Hi all- I already posted a related question over at InsanelyMac, but it was suggested elsewhere that I should check here, in particular with @Jake Lo since he seems to knowledgeable about iGPUs and I've gotten great help here in the past too. Anyway, I put the latest Coreboot on my X210, and have a (more or less) working Mojave install using OC 0.7.3. I then tried to duplicate the process to install Big Sur, but none of the frambuffer settings (or any that I can find so far) resulted in working acceleration. Out of curiosity, I tried the same thing with Monterey Beta 6 to see if anything would change, but it does not. I also updated OC to 0.7.4. Since I overwrote the Big Sur install with the Monterey one, this question should apply to the latter. As far as I can tell, my DVMT should already be at 64MB or higher (Coreboot guys tell me it's set to the max by default), and I don't need any stolenmem / fbmem lines for Mojave anyway. I've attached my current EFI, in case there's something obviously wrong - I'd love to get some ideas that I haven't tried yet, since I've seen plenty of builds with my CPU/GPU that seem to work. All the ones I've found so far have IDs that do NOT work for me, however... Cheers, R EFI.zip
