My attempt of writing an OS from scratch (basically starting with the OS book by Nick Blundell)

Current code :

• print on screen in BIOS mode
• read from floppy disk, initialize Global descriptor table, load the kernel and switch to protected mode
• install Interrupt descriptor table, Interrupt Service Routines, Interrupt Requests
• Handle screen - print on screen, scroll
• Handle keyboard inputs
• Handle timer interrupt

ToBeDone :

• Memory management - malloc/free
• paging
• scheduler
• multi-programming

COMPILE: make

RUN: make run

CLEAN make clean
