About Powerint DOS

Powerint DOS is an operating system used for learning purposes only.
At first, the operating system was in 16-bit real mode, but now it is in 32-bit protected mode (386 version).
Due to COVID-19, Zhou Zhihao stayed at home and started the project in December 2020.
The project was about operating systems and Zhou Zhihao named it 'Powerint,' meaning powerful interrupts that we can use. After coding for about a year, the operating system had the normal functionality like MS-DOS but it was still in 16-bit real mode.
In December 2021, the writer of Simple OS, Qiu Chenjun, collaborated with Zhou Zhihao. They helped Powerint DOS transition into a new world, 32-bit protected mode, and renamed it Powerint DOS 386.
After over a year of coding, Powerint DOS 386 is continuously improving.

Build

Note: you may need to install nasm, gcc, g++ and qemu before build

First, you have to clone the repo, like this:

git clone https://github.com/ZhouZhihaos/Powerint-DOS-386.git

Second, go to the apps folder:

cd apps

Then, use make to compile the apps:

make

If you don't see an error message, then go to the Loader folder then type make in the cmd prompt:

cd ..
cd Loader
make

If you don't see an error message, then you can run flowing commands to go to the kernel folder and build the kernel:

cd ..
cd kernel
make

Or you can add run in order to start debug after the compilation:

make run

You will see Powerint DOS splitted into four images in kernel/img folder.

Done! You can try Powerint DOS by using qemu or any other virtualization software you like right now!

The following command is an example of qemu:

qemu-system-i386 -fda img/Powerint_DOS_386.img

If you need network support, add some parameters to the command and it will be like this:

qemu-system-i386 -fda img/Powerint_DOS_386.img -net nic,model=pcnet -net user
