Thanks Peter,

It doesn't sound half as bad I feared it would, honestly. The way I see it, this is what I can and should do:

- Acquire the Ultra 40 M2 machine (just bite the bullet, as there's no other way around…), to be able to run the tests in a first place;

- Buy a couple of blank BIOS chips for that particular board, to use them for flashing various versions of coreboot BIOS images; if anything goes terribly wrong (workstation misbehaves, with any given coreboot image flashed), I can still use the computer with proprietary BIOS.

- Try with the last stable release, where my board is listed as supported (4.8?), then stick to it if all works well;  

- Post the test results for functionalities (hmm, where … through mailing list ?), that were marked as »Untested«/ »Not working«/ »WIP«,  as listed in the last update of the table, with a status summary of the board functionalities, or … ?

As you can see, I'm fumbling around and stumbling quite a bit,  being overwhelmed by the maze of available information on one hand, and the lack of encouraging up-to-date hints and proofs for the future on the other hand. I suppose this is where the proverbial line »welcome to the moment« comes into play.

Kind regards,

Bostjan
