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++, mtools 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!

Boot

In kernel directory:

make full_run

you can also use make run or make img_run, they differ.

Doom Game

If you want to run Doom, after the build:

1. You can binary concat kernel/img/doom1.img and kernel/img/doom2.img. After that, run in kernel directory:

qemu-system-i386 -net nic,model=pcnet -net user -serial stdio -device sb16 -device floppy -fda ./img/Powerint_DOS_386.img -drive id=disk,file=disk.img,if=none -device ahci,id=ahci -device ide-hd,drive=disk,bus=ahci.0 -hdb <YOUR-DOOM-HARD-DISK-FILE-NAME> -boot a -m 512 -enable-kvm

2. You can also use doomcpy provided by PlantOS, see doomcpy.c.
