Nigel Barink a77621faf5 Shellscript improvement plus FAT driver implementations
- Improved the run bash script to exit when an error occurs in one of the sub tasks
- Wrote basic FAT16 functions that should give enough information to properly implement the rest of the driver
- FAT structure namings are now in accordence with the microsoft spec of March 2005

Writing an Operating system

As a learning experience!

Inspired by people like Linus Torvalds and Andreas Kling

The goal

Writing a hobby operating system to better understand the basic building blocks of any operating system.Initially I'd like for my operating system to be able to run bash.


Operating System Technical specs/details

The operating system can print strings to the screen. The terminal/screen has scrolling so the latest messages are visible on the screen.
