#Not My Default Bootloader This bootloader displays a minimal publication

The bootloader only has a size of 512 bytes. Therefore I added a second stage to load a program into the memory Actually the publication loads different programs into the memory (every part is a seperate program) and from everywhere you can go back into the bootloader program.

#Make

make
make run

#Dependencies *nasm *qemu to simulate (but you can also boot directly from USB then there's no need to emulate)
