could I write an entire operating system in assembly and C++?
It’s very much doable; I did exactly this with an OS I worked on last year. This takes advantage of many modern C++20 features, most of which work just fine in a bare metal environment. As others have said, you’ll have to disable runtime features like exceptions and RTTI in your kernel. A lot of it is really hacky, but this was just meant to be a proof of concept project that got a little out of hand :)

Why is my AHCI PI register set to eight 1s if I only have two devices on the AHCI?
I’ve written an AHCI driver for my OS which I’ve tested works on a few VM platforms and real hardware. I’m not actively working on this project anymore due to my current job, but maybe it can be a useful reference for you.

I know some third-world nations still use DOS and the BORLAND DOS compilers because people donate old computers to their nations.
With the right OS, old computers are still usable. Please don't throw them away, e-cycle them so they get used by poor nations that cannot afford new PCs.
