mkernel

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

make kernel

Test on emulator

make run

To test with GRUB

To generate a grub image

make grub.img

To test in QEMU

make run-grub

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!
