every traditional x86 BIOS loads the boot sector at the same address: 0x7C00
a free book called 539kernel starts from that tiny detail and builds an entire operating system around it
chapter by chapter you go from the first instruction to a working kernel
the whole project is https://t.co/3KskpEZXU0
