Building a Kernel / Operating system from scratch.

- Added boot device info parsing to the kernel - Added a pointer in the kernel to our pre-kernel BootInfo structure - Created a layout for the FAT driver - Created a layout for the virtual filesystem - Separated IDE driver from the basic atapio driver. This will ensure we are not using one or the other - The create_harddrive shell script will now actually build a harddrive image of the kernel - The virtual filesystem initializes and creates a filesystem structure for every FAT16 partition in the master boot record |

Writing an Operating system
As a learning experience!
Inspired by people like Linus Torvalds and Andreas Kling

The first scrolling boot screen. 😲
W.I.P - Working on interrupt handling
Multiboot information can be read by the kernel.
Enabled paging and am getting page faults!
Enumerating the PCI bus
Correctly identified our ATAPI device 🎉
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.
