Write your own Boot-Sector at OmniNerd

I found an interesting article about writing your own boot sector code. Why would you want to do this? Lets say you are an aspiring Operating System developer writing your own hobby OS, or, for more malicious purposes, such as dabbling in the lost art of boot sector viruses. There is some great low level ASM code in this article to demonstrate this. This reminded me of a great Multi-Boot tool that was out a few years back called XOSL. Although grub does all the same things, it was a great little program for its time. Anyway, interesting read if you want to understand the fundamentals of the X86 boot process.
