KFS stands for Kernel from scratch. The goal is to build a functional kernel, without using any existing external code. It's cut in 10 submodules.

Current state:

• KFS1: Hello world kernel (multiboot print screen)
• KFS2: GDT and stack basic shell
• KFS3: Memory and pagination
• KFS4: Interrupts
• KFS5: Task switching and scheduling
• And 5 more...

To be able to build KFS, you will need a i686-elf cross toolchain. You will find information here on how to build it for your distribution.

# with ssh
git clone [email protected]:lfalkau/kfs.git

# or with http
git clone https://github.com/lfalkau/kfs.git

cd kfs
make iso
make boot

You can alternatively run make if you just want to get the kernel binary image.
