Hi, Thanks for the reply. To answer your questions: - I'm running linear frame buffer, but not at native resolution. If I do, the boot menu text gets too small since this is a 13" 2k screen. - Payload is Tianocore - Windows is installed in UEFI (these last two have been the same configuration as always)
I didn't know the commit hash was embedded in the binary, I'll take a look and see if I can reproduce a working build. I do know that my display needed a patch to work correctly before this update <https://review.coreboot.org/c/coreboot/+/35898>, but I'm unclear if THAT's what caused Windows to not work correctly (i.e whether the patch worked better or not). I guess if I start with the commit I originally used I can play around with cherry-picking that commit vs the previous patch).
