I mean, yeah MS-DOS is barely an OS. It is nearly the bare minimum between hardware and the software on top. I mean you can just write directly to video memory

I mean, yeah MS-DOS is barely an OS. It is nearly the bare minimum between hardware and the software on top. I mean you can just write directly to video memory at a whim, just don't write to the memory as it is being read at the same time AKA CGA snow. That is its beauty and its pain.

Not only that, but MS-DOS was mostly a filesystem driver, just like the name said. All the rest came from BIOS interrupts.

  Don't forget that "BIOS" has another meaning in MS-DOS. BIOS and BDOS, remember.
