## Disclaimer
-----------------------
For now, assumes that A20 is already enabled on your device by BIOS.
## Why Bash?
-----------------------
I like it more, and feels more customizable than makefile.
This project is not going to be permanent anyways, just some bootloader.
## Disk Mapping
-----------------------
0x0 - 0x200 -> Master Boot Record (MBR)
0x200 - 0x9ff -> Stage 1
* - * -> Stage 2
## Memory Mapping
-----------------------
0x7c00 - 0x7e00 -> BIOS MBR
0x7e00 - 0x9200 -> stage 1
## Stages
-----------------------
- early stage 1 (MBR)
The only duty of this stage is to load the stage 1 bootloader.
- stage 1
1. Detects available video memory, and RAM memory.
2. Switches to 32-bit execution and protected mode.
- stage 2
1. Switches to 64-bit execution (long mode).
2. Implements a FAT driver to load a kernel (or OS) file from disk.
