Create Your Own Operating System (OS) - Kernel

In this video we will create a simple "Hello World!" kernel in C, then writing functions to display strings/numbers on a screen and also creating a simple singly linked list in kernel.

Go to following sites for information about creating a kernel in C.

Requirements for writing a kernel in this video,

GNU/Linux :- I am using GNU/Kali Linux 2017 i386 distribution .
Assembler :- I am using GNU Assembler(gas) to instruct the bootloader for loading the starting point of our kernel.
GCC :- GNU Compiler Collection a cross compiler. Any version 4,5,6,7,8.
Xorriso :- A package that creates, loads, manipulates ISO 9660 filesystem images.(man xorriso)
grub-mkrescue :- Make a GRUB rescue image, this package internally calls the xorriso functionality to build an iso image.
QEMU :- Quick EMUlator to boot our kernel in virtual machine without rebooting the main system.


To create a Bootloader in 16 bit assembly language,

In video, i said more than 6.x version of gcc is required for compiling the kernel, which is not true, it can be compiled with any version of gcc,
