FAQ
What prerequisites are needed to follow these tutorials?
A solid understanding of C programming and x86 assembly language is recommended, as well as familiarity with basic computer architecture concepts.
Are these tutorials still relevant today?
The core concepts of kernel development remain valid, but some details like build tools and bootloader versions may be outdated. Readers may need to adapt the code to modern toolchains.
Is this tutorial series complete?
The series covers booting, memory management, interrupt handling, and multitasking, but stops before a fully functional OS. It is intended as a learning resource rather than a complete OS.
