Simple Operating System

About

Assignment for course 'Arquitectura de Computadoras' (Computer Architecture).

Simple operating system written in C and ASM based from x64BareBones.

Compilation

First install qemu.

The compilation will be done inside a docker image because of old gcc compatibility issues.

Pull docker image:
docker pull agodio/itba-so:1.0

Run container sharing the volume of the source files:
docker run -v ${PWD}:/root --security-opt seccomp:unconfined -ti agodio/itba-so:1.0 //replace ${PWD} with sources root

Now inside the container run:
cd Toolchain
make all
cd ..
make all

Then exit the container:
exit

How to run and what can you do

After compilation go to sources root and:
./run.sh

You should now see a console inside a qemu window if everything worked fine. Enter 'man' as the console says to see the following options:

• invOp tests what that when an invalid operation occurs then the registries are printed into console and the corresponding error is shown
• div0 as invOp tests that a division by zero is correctly handled by the OS
• echo simple echo program that prints into stdout
• time shows hour:minutes:seconds in stdout
• clock digital clock that displays the drawing capabilities of the system and shows the use of a beep sound
• clear clears the console
• frog simple print of ascii frog into stdout
• theme used in conjunction with one of the following parameters: 'text', 'consoletext', 'error' and 'background'. Changes the color in which the system prints the different components of the console. ie, theme text will change the color in which stdout is printed.
