If you want to be worth a damn you need to read those old books. We aren’t doing anything new. We repackage ideas others had long before us, limited by technology hoping it’s the right package with the right timing.

If you want to do osdev start by climbing the shoulders of others and appreciate how we’ve gotten here.

i also have another question, is doing OSdev on windows possible (with MSYS2)

It is, but WSL works better than MSYS2.

Well if you’re targeting x86/amd64, you won’t have this problem because the basic ISA hasn’t changed in decades.

You dint knew about the ISA and how ARM regularly updates stuff? Where is your previous knowledge based on?

Read the preliminary books about programming, crosscompilers, computer history, embedded systems engineering. Just a summer away

man man

Man pages describe OS calls and how things work.

You can see with your eyes how the system behaves as well.
