Learning how to build my own x86 OS from scratch.

OS From Scratch

Usage

Currently the directories contain boot sector programs written in x86 assembly. To run these,

1. install qemu

   sudo apt-get install qemu	#or your distro's equivalent
   
   alias qemu='qemu-system-i386'	#for ease of use
   

2. install nasm

   sudo apt-get install nasm
   

3. enter the directory of the program you want to run, compile it with nasm, and run it with qemu

   cd hello_world
   
   nasm boot_sect_hello_world.asm -f bin -o boot_sect.bin	#compile
   
   qemu boot_sect.bin						#run
