Yes, I know - I pointed out the lack of UEFI on this system in the
original post.
Newer AMD GPUs do not work at all or work randomly on some systems
with legacy BIOS since RX 500 series,
That's news to me, and I'm surprised not to have seen it better
documented; generational hardware compatibility breaks are usually made
fairly prominent, in my limited experience. Aside from a video link, any
sources / references on documenting this?
Not that I doubt that it's true, I'm just trying to get more background,
including on why and how it managed to slip past my attention.
Relatively few people want to put a new video card into a
(comparatively) ancient computer. It honestly isn't a great value
proposition--regardless of how much you spent on it a decade ago, a mid
range ryzen from a few years ago will outperform it, let alone a current
generation processor. Since nobody does this, there's no value to the
manufacturer to develop the necessary BIOS interface in addition to the
UEFI interface that will actually be used by basically all of their
customers. They do the bare minimum necessary to let someone reconfigure
their machine from traditional BIOS to UEFI, and even that is probably
working more because it hasn't broken yet than because they're putting
effort into it.
Having played with this sort of thing before, it's really not worth it.
With a big enough generational jump you run into all sorts of issues
(e.g., the new hardware pushes the PCIe bus just a little harder than
anything did before, and the aging hardware starts to flake out) and
frustrating bottlenecks. If the hardware works, just leave it alone. If
you feel the need to upgrade some of it, just upgrade the whole thing
because that's where things will eventually end up anyway...but if you
do it all at once you'll end up wasting a lot less time chasing
gremlins.
