# Writing My Own Boot-loader With a Very Primitive Calculator

**[Hacker Noon](https://daily.dev/sources/hackernoon)** · 7 min read · 1 upvotes · 0 comments

## Summary

In this blog post, I will be “attempting” to write my very own boot-loader with a very simple and primitive calculator. The first thing we need to do is have a file that we can run, and it will set the rest up. We need a way to print a character to the screen, set the video mode, clear the screen and last but not least, create a new line. We can do all of this in less than 40 lines of code!
