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.
What are some alternatives?
