This is a minimalist kernel which prints "my first kernel" on the screen and then hangs.
- The kernel is multi-boot compliant and loads with GRUB.

Kernel 101 – Let’s write a Kernel
Build commands
nasm -f elf32 kernel.asm -o kasm.o
gcc -m32 -c kernel.c -o kc.o
ld -m elf_i386 -T link.ld -o kernel kasm.o kc.o
Test on emulator
qemu-system-i386 -kernel kernel
Get to boot
GRUB requires your kernel executable to be of the pattern kernel-<version>.
So, rename the kernel:
mv kernel kernel-701
Copy it to your boot partition (assuming you are superuser):
cp kernel-701 /boot/kernel-701
Configure your grub/grub2 similar to what is given in _grub_grub2_config folder.
Reboot.
Voila!
