What will I learn?
This OS Development Course takes you through creating a simple x86 kernel from the ground up, including setting up protected mode, GDT, paging, and stack setup, then mixing assembly with C, linker scripts, and bootloaders like GRUB or a custom one. You will also set up basic console input/output, serial logging, testing with QEMU, and practical debugging methods for a straightforward, practical learning journey.
Elevify advantages
Develop skills
- Write a bootloader: create custom 512-byte sectors and smooth GRUB handover.
- Build a minimal kernel: set up GDT, stack, paging, and secure memory layout quickly.
- Implement kernel I/O: develop printk, VGA text output, and serial debug logging.
- Integrate Assembly with C: plan kernel entry, linker scripts, and stack switching.
- Test kernels in emulators: use QEMU, GDB, and automated tests for quick feedback.
