Re: [coreboot] Intel G41 - Asrock G41M-GS: no coreboot screen output from Intel GPU on VGA
Its not a slow reacting monitor. I already pressed it blind before reporting the issue here without any success. Its a modern, fast reacting LED monitor (ccfl takes longer to turn on). I get immediately after powering on a coreboot screen on the monitor when i insert a PCIe graphics card into the PCIe slot but i need the working internal Intel GPU.

Just press ESC key during booting for Seabios and if everything in the video interface is properly configured by default you should see the boot menu.

I wrote the way i had build coreboot. Tianocore is not the default payload. The default payload recently is (i checked now) SeaBIOS 1.11.2 . I have not touched anything at the payload. I just leave everything default and would like to be able to see the output of coreboot so that i can choose for example to boot from a usb-pendrive.
What should i do now to get the <everything at default coreboot> to show output on the screen?

Hello h42 If you are using Tianocore you must use VESA framebuffer If Seabios use text mode Jose ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On August 14, 2018 2:41 PM, h42@memeware.net wrote:
I dont get anything on the screen from coreboot. The later os is displaying fine. How i build the image: ran on a fresh git cloned (from today) 'make menuconfig', chose just the mainboard manufacturer and the model, press esc, confirmed saving, ran 'make'. I installed this image and dont get any coreboot output on the screen. When i wait long enough, i get the output from the Linux OS on the screen.
