if Tianocore doesn't show anything, it's the Linux graphics driver that initializes the display first. So you probably built coreboot without any UEFI-compatible means of graphics initialization. Bootloaders like GRUB don't know how to initialize graphics, so trying different Linux distributions seems futile. Here is what I would try: Find a second PC that boots in UEFI mode. Boot your Live-Linux on it, and add the `iomem=relaxed` in the GRUB menu. Note any keys you have to press or do it in parallel on both machines; so enter everything on your black-screen blindly and hope. Stupid procedure, but worth one shot at least before you waste more time trying to adapt boot media. Hope that helps, Nico _______________________________________________ coreboot mailing list -- [email protected] To unsubscribe send an email to [email protected]
