# PrimusOS
A simple bare-bones 32-bit Ring 0 operating system written in Assembly x86 and C for educational purposes.
Inspired by Terry A. Davis (in memoriam).
## Dependencies for building
`xorriso`
`mtools`
## Bootloader "hello world" example
### Compile bootloader
`nasm -o bootloader.bin bootloader.asm`
### Testing with QEmu
`qemu-system-x86_64 bootloader.bin`
## Compiling the kernel example
`gcc -c kernel.c -o kernel -ffreestanding -m32`
## Generating the ISO image
`make check_dir`
`make clean`
`make primus-os.iso`
