PolarOS

A small project to educate myself on how an operating system works on a low level. The basis for this project is the LittleOS book.

Building the kernel

You can use the accompanied Makefile or compile the files with GCC/Nasm yourself. I have used QEMU as the virtual machine for my kernel, as I dont wanna necessarily run it on real hardware at this point

make
qemu-system-i386 -kernel kernel.elf

Alternatively if you want serial output to show in QEMU console you can type

make
qemu-system-i386 -kernel kernel.elf -serial stdio
