Move hello world from the bootloader into a very simple kernel system.

Add a make changelog command to output a changelog from git commits.

Add the MIT license.

Create a simple Bootloader that will state "Hello World" when loaded. Should have full make functionality built in for both images and ISO.

Find all references to 0.1a and set them to 0.1.

Add a Dockerfile to launch the ISO once built.

The bootloader and kernel currently run in 16-bit mode. This should be switched to 32-bit mode, so the kernel has more address space (while maintaining maximum compatibility with modern systems).

Right now the command make floppy is used, but it should be make image

Add badges for:

• Version
• License

Badges for climate health, coverage, documentation, etc, should be created in the requests that implement that functionality.

Add a value to the system data table in the Lilly bootloader (during Real Time mode) for the kernel to lookup video modes available on the system.

Dependent on #3.

Add -V LillyOS-$(VERSION) to the mkisofs option to give the volume the LillyOS name and version number.

Create an encryption mechanism (off by default) in the bootloader for the rest of the kernel, files, etc. This should ask for a code upon booting, which will be stored in the system table for the kernel as a seed for encryptions.

The kernel itself should be encoded in a mechanism (TBD) with this seed, with a secondary loader managing the loading of the main kernel into memory via the decryption mechanism. The wrong code will result in naturally-mangled code that is unexecutable.

Add QEMU instructions to the README for users to test.

Place the CPU in protected mode in the bootloader before doing a handoff to the kernel.

The Bootloader needs to be setup to act as a FAT12 floppy disk for highest support. The BPB and EBPB need to be added to support this.

Add a value to the system data table in the Lilly bootloader (during Real Time mode) for the kernel to lookup how much total RAM is available on the system.

Dependent on #3.

Add a make emulation command to the root Makefile to build the image and run it through QEMU for testing.

Create a table of system information for all data only available in Real Time mode to be stored in the bootloader.
