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.
