What will I learn?

This OS Development Course guides you through building a minimal x86 kernel from scratch, covering protected mode setup, GDT, paging, and stack configuration, then integrating assembly with C, linker scripts, and bootloaders like GRUB or a custom sector. You also implement early console I/O, serial logging, testing with QEMU, and practical debugging workflows for a compact, hands-on learning experience.
