I have a question about 13 kernel bare bones
is this really a kernel or just a 2nd stage bootloader? It's in binary format.
The MS-DOS kernel was in binary format
Depending on how far you want your operating system to go, it can be either. If you want your OS to be a simple pet project to learn about how the x86 CPU works, it will be an operating system. If you want a full UNIX up and running, it is probably best to make it a second stage bootloader that recognizes a file system.
