Nigel 5781f730d9 Implemented the basis for syscalls 
A software interrupt with vector 0x50 will cause a syscall to start executing.
The EAX register will hold the syscall_num.
Other registers and the stack can be used to hold further arguments.

Writing an Operating system

As a learning experience!

Inspired by people like Linus Torvalds and Andreas Kling

Interrupt handeling
W.I.P - Working on interrupt handling

Multiboot integration
Multiboot information can be read by the kernel.

Page faulting

Reading Files from FAT-16
Reading a FILE from a FAT-16 Formatted drive

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.
