Bernd,
Unlike OS/kernels, firmware requires a lot of learning (tens to hundreds of hours) before you will get the desired results if you are not using precompiled images. Make sure that you are prepared to make that investment before continuing or you will most likely get frustrated. Be prepared to understand how drivers on coreboot and OpenBIOS work, and how PC architecture works on this low level.
I think it would be useful for you to try and understand how the kconfig system in coreboot works. It lets you configure any ELF payload.
That said, your approach should be
- figure out why you specifically want openbios on your system. Chances are that you got attracted by the name but that there are options that are providing you a better experience
- get coreboot working with seabios or EDK2 as a payload first. Then try to switch to OpenBIOS.
- get OpenBIOS working with coreboot on qemu next, then look into getting it to work on actual hardware.
- once you are confident that you understand all the components that go into your firmware stack, you can do the integration and get everything working together.
- then you will have to figure out which pieces are missing and fix the code. They're is a zero percent probability that this project will work for you without writing code.
- While i personally find tutorials for specific hardware combinations less useful, i would recommend that you document your progress and share the challenges you faced and how you solved them, when you are done.
All the best and good luck
Stefan
I took note of the concerns regarding the installation of OpenBIOS in my case.
Possibly, OpenBIOS isn't the perfectly right choice for me but the wrong one would be to stay with my current BIOS.
I turned to the coreboot mailing list and made clear I'd like to install coreboot with OpenBIOS. Finally that link was provided https://doc.coreboot.org/tutorial/part1.html. I followed the instructions until Step 5 - Configure the build > Check your configuration (optional step). As I didn't read anything on OpenBIOS in the commands I asked whether I was installing OpenBIOS at all. I've been told that I installed coreinfo, instead.
What should I do now (delete the current installation which I made, yet?) if I'd like to use OpenBIOS (with coreboot; as OpenBIOS alone doesn't seem to work) and where do I find a tutorial or guide that really applies to what I intend to do?

Yes, that is correct.
However I would strongly recommend asking the coreboot people first which would be
the most suitable BIOS for your ThinkPad, since OpenBIOS these days is mostly used
for emulators like QEMU for running older software. Once you've made a suitable
choice, the coreboot project should be able to point you towards further reading to
help get everything built and installed correctly.
ATB,
Mark.
