History
Andreas Kling ee4d7c18c8 Kernel: Use a multiboot header instead of a convoluted two-part bootloader. 
The old bootloader was hilariously complicated, requiring a floppy disk with
the kernel on it, and a hard drive with the file system. This patch removes
the floppy disk from the equation and replaces it with a multiboot header.
This means the kernel can now be booted with qemu-system-i386 -kernel kernel
