Re: Some problems with graphic display when using coreboot + seabios.

> SeaBIOS is a legacy BIOS implementation, so no it can't boot UEFI boot media. Likewise, Tianocore is a pure UEFI implementation, and doesn't boot legacy boot media / legacy installed OSes. There should be a way to use SeaBIOS as a CSM for Tianocore, but currently it's not working / not implemented (I tried briefly awhile back but didn't have any luck).

I tried to follow the steps to build tianocore for SeaBIOS https://www.coreboot.org/TianoCore%C2%A0But I get these errors. It says it can't found nmake.exe... Is this should be build on Windows? How to setup the environment?

I tried the tianocore payload by selecting it and using all default settings. But I can't see anything like the SeaBIOS for me to select the boot media. But it does boot the archlinux in UEFI mode. I'm wondering is this the problem with my display (I have tried both "Use libgfxinit" and "Run VGA Option ROMs" with tianocore) or the tianocore has nothing to display to select boot media?

Tianocore by default can't boot Linux/Windows installed by legacy method (installed when using seabios). my goal is to add UEFI support through tianocore as seabios payload (or through tianocore's CSM compatibility support module? ). So that it can boot both UEFI installed Windows or legacy installed Windows like the vendor bios can do. How to achieve this?

The Tianocore package which ran on top of SeaBIOS, DuetPkg, was remove long
ago, so that's not a viable approach (and it was buggy AF anyway). You'd
need to build SeaBIOS as a CSM, package it with Tianocore, and add the
appropriate hooks. Then debug from there

It appears building SeaBIOS as CSM for Tianocore is quite hard and I have searched around there is no guide. Could we build two roms and use something like coreboot's fallback mechanism feature to achieve the hybrid boot goal? Like default to boot in Tianocore image but with an option to reboot to SeaBIOS image...

I'm wondering is this the problem with my display (I have tried both "Use libgfxinit" and "Run VGA Option ROMs" with tianocore) or the tianocore has nothing to display to select boot media?

Tianocore by default can't boot Linux/Windows installed by legacy method (installed when using seabios). my goal is to add UEFI support through tianocore as seabios payload (or through tianocore's CSM compatibility support module? ). So that it can boot both UEFI installed Windows or legacy installed Windows like the vendor bios can do. How to achieve this?

Some problems with graphic display when using coreboot + seabios.

[Rafael Send]

FWIW I use Grub to load either SeaBIOS or Tianocore at boot, defaulting to
Tianocore for this exact problem. Hope that's of some help :)

Some problems with graphic display when using coreboot + seabios.

[Benjamin Doron]

OVMF in TianoCore seems to have code in place for using SeaBIOS as a CSM,
but some of it may depend on their specific platform.

Some problems with graphic display when using coreboot + seabios.

[Dalao]

> FWIW I use Grub to load either SeaBIOS or Tianocore at boot, defaulting to Tianocore for this exact problem. Hope that's of some help :)

Cool! This is what I want. I have followed this tutorial (https://github.com/librecore-org/librecore/wiki/Chainloading-SeaBIOS-from-a-...) and now I'm able to use Grub to chainload SeaBIOS. But in order to load Tianocore, it appears there is no tutorial online. I tried to use the above method to chainload the Tianocore's build output file UEFIPAYLOAD.fd, but it can't load. So how you achieved this?

Could we build two roms and use something like coreboot's fallback mechanism feature to achieve the hybrid boot goal? Like default to boot in Tianocore image but with an option to reboot to SeaBIOS image...

There should be a way to use SeaBIOS as a CSM for Tianocore, but currently it's not working / not implemented (I tried briefly awhile back but didn't have any luck).

But it does boot the archlinux in UEFI mode. I'm wondering is this the problem with my display (I have tried both "Use libgfxinit" and "Run VGA Option ROMs" with tianocore) or the tianocore has nothing to display to select boot media?

Tianocore by default can't boot Linux/Windows installed by legacy method (installed when using seabios). my goal is to add UEFI support through tianocore as seabios payload (or through tianocore's CSM compatibility support module? ). So that it can boot both UEFI installed Windows or legacy installed Windows like the vendor bios can do. How to achieve this?

Some problems with graphic display when using coreboot + seabios.

[Rafael Send]

Hi,
I did have some trouble getting this to work correctly. I believe you must
add it to cbfs with "add-payload" and not just as a regular file.
If that doesn't work let us know, I'll take a look at what exactly I did.

Good luck,
R

Thank you, with the help of people on irc, now I have been able to make it work. At first I used the UEFIPAYLOAD.fd in tianocore's build output folder, it does not work. Then I extracted it from coreboot.rom, and it works. I will document the process for maybe someone will find this useful in the future:

Firstly I follow this guide to build seabios (https://github.com/librecore-org/librecore/wiki/Chainloading-SeaBIOS-from-a-...). But I just use the bios.bin.elf I did not use that vgabios.bin that display is not good on T420.

Next I build coreboot and select tianocore as payload, and then extract it.
cbfstool ./build/coreboot.rom extract -m x86 -n fallback/payload -f ./GrubPayloads/tianocore

Then I build coreboot again and select GRUB as payload with high-resulotion framebuffer, and add SeaBIOS, Tianocore and grub.cfg
cbfstool ./build/coreboot.rom add -n elf/seabios.elf -f ./GrubPayloads/bios.bin.elf -t raw
cbfstool ./build/coreboot.rom add-payload -n img/tianocore -f ./GrubPayloads/tianocore
cbfstool ./build/coreboot.rom add -n etc/grub.cfg -f ./GrubPayloads/grub.cfg -t raw

This will work, but without VBG BIOS, the DP output does not work on T420. So I add the VGA BIOS blob.
cbfstool ./build/coreboot.rom add -f pci8086,0166.rom -n pci8086,0166.rom -t optionrom

But it does boot the archlinux in UEFI mode. I'm wondering is this the problem with my display (I have tried both "Use libgfxinit" and "Run VGA Option ROMs" with tianocore) or the tianocore has nothing to display to select boot media?

Tianocore by default can't boot Linux/Windows installed by legacy method (installed when using seabios). my goal is to add UEFI support through tianocore as seabios payload (or through tianocore's CSM compatibility support module? ). So that it can boot both UEFI installed Windows or legacy installed Windows like the vendor bios can do. How to achieve this?

Some problems with graphic display when using coreboot + seabios.

[Rafael Send]

Hi,
Good to know, I actually at one point did the same (extract working
Tianocore from coreboot binary), so maybe that's how it worked.

Did you figure out why it works when you extract it, but not if you just
add the built blob?

Some problems with graphic display when using coreboot + seabios.

[Dalao]

I did a compare of the UFEIPAYLOAD.fd with the one extracted. There are some header starting with .ELF in the extracted one. It's possibly the reason why the extracted one works. The header is possibly added by cbfstool when it build the image.

I have followed this tutorial (>>>> https://github.com/librecore-org/librecore/wiki/Chainloading-SeaBIOS-from-a-... ) and now I'm able to use Grub to chainload SeaBIOS. But in order to load Tianocore, it appears there is no tutorial online. I tried to use the above method to chainload the Tianocore's build output file UEFIPAYLOAD.fd, but it can't load. So how you achieved this?

Could we build two roms and use something like coreboot's fallback mechanism feature to achieve the hybrid boot goal? Like default to boot in Tianocore image but with an option to reboot to SeaBIOS image...

Likewise, Tianocore is a pure UEFI implementation, and doesn't boot legacy boot media / legacy installed OSes. There should be a way to use SeaBIOS as a CSM for Tianocore, but currently it's not working / not implemented (I tried briefly awhile back but didn't have any luck).

But it does boot the archlinux in UEFI mode. I'm wondering is this the problem with my display (I have tried both "Use libgfxinit" and "Run VGA Option ROMs" with tianocore) or the tianocore has nothing to display to select boot media?

This time, I can't see the archlinux start screen as shown above, there is no display at the beginning. But I can hit the enter blindly.

Tianocore by default can't boot Linux/Windows installed by legacy method (installed when using seabios). my goal is to add UEFI support through tianocore as seabios payload (or through tianocore's CSM compatibility support module? ). So that it can boot both UEFI installed Windows or legacy installed Windows like the vendor bios can do. How to achieve this?

UEFI is such an abomination that using SeaBIOS may be the sanest
option even in 2030.
