In the beginning..

In the beginning there was a tutorial...

'A' tutorial!

No!

Quite a lot of them!

But somehow I started with Robbert Haarman, AKA inglorion.

And there was boot sector. :)

Well! well! well! as you know bootsector is the first 512 bytes of the floppy media you boot from.

You can write 512 bytes of x86 assembly language code with 0x55h 0xAAh as the final two magic bytes.

There you have your boot sector. Now carefully place those bytes to a floppy disk and boot your machine.

There you go with writing your first bootsector.

That simple!
