A simple Multiboot-compliant hello world kernel with ring 0/ring 3 multitasking and loadable ELF-modules.

Requirements

Requires a 32-bit cross-compiler with libgcc and some standard headers (stdarg.h, stddef.h, stdint.h) that should have come with your compiler.

How to compile

Edit the Makefile and change TOOLCHAIN_PREFIX if your gcc is not called i586-elf-gcc. Then run make to compile.

How to test

Load build/i386/incos-i386-kernel with GRUB or QEMU.

The following command loads the kernel and two instances of the hello program.

qemu-system-x86_64 -kernel build/i386/incos-i386-kernel -initrd build/i386/hello,build/i386/hello
