I’ve been building NekoOS, a simple operating system from scratch in C & assembly.

So far it supports:= - VGA text output (with scrolling) - Keyboard input + basic command parsing

Next, I want to add a PIT (programmable interval timer) interrupt so the OS can do periodic tasks (like printing every few ticks, and later multitasking). Any suggestions on how?
