# OS

Simple Operating System programs starting from Bootloader in assembly to Kernel in C, and other programs like OS Calculator, Low Level Graphics etc.

Kernel contains C programs for Simple HelloWorld, Keyboard I/O etc... and little bit assembly programs for low level operations.

VGA contains C kernel and assembly program for seeting up Video Graphics Array(VGA) and drawing some basic shapes by ploting pixels.

Tic-Tac-Toe a simple tic-tac-toe DOS game with boxes, Pong-Game using graphics
