My attempt at making a bootloader and kernel. My attempt at making a bootloader and kernel.
## How to use
To compile, you need:
- `i686-elf-gcc` for cross-compiling the kernel
- A system `gcc` for compiling the host-helpers
- `nasm` for compiling the bootloader
- `qemu-system-i386` for emulating (`qemu-system-x86_64` will probably work too, but that is not directly supported)
If you run `make bin`, it will generate `target/boot.bin`, this is a binary file layed out as described in [the docs](docs/bootloader.md). To burn it on a USB drive, simply `dd if=target/boot.bin of=/dev/sdb` and the drive is bootable and contains an SFS filesystem with the files in `filesystem/`.

The bootloader is self-written, based on articles on [the OSDev wiki](https://wiki.osdev.org/). It's a single stage, ELF-loading bootloader in the most basic way possible.
