JuiceOS-Kernel32

JuiceOS Kernel32 - my x86 hobby OS kernel.

Build Requirements

This project is supposed to be built on Linux only. You may use WSL as well.

sudo apt install build-essential cmake ninja-build nasm

sudo apt install grub2 xorriso

Running in an emulator

Requirements

Windows users should install Qemu for Windows, and add Qemu to Windows environment variables.

Linux users should install this:

sudo apt install qemu-system-x86

Some presets for running Qemu are defined in runscript-gen.json, and you can use runscript-gen.py to generate them for both Linux and WSL. For this you'll need Python 3. Install it on Windows (not in WSL) if you're using WSL.

If you're using Linux without WSL, just install Python 3:

sudo apt install python3

Testing

Generate run scripts

For normal Linux (not WSL) either run this:

make gen-runs

or directly run the script:

python3 runscript-gen.py

When using WSL, run the runscript-gen.py script in the Windows environment.

Then follow the instructions, and the run scripts will be generated. Re-run the script if you make changes to the JSON config.

Run the emulator

Use any of the generated run scripts. When using WSL you can just double-click a .bat script in the explorer. On Linux run a .sh script. They all are already marked executable.

If you don't know which run script to better use, run the default/normal variant.

Running on a real hardware

For Linux users:

sudo dd -if bin/JuiceOS.iso -of /dev/sdb

where /dev/sdb - is your USB drive.

For Windows users:

You need to have Rufus. So after installing Rufus, open it, and drag and drop bin/JuiceOS.iso file to the Rufus window. After this your window must be like this:

Then click START button. In this popup select the second item:

And then confirm flashing:

That's all. But remember, THIS OS WILL WORK ONLY ON PC WITH LEGACY BIOS or UEFI-CSM!
