[coreboot] Re: VBIOS/VBT in Coreboot

since you're using Tianocore, you'll need to set a VESA/hi-res framebuffer; VGA text mode doesn't work IIRC. You can set that under the Display options, but a better option than using/running a VBIOS would be to use the FSP/GOP init, since it automatically sets a hi-res framebuffer (usually equal

Hi, One additional thing happening in your system (not sure if this is related to the slowdown): during the kernel boot there is a delay of about six seconds while kernel is waiting for CPU1: [0.487263] Booting Node 0, Processors #1 [6.543573] CPU1: Not responding. See in the
