- Tinix on ubunut 14.04
This is a series of course that teach you how to step by step writing an Operation System, Here I give the usefull comand line that how to build,run and debug on ubuntu machine, also some updates of the build scripts as the original does't works now as too old.
- sudo apt-get install nasm
cd chapter1/x # x is either a or b
nasm -o boot.bin boot.asm
# generated a bootable floppy image

# then input si to step asm code-
