrive in about a month, I hope, so I’ll report my impressions then.
