While doing Coreboot + Tiano Core (or UEFI) in flash & GRUB2 + Ubuntu on drive, you should check and see if you see the same as me?! At least using stock BIOS??? _______
Hi Zoran, I think you missed some lines in my previous replies:
I’ve tried the stock UEFI Bios (on flash) + Grub2(EFI)/Ubuntu (on 1st disk, 1st to boot) + Clover(EFI)/macOS (on 2nd disk), well, it worked, Grub(EFI) can chainload to boot Clover (which boot macOS). So yes, I agree with you with the efi hierarchy, and grubx64.efi. It works with stock EFI Bios.
Then I’ve tried Coreboot/TianoCore (on flash) + Grub2(EFI)/Ubuntu (on disk), and it didn’t worked. I have a black screen with a blinking cursor (top left screen).
So I’ve tried to build a Grub2 EFI as payload for Coreboot, but without success.
Nope. You have GRUB2 on drive, already. You should build Coreboot + Tiano Core in flash (then have drive GRUB2 + Ubuntu), but here somebody from Coreboot-GOOGLE folks should give you a hand.
Should work, as my best understanding is.
