kbOS is a simple, 32 bit proof-of-concept operating system. This project was done to explore assembly, C, and operating system development.
Required libraries
- nasm
- gcc
- make
- qemu
- grub
- xorriso
- wsl (windows only)
To compile on linux
make clean
make iso
To compile on Windows
wsl make clean
wsl make iso
Note: Ensure gcc, nasm, make, grub, and xorriso are installed on your wsl image.
Execute make qemu to run.
If the os does not boot or you see a CD-rom boot error 0004, run sudo apt-get install grub-pc-bin.
